Perfect stick to stick with it!

I advise to everyone start with this on Zigbee path. It is nice looking with okay antenne. Firmware upload was easily manageable. Fast shipment and great product.

Great product

Have been using this stick for quite some time and worked reliably. I will purchase again from this seller.

Awesome!

Everything is fine, thanks. Works very stable and I use that with zigbee2mqtt and homeassistant. Thanks.

Works great easy to set for z2mqtt and HA

It works very well with 37+ devices, firmware flashing was very easy, documentation is very good and simple, though I only needed the basic use case for z2mqtt with HA.
Communication was also very good, and very responsive. I had a problem with tracking the item and not receiving it, and got it resent to me without any problems.

Total control over ZigBee devices

With Electrolama CC2652R I can control all my ZigBee devices and mix them together as I want. IKEA switches that command Sonoff WiFi relay - easy! Just add Node-red or Home assistant and make whatever scenario you want

The tool you want to have for your Smart Home

Like many of you, you have a reason to come here. I started out with a CC2531. It worked and because of it has been modified with an external antenna, I had no connection problems. However, after my network grow bigger when adding more devices, I became suspicious. Even having great lqi, messages got lost, switches did not react etc. I added more routers, but this was not the problem. Digging down into the configuration of zigbee2mqtt you will find a setting "adapter_concurrent" which reads "configure adapter concurrency (e.g. 2 for CC2531 or 16 for CC26X2R1)". OK, this is where I understood I had a problem. With only two messages which can be processed in parallel, after scaling well beyond 50 devices in my network it had collisions more often than I was thinking. Checking even more, you get an other detail: The CC2531 can handle 20 Zigbee version 3.0 devices. OK, since all my stuff was quite new, I well exceeded this limit. The CC2652R is able to handle 100, which should be enough for some time. Immediately ordering this stick, switching it out and all my problems were resolved. No lost messages, lqi improved (not much, but more stable at high levels). If you started to become frustrated with your CC2531, you are at the right place.

Significant upgrade

Works perfectly

Legit review from an Aussie

Arriving in Japan in 10 days

Great little stick

Excellent product

Bought this despite never having used Python previously. I followed the instructions very carefully – checking and double checking as I proceeded. At the end, after about 15 minutes, I achieved a working Zigbee communicator on my Home Assistant, which I am still setting up. It communicates with all my rad vales, even the one I put in the refrigerator as a test!

Excellent, replaced Ikea Tradfri hub in 20 minutes.

Set-and-forget Zigbee stick

The ZZh is a robust solution for your Zigbee network. Literally the bedrock of my HomeAssistant smarthome system, enabling the Hue lights, Osram smart plugs, Aqara sensors and a couple of dimmers. I run it with Zigbee2MQTT which has proven to be flawless in its execution and keeps getting better with every update. Omar is a stand-up guy that I highly recommend buying from.

Great little stick

Arrived much quicker than I thought, setting it up was straightforward but it does require some technical knowledge to get it up and running. After setup, its been working with Home Assistant with no issues! Would totally recommend!

CC2652R Multiprotocol RF Stick Works Great

Working great with my Pi 4 and Domoticz. I also installed Home Bridge and now my phone and ipod mini controls the Zigbee motion detectors and other Zigbee devices. Flashing the firmware was easy but downloading the TI software that does the flashing was a pain.

So much better than the Chinese clones!

I started out with Zigbee2MQTT together with a bunch of those cheap Chinese CC2531 sticks. After a couple of weeks, the cheap CC2531 all of a sudden stop working and I had to reflash them or simple use another one to get my smart home stuff working again. Either their firmware got corrupted (I shut the whole system down every night because I don't want the wireless stuff polluting my sleeping space) after shutdown, or the device simple would stop responding over USB. After going through this loop a couple of times, I got fed up with it and ordered the zzh! CC2652R Multiprotocol RF Stick. Took the cheapest shipping method (Royal Mail) and it only took a week to Austria.
After 2 months of operation, the CC2652R is still running, WITHOUT any of the problems I had with the cheap CC2531 sticks so I'd say it's more than worth the price! The range is also wayyyy better than any of the cheap sticks with the external antenna.

Perfect :-)

I got as a zigbee coordinator on a Raspberry pi 3 (using zigbee2mqtt). It works way better than the CC2531 I was using before that (signal was not powerful enough). Shipping was fast a well protected as well.

Great product, friendly staff

The product arrived on time, the package could have been bulkier (maybe more padding) but nevertheless, all was in place, no problems with the product. I followed the instructions, installed the drivers, flashed the firmware (great documentation from Electrolama) and everything is up and running in less than 10 minutes. I will need few additional weeks to test the range and stability of the product.

Works as it should

Stick works as it should, shipment was actually quicker than expected! And my wife loves the sticker ;)

Great range compared to a previous generic version from eBay

Didn't realise I had to flash it myself which I was hoping to avoid, but in the end figured it out and all working now. Much better range than my previous stick.

Great Product

Being new to the world of Zigbee - I chose this product when wanting to implement zigbee2mqtt - the whole ecosystem is simply awesome and Electrolama are a great provider with a great product. Amazing what you get for the money

Home assistant power house

Excellent coordinator

Really stable coordinator with a good range. Very easy to configure and such an improvement over the CC2531.

A very solid upgrade to my Zigbee network

I used this stick to replace my simple Zigbee dongle that was reaching its limits for my network and it absolutely works like a charm. Documentation on how to set this up with zigbee2mqtt is excellent and it took me at most 1 hour to migrate everything over to the zzh stick. Since then I have added at least 5 more Zigbee devices to my network and the zzh stick has been working without any issues.

Fantastic Zigbee Co-ordinator

Works perfectly

Connected this to Home Assistant and it has worked flawlessly. I have Hue bulbs, Hue dimmers, Aqara sensors, IKEA sensors, and an IKEA repeater on the network and it works great.

Perfect Replacement for CC2531

I have a lot of problems with CC2531 requiring me to re-pair a lot of my devices regularly. After using zzh for 2 weeks, there is no problem and so far so good. Although I expected the signal to be far better than it is right now (about 20% better LQi than CC2531). I contacted the seller by email and their communication is very good.

Great product, seller and documentation

This isn't a product review!

excellent - a problem solver for IOBroker

Already back in December, I have set up a Pi4 with a 2531-based USB stick and IOBroker - a catastrophy: with that, the zigbee adapter resets in random intervals (between 5min and 2hrs) with crazy log-file entries like "...unhandled promise rejection",...
With the CC2652R and it's configuration via the TI tool as described on Electrolama's website (and after assigning a new PAN-ID in IOBroker), everything works now perfect and reliable from the first second on !
I am more than happy - not a single reset or other issue since I configured the 2652-stick. Great.
A clear recommendation.

Perfect for my home automation

Very good product!

Works great

Working right out of the box with Home Assistant (ZHA) on a Raspberry Pi 3b+. Clear improvement in link quality with a number of devices in the network. Shipping was well within the estimated delivery time. Thanks to maker of the board, glad to make use of your knowledge and skill!

Very happy thanks.

Arrived in reasonable time considering world events.
Works perfectly and seems totally reliable so far. The only glitch I had was that I had to flash it twice to use via zigbee2mqtt. The first time it reported success but clearly hadn't flashed correctly - after flashing again everything worked fine.
It's good to have all my zigbee stuff running totally locally with no cloud dependencies.

It doesn't work on QNAP NAS

Shiping was Ok and it works after flashing because I tested it on my Windows laptop.
However I'd like to use it on my QNAP NAS and Home Assistant over docker and I can't make it work that way.
What I think is than my NAS doesn't have ch340.ko module instaled and that is why it doesn't appear on /dev/tty* when I plug it. And so I can't use it.
I don't recommend it if you want to use it on a QNAP NAS.

Great product and documentation

Nothing to complain about, just praise. Everything was crystal clear. Documentation flawless. Very impressed! Great product, very happy with the function. I deeply recommend the whole package.

Great product, easy setup and fast shipping!

The product arrived in under two weeks, works great, and even got a little electrolama sticker :)
The setup process is really easy, no additional hardware is required, just put the stick in flashing mode and follow the steps on the documentation.
Also, feels great knowing my purchase contributed to the great zigbee2mqtt project.

all great

Fast shipping, great documentation for an easy setup (no issues at flashing the device as a newcomer) and great performance!

Delivered next day and does the job!

Got this to replace my old CC2531 which was giving me headaches and it just... works! The instructions on how to flash the proper firmware were clear and easy to follow, the casing is just fine, and it all works just fine. Delivery was next day so... can't get any faster!

Satisfied buyer

The device works flawlessly in zigbee2mqtt. No drops in connections whatsoever and I am very satisfied with my purchase.

Works reliably with Zigbee2Mqtt, nice case.

Works reliably with Zigbee2Mqtt, and a nice tight-fit case for it. With a previos CC2531 based adapter I had pinging issues in a Zigbee network of about 10-15 devices, now those are gone and communication works reliably. My device's USB A connector had a little dent after the shipping as it seemds to have gotten squeezed in transport - no big deal, but some sturdier packaging my help. Thanks for making this great device!

Great product, great delivery

perfect quallity

Shipping took 1 week. so pretty fast.
going to use it with zigbee2mqtt. perfect quallity pcb.
going to replace the CC2531 i have right now.

Perfectly functional as a ZigBee coordinator

Best Ever

Very fast shipping, easy setup, just a great product and seller. Very happy that I bought this stick.

Great stick for Zigbee2MQTT

I was up and running with Zigbee2MQTT within half an hour controlling my vendor I and X lights and sensors. Documentation on flashing the firmware was clear, range is good and I haven't encountered problems with any devices. There were no shipping issues to EU despite potential Brexit hurdles.

Fantastic replacement for the CC2531!

Perfect

I can only support all the other positive reviews. Quick shipping, clear unambiguous instructions for flashing and an immense upgrade from my CC2531, as the linkquality and reach is extremely good now. I can only recommend warmly..

Works.

I have a simple zigbee network and it has worked fine so far. It reaches all devices in my household, also in places where the wifi from the router is not visible any more.

Neat. Simple. Clear. Works.

New to this corner of tech I ordered this based on the reviews and recommentation of the Zigbee2mqtt site.
Delivery was fast, flashing was easy and setting it up with Home Assisatant was a breeze.
Flashed on macos then running on a Synology NAS with HA in a docker container... Loads of potential barriers to a smoothe ride.
All fine and paired with my first device within an hour (and I was taking it slow).

Everything was ok.

Delivery in Russia was really fast, after reading the documentation i successfully flashed the stick. It works as expected.

Great Zigbee controller!

There is a clear reason why this Zigbee controller is so recommended. It is easy to use and works well. The instructions on the support website are clear and easy to follow. Keep in mind that just as the description and packaging indicates you have to flash firmware onto it before use. The instructions I followed required Windows.

Very recommended

Works like a charm

My objective was to get rid of my xiaomi hub. And that worked like a charm. The stick arrived within two weeks from ordering from UK to NL. And using the electrolama quick start was easy enough to configure for HA use. Was up and running within 15 minutes end-to-end.

Perfect for the Zigbee network

I cant compare it with any other RF stick as this is my first one, but it does the job perfectly and til now I haven't had any issues.

Works as expected

It works just as expected - the setup is a bit tedious, but its well documented and works fine.
If you use a RPI4 or similar, I would highly suggest you buy a usb-extension cable as well. Without it, I had a range of only a few meters - with it, it works even a few rooms over.
Shipping to austria took 2 weeks from order to delivery.

Perfect

Amazing!

Replaced my Philips Hue Hub and Samsung Smarthings Hub with this and couldn't be happier. A lot more functionality and reliability at fraction of the cost.

Great replacement of proprietary bridges

Installation was easy, stability is great.
I made a shipping address mistake, which was quickly fixed.

Great quality, clear instructions, fast shipping.

ZZH! Is great in every way:
-well designed and quality product
-instructions for flashing are clear, and it is easy
- working well as coordinator or repeater (I use it in both functions)
- stable device, can handle directly more then 70 end-devices
- the range is enormous, can cover a 2-floors house with concrete floors and 40cm thick walls

Perfect

I've been using the zzh! for over 2 months now and it has been flawless, just works and hasn't let me down yet.

Excellent device

Excellent device, 10x more powerful than basic cc devices, 1 was enough to cover my needs when 3 cc2531 were needed before.
Fast shipping and delivery despite covid issues.

Great product and an easy (for pandemic times) transaction!

The perfect addition to my OpenHAB setup

Fantastic stick

Prompt delivery, nicely packaged. The plastic moulding fits perfectly, it comes with an antenna. And best of all the stick works so much better than my previous CC2531. I've got about 40 devices hooked up all working perfectly. I've bought a few of these, one as coordinator and others as routers. Flashing was _fairly_ straight forward (instructions and scripts could be improved but wasn't a huge problem)

Great and Highly Recommended

Worked straight out of the box with zigbee2mqtt, has been incredibly reliable and the purchase process was smooth. Thanks!

Really reliable device

Ended up buying 2 of these in the end to replace a CC2531. Since upgrading I've had no device dropping off like they were before. I've got it setup with Zstack3 on Home Assistant using ZHA and the other one as a repeater and works really well. The device is really well made and the case fits it like a glove. Highly recommended.

Exelent quality

The device works perfectly, fast delivery, the quality of the solder is exelent and although it does not improves the range over the older cc2531, the system is allot more stable. Iwould recomended 100%

Great little stick

Works great, been using it for a month or so with Homeassistant & Zigbee2MQTT.
My previous CC2531 worked okish for a few weeks then died - this works far better.

Great!

The stick works perfectly, it is on an RB4 running on zigbee2mqtt. It recognizes more devices than Elelabs running on ZHA (my old one, even slightly faster, but support is nonexistent). Very good, I recommend.

Good Range easy installation

Using it since weeks flawlessly on iobroker with the zigbee plug-in to control tradfri and hue devices

Great upgrade

I upgraded from a CC2531. The signal quality is vastly improved. I had some stability issues with the CC2531 and the zzh! CC2652R has been rock solid so far. Works very well with Zigbee2Mqtt and Home Assistant. Was very easy to flash using Windows Server 2019 VM on ESXi. Don't hesitate to buy.

Perfectly works with Home Assistant

New home assistant user!

New user of HA.. oh boy oh boy what did i open here! Been reading way too much about automation for a few weeks and i created many needs for myself ! One of them was been able to use Zigbee stuff. I just received the zzh! stick to canada and the shipping was very fast! (1 week to montreal). Flashing it with the instructions provided went smooth, HA now see the dongle. I just need to buy some sensors now ! Thanks.

Really nice and perfect for my use case

I'm using the zzh with zigbee2mqtt and homebridge to control devices thru HomeKit, the communication is fast and very reliable, it was very easy to use the documentation to flash the stick. I recommend to everyone that want's to use this with a RPi and Homebridge. The shipping from the seller side was very fast, it might get stuck in customs depending on your country, it took me a little bit more than a month to arrive.

Hassle free

Purchased it as my ticket into ZigBee world. Everything works as expected. Trouble free and reliable.
As I don't have any prior experience I can not compare to other similar products but I'd still say it delivers exceptional value.

Great work

Keep up the great work and fast delivery, in my case to Germany.
The device works like a charm.
Thank you!

Worth the upgrade from CC2531

Really worth the upgrade from CC2531. The signal is better and the devices are responding faster.
I'm using it with zigbee2mqtt with more than 25 devices.

Amazing. I love it.

So much better than my old CC2531. With this I could switch again from deconz to zigbee2mqtt. ( ... ).

Terrible Shipping

Works perfectly

Followed the linked flashing instructions and it's worked flawlessly since. The cc2531 it replaced constantly had issues, so this is a great upgrade.

It works!

So there are cheaper stick out there. But the documentation won me over. And u get ik great tiny sticker, wat more do u want.

Excellent product!...

International shipping like a charm!... easy to flash, highly recommended!
Using it with zigbee2mqtt with many devices, perfect!

Does the job for me!

I was running Home Assistant on a Raspberry Pi 4 with a Conbee II stick. It was ok but as I increased devices to 30+ it started to get a bit temperamental so I decided to upgrade to one of these mini PC boxes. Got that, installed Debian, Docker and HA Supervised, installed Zigbee2MQTT, plugged the CC2652R in and away it went. Works perfectly in my average sized 3 bed house with 62 devices. I'd definitely recommend this.

Excellent product

I replaced my old stick CC2531 with this new which can communicate with more devices. Now my ZigBee network is more stable and without problems.

If you are aiming for the router, pick a different product.

I've bought zzh! to use it as a router, to extend coverage. Before buying even contacted the seller to make sure everything will work, but never got any response.
And guess what, the router functionality is not working. You can flash the firmware without any problem, but the stick will not connect to the existing network, the coordinator does not see it. The problem is already reported on GitHub, but for the last three months, nothing happened ( https://github.com/Koenkk/Z-Stack-firmware/issues/260 ).
So, if you need a stick that will work as a router, look for another product.

Simply works better than all others

Great design.
Best in class reception with the help of the external Antenna.
It is apparent that great detail went into the design of both the electrical and mechanical fixture.
Fully documented to help you get started as quickly and easy as possible.
Nice surprise, the most important part; The Lama sticker :)

Produc is ok

Product seem ok from all points of view except one. I expected LQI of devices to be higher (this can be something related to my zigbee network not sure 100%) however I have to mention that ZHA network with Elelabs was more solid with the same settings I use now for Zigbee2MQTT. Don't get me wrong network works and all is ok except some devices relatively close to coordinator have very low LQI (usually under 20 LQI and sometimes under 10 LQI) that's the only complain. In rest product works great.

great!

Shipment should be as option available (DHL or Fedex) because thru normal post service is very slow also in my country LOL

Works as intended

I purchased one for Home Assistant.
Documentation was easy to follow, and it works.
My aparment is kinda small 37 m^2, so range was not an issue for me.
Nothing else I can add. :D

What a bliss

Works perfectly with Homeassistant

Fantastic project

Works like a charm - thanks to the perfect documentation and the nice hardware.
It was really fun to setup my RaspberryPi with this stick and controlling lamps and powerplugs via mqtt.

Awesome tool!

I bought the stick for some Zigbee tinkering and I couldn't be happier. The stability is perfect, the range is more than good, and I even got a little llama sticker with it :)

Excellent kit

Quick service, good product, easily programmed, reliable

Arrived quickly. I bought it as a more capable update to the standard cc2531 running on a Pi4, I found it very easy to programme the unit for use with HomeAssistant using the TI programmer solution. Works fine, no problems.

Excellent product and service

Excellent product and service.
Quickly delivered and works as advertised and expected (purchased based on HA recommendation).

Works really well

Can not use on my config

Good stuff

Flashed as described in manuals. Device works as expected.
Documentation is very good too. Thanks!

Works great, no problems with HA+Zigbee2MQTT with zzh!

Amazing product. Works perfectly!

No problem at all migrating 30 devices from CC2531 in Home Assistant with zigbee2mqtt.
Recomended! Communication with seller was good too.

Works great out of the box

Great work on ZZH! Replaced my CC2531 and it's much better. Overall I'm really happy with the results. Shipping was also very fast. I would highly recommend

Everything is good

Great!

Very good Stick!

The shipment arrived very quickly. Product documentation is very good for me. 10 minutes and everything was ready to go :) Range and speed of operation excellent. I definitely recommend.

High quality zigbee 3.0

Great Product, Fast Shipping

Ships very fast, product is great and documentation is also good. Works like a charm with zigbee2mqtt. Very good range. Definitely recommended.

Wonderful product!

Totally wasn't disappointed. I bought it with the intention to use it with Zigbee2MQTT and specifically chose this one out of the two recommended ones because I like the "style". Who can't trust a Lama?
Documentation is well; as a first-timer I needed some round trips but I already PR'd them on the documentation, so that's totally fine.

Great device, well worth the money

Great product for integrating zigbee in your home automation

Nice build quality, very professional.

Works like a charm!

Flashing the dongle according to the instructions was super easy and it works without a hitch with Zigbee2MQTT. I'm super happy with it. The order was processed without delay and the seller even sent a pic-as-proof of the drop to Royal Mail.

Everything perfect

The product is well packed, amazing quality, paired all my devices easily replacing an old cc2531. LQI from all devices is much better now. Flashing was super easy, just pressing a button in the stick and done.

Used for a homeassisstant project

The instructions are clear, so flashing with the appropriate image was a straightforward process. The seller has taken time to curate the various instructions - the important thing is to read everything before diving in.
This was my first introduction to this site - so a good first impression.

Thanks

Produkt is ok. Thank you.Produkt is ok. Thank you.Produkt is ok. Thank you.Produkt is ok. Thank you.

Great Zigbee-stick!

Replaced my old 2531 with this one. Now 2652 lives on the first floor of our house. Flashed 2531 as a router and placed it on the second floor, now house has 100% coverage with decent link quality.

Everything works and nothing to complain

The stick is working perfectly as my ZigBee coordinator. I flashed the firmware as documented on the website and had no problems. A later update of the firmware was no problem, too. At the moment, I have 14 devices connected and haven't encountered any issues. It is a top product!

Very steady and works as expected

Great working Zigbee coordinator

Works great with Zigbee2MQTT

Replaced my Hubitat with the CC2652R stick hooked up to a Raspberry Pi running Zigbee2MQTT and integrated with Home Assistant. Been working great so far.

Works great

Fast delivery and the zzh works as intended :) I have it working on my desk now. Thank you for making this product

Great product, works well, comes with a fun sticker :D

I'm using this item with Zigbee2MQTT in conjunction with Home Assistant. I'm using a variety of largely IKEA and Sonoff Zigbee devices with these dongles - two are configured as routers and one is a coordinator. It was very quick to get them operational and they have greatly expanded the range and reliability of my home Zigbee network. Excellent purchase. Thanks!

Nice piece that zzh!!!

Although I have to recognize I experienced some problems with a raspi, in the end I managed to install it in a docker container. Runs like a charm!

Top

Work perfectly with zigbee2mqtt. I had some trouble to flash the device because I didn't read well the documentation.

Superb

Bought to provide a raspberry pi running home assistant with zigbee functionality. Simple to set up with the documentation online for someone with relatively little experience in this area and works perfectly. Great stuff!

Happy overall

Took more time to receive it then expected, but i guess its understandable in the current situation. I brought the stick for replacement of the CC2531 which are used for quite some time, initially i do not have any complains with CC2531, but after adding more devices to the network i start to have issues - disconnecting from network and need to repair in order to fix, slow response quite often .. . Now (about a week of use ) with CC2652R all seems to work quite good, no complains at all, hopefully will stay that way :). Overall i happy with the buy, recommended for larger network of devices. Thanks!

Have not received the product

I was asked to review the product but it has not arrived yet. I guess I would be able to give a more informed review when it arrives.

Perfect

Not tried yet, waiting for raspberry... The packaging may be better, almost was opened... PCB top quality.

zzh! CC2652R Multiprotocol RF Stick

Works great, as expected.

Zigbee network seems to respond faster with this new stick. Also supports a lot more devices that my initial cheap stick. Happy with communications from the seller and glad that people are taking the time to make and ship these products so I don't have to get up and use my analog light switches like I did way back in 2018

Replacement of cc2531

I replaced my CC2531 zigbee coordinator with the CC2652R Multiprotocol stick from Tindie. I achieved a great improvement in performance and transmission distance. The delivery of the stick went reasonably well (despite Corona). Great product.

Using with Zigbee2mqtt

Using with Zigbee2mqtt, works like a dream! Good range and relatively straightforward to set up. working well with HA/Zigbee2mqtt set up

Perfect product, perfect experience

Bought it as a replacement of a ConBee 2. The zzh! is a lot better than the nightmare with the bloated deCONZ bullsh*t.
The documentation is pretty straightforward and the "customer experience" (shipping, handling, everything) was absolutely perfect.

Good value! Works great!

I have been using zzh! from around august 2020. I could not be more pleased with this device. Super stable and good rf coverage.
I was one of the unlucky buyers in june 2020 who received a unit from a broken batch, but when it was replaced with a new device a while later all was as good as expected.
Excellent communcation from seller and nice documentation on flashing etc.
I plan on buing one more zzh! for my parents as soon as the store opens up again.

Great product

Works great as a coordinator for Zigbee2MQTT, big improvement over the old CC2531 with 40-50 devices on the network. Stick look&feel is very good and professional. Shipping was fast.

Fast shipping, good support

I got a prompt support with answers when I flashed it with wrong firmware and locked the bootloader. Luckily I had the programmer so I was able to unlock it. The stick is now working great for a few months with RPi3 and HA via zigbee2mqtt. No problems at all. Good range. Will probably buy another one for additional experimenting.

Does what is says on the tin!

Currently using it with Home Assistants ZHA implementation and it is working surprisingly well.
Less latency than going zigbee2mqtt/hue hub <-> ha route. :)

Useless

Great little USB stick

Great little device, great communications and quick postage.
Not having used any of the zigbee USB sticks before I managed to get this up and running with Home Assistant and Zigbee2mqtt within a couple of hours (would probably have been quicker if I wasn't working on multiple things at the same time).
Would definitely recommend and buy again.

Great communication, great product!

Great communication about the PostNL screw ups in my local country. Package finally arrived, and product works amazing! Thank you!

Great

Even the product as the seller are great! Thank you (again) so much for all your help! The seller is really kind and searching for the best way to make their client happy! The product works really great!

A great little ZigBee stick - The Llama is excellent!

Got this to upgrade from a CC5321 which was struggling with my 20-odd devices.
Really well documented, both for custom apps, and for my common use case with Zigbee2mqtt and Home Assistant; setup took just a few minutes and it's running very smoothly.

Excellent dongle!

I've been using a CC2531 for a while now, ever since moving away from SmartThings, and the dongle was a huge headache, with devices dropping from the grid, and repeated need to disconnect and reconnect in order to permit join.
Ever since I moved to the CC2652R, all my troubles are gone. All 18 devices are constantly connected, including some that misbehaved on SmartThings. Response is also immediate.
A really excellent buy!

Easy to use, great product

perfect.

Cc2531 higher compatible product.
It works very well while using in zigbee2mqtt.
You have applied and sent the inquiries and requests accurately.
Thank you.

Works like a charm.

I bought it about 4 months ago. I'm using it with zigbee2mqtt. Flashing was easy, and it has been working very well ever since.

So far so good! Zigbee on Home Assistant in Docker

Perfect HomeAssistant ZHA adapter

Replacement for CC2531

The zzh! purchase is to replace the CC2531 and with the excellent instructions and a little re-pairing, I have connections that never worked before. Certainly worth the change. Thanks

Great product, good docs.

Well put together and thought out, arrived very quickly over the holiday period, which h was a bonus.
Would highly recommend this to anyone using Homeassistant with zigbee

Easy to use product

I got this product and it took me only 15min to get it in use. Documentations are very good and specific.

Poor signal quality

Delivered faster than I expected

Easy to install Zigbee-stick

Easy to install Zigbee-stick for home assistant. Works fine! Shipping was quick. Product was packed well.
Documentation took a bit of reading for a noob :)

Using this as a zigbee USB stick voor zigbee2mqtt

I received the product in the expected time and it was packaged well.
I'm using the stick as an upgrade to the cc2531 stick. The zigbee communication is a lot more stable now.
It is very easy to install the right firmware, if you are used to playing around with this kind of stuff 😉

Excellent

Brought the zzh! to use as a coordinator in my giant Zigbee network. An additional motivation to choose this board is the fact that part of revenue is donated to the owner of the project zigbee2mqtt, the master of universe: Koenkk.

Excellent

A fantastic product. Nicely presented, easy to flash, and I got a free sweet!
Got the to replace my cc2530, as I had far too many items for it to cope, and it was failing constantly. I'm now up to about double the about I had, and the zzh hasn't let me down once. Highly highly recommended.

Excellent dongle for Zigbee2mqtt

I have been using this dongle for a month now in my Zigbe2mqtt bridge and had no stability issues whatsoever. All my devices were promptly recognized and I can reliably communicate with them.

This stick has been awesome

Using the ZZH with Z2M and its been great. I originally had the Conbee II stick and it was nothing but trouble, now with ZZH, no issues at all.

Great product to create zigbee network.

I use zzh as zigbee coordinator. It was easy to flash firmware and use. It has good range for my house which is one floor 13x14 meters, brick walls, concrete ceiling and floor. All devices works fine. One immax light behind several walls needs to use zigbee plug or another bulb as repeater. As I do not want to move coordinator closer to center I am happy with this mesh architecture of zigbee network and that this device supports it. I connected it to tronsmart r28 box running armbian linux, zigbee2mqtt, mosquito mqtt broker and domoticz home automation software. With domoticz I use zzh and rflink to control different zigbee and RF devices. From android phone running termux, python and paho mqtt python module connected to mqtt broker I turn of zigbee plug to stop charging when phone is charged to 85%. I am satisfied with this product.

Excellent product

Everything runs as expected and described. Flashed the firmware and the device is running on zigbee2mqtt with more and more devices without any issues (currently 25)

Excellent communication and shipping time.

The stick is also great, no issue with it. I use it with more than 30 zigbee devices with zigbee2mqtt.

All fine

Works as expected. Fast delivery. Easy setup. Proper packaging. Good communication. Everything fine.

Perfect no issue at all.

Perfect product. Works like a charm.

Migrated from cc2531. There was some challenges during migration and I have to rebuild all network from the scratch, but there is no issues since that. Everything works stable and predictable. This is just a magic to use it after cc2531.

Great device for home automation

Very nice built and shipped surprisingly quickly given the current... situation. The documentation covered everything I needed and the stick works flawlessly since the setup!

Excellent device, great price and a fantastic seller

I purchased this device to replace my cc2531 as my zigbee network was starting to get too large for it to handle. This device is excellent, flashing it with the firmware is a little tricky but the seller was fantastic in his communication to help out! The signal range for me isn't any better than the cc2531 (which had an external antenna too) however the reliability of the devices is greatly improved and the response time is slightly faster. I love this device and would highly reccomend it to anybody! I use this device plugged into my Intel NUC running Proxmox with Home Assistant VM for my automations.

Everything fast

Fast delivery
Good packing
Easy to follow documentation for fast setup
Product working as expected with Home Assistant

Excellent little stick

Great all round!

Does what it says on the box

Ordered the item after seeing it on zigbee2mqtt.io
Nifty little device, it's doing what it's supposed to do wonderfully. I am using it to control some IKEA smart things.

Works really well.

I’m using this in Zigbee2mqtt. Works like a charm, much better than my old zigbee setup that’s for sure.

Quick shipping, product works as advertised, recommended

Using it for a fairly large Zigbee network, spanning a 3 story house. Quality is much improved compared to older dongles.

My ZZH has been running for a few weeks now, all is fine.

I am using this stick for Zigbee2MQTT, running on Homeassistant. It took me a lot of work to get this running. But that is what the christmas holiday is for! Took a while to get the stick ( 10 days), but I guess it's related to the busy delivery services. In the end all is well, all my Zigbee devices have been connected for a few weeks now. No isssues.

Well documented

I was amazed by quality of documentation for this stick. It covered exactly use cases I needed, therefore I saved me lot of time experimenting.
The only hard times I had was to convince Home Assistant Zigbee2MQTT to connect this stick. But after 4 hours of experimenting with different /dev/ttyWhatever, it started to work (don't know how).

great device!

Excellent device, perfect for zigbee coordinator role. Easy to setup, good documentation, very reliable in operation.

非常实用

Finally - no glitches...

overall the experience was good

Great product!!! Using it with zigbee2mqtt and domoticz. everything went good using the supplied documentation when flashing with coordinator firmware. recommended.

really good service and good device, thanks!

Got my zzh shipped in 2 days, really good service!
Documentation is fantastic.
For Home Assistant OS user + zigbee2mqtt: the usb device in the documentation is indeed right (on rpi4) . The device from the host in mapped in the containter as /dev/ttyUSB0 by docker, even if it has another name in the host.
Thanks!
And I have a lama head instead my laptop windows logo now :-D

Easy to setup - great performances

I use it with Zigbee2MQTT and Aqara devices. It works flawlessly for more than a month now. The range is great. Every zigbee device has been responsive, no more latency with door sensors for example. I also tried ZHA with Home Assistant but I prefer using Zigbee2MQTT to keep things separated. I would recommend it for zigbee networks with 10 to 50 devices without a doubt. I can’t tell for bigger networks as I didn’t test it.

Seems to work great, fast and range is good.

Fantastic service!

I had a issue where the first package was lost by the danish postal service. When I contacted Omer, he was VERY serviceminded and helped me shipping a new device over to me. So can only recommend purchasing from here!

Better than CC2531

Stronger signal than CC2531, better link quality. Faster response to commands sent. Neat case, better than bare CC2531. Good communication from seller. Recommended👍

Could not be better

Awesome stick for large zigbee network!

I have purchased this stick to replace my CC2531, with CC2652 now i have stronger signal than before and connection for some sensors became more stable.
I am recommending this stick if you are going to build large zigbee network.

Great product and seller

Great product and seller!! Shipping to The Netherlands took very long but that was because of PostNL. The seller kept me informed about the actions he did to speed up the shipping process. I definitely will do business again with him.

nice product for a nice price.

Shipping took long, but that was to be expected with Covid.
ElectroLama did a LOT to help us, and was on top of everything.
good communication, lots of effort from his side, lots of work must have gone into the tracking alone already.

Just great!

Best purchase 2020 for me! Working perfectly, great range cover. Not faild me once. Replaced my old crappy cc2531

Issues with local post, but good effort and communication

5 stars

Awesome product and from a friendly seller who offers a lot of support and customer service for his product.
Shipping took a while but that was due to PostNL.

Excellent

Very good product. Shipping was ok, considering pandemic and brexit. Stick works ok, I am controlling about 30 zigbee devices via zigbee2mqtt and home assistant. Flashing was easy. In conclusion, I woul recommend this stick to anybody.

Great product overall!

I received my zzh without a problem! The documentation is easy to follow, and I was able to add zigbee protocol to my domoticz automation system

Perfect partner for Zigbee2MQTT

Infinitely better than the cheap $5 USB dongle and proven more reliable than the Conbee II. Well worth it.

Got it working after issues with shipping and integration

Better than my old cc2531

Better range with the antenna and more devices without reconnection. I use it with home assistant/zigbee2mqtt on a rpi4

Zigbeestick on steriods

Perfect product

Zzh! stick looks well designed and works as described in the complete and clear documentation.
It was shipped a couple of days after order, as indicated.
Unfortunately dutch postal service PostNL caused a shipping delay of almost 5 weeks, but this was completely out of Electrolama's control and Electrolama went out of his way to try getting the delivery process unstuck and provided fast replies after inquiry, as well as regular updates.

Awesome product - Delayed due to PostNL - Good communication

Works like a charm.

2 sticks delivered to Croatia in a week, safely packaged, with basic flash Led firmware. Followed documentation on site to flash needed firmware. Testbed RPi4, Z2M paired to dozen of various manufacturer devices like switches, dimmers, plugs, lughts, motion and door sensors. Range adequate not noticeable pairing/connection issues so far.

Very usefull and nice

Quick delivery

Stick works like a charm. Easy to program and connect to Zigbee2MQTT ( in host machine) + Home Assistant (Hyper-V virtual machine).

Does the job!

Хорошее качество связи и стабильность работы

Использую zzh! CC2652R на Raspbery Pi 4 с Home Assistant и Zigbee2MQTT вместо CC2538. Качество связи намного лучше. Все работает 24/7 очень стабильно. Немного неудобно перепрошивать, но я справился. Я остался полностью доволен.

Cool device for my smart home system

Works great with zigbee2mqtt.

Works great with zigbee2mqtt. I upgraded from a CC2531 to this and it works great. I had to rebind my devices.

Never received the CC2652

Not working

The dongle doesn't work, I got an error when i try to flash it.
Shipping OK
I can't use it, money wasted

Great for home assistant!

Good product, excellent communication

I ordered the zzh! stick for use with zigbee2mqtt and it works like a charm, the device feels very good quality.
Even better the communication with Electrolama. Not only did they ship the device in just a couple of days, I had to contact them because an issue with shipping and they responded kindly and promptly.

Excellent

I am using it with zigbee2MQTT and it works very well. Extensive documentation made it easy to set up. Good communication from the store, and I was updated quickly about DPD some shipping issues. It took about a week to receive it here in the Netherlands.

Super Fast Delivery

Received 3 pcs zzh! CC2652R only took 3 days to received the items and works so great on HA Blue! Recommended!

Good upgrade from CC253x USB sticks

Order was delivered in 10 days from UK to California. Nice packaging including a sticker. Good docs on the website and everything worked first time with zigbee2mqtt and Home Assistant. I am getting better coverage with the included antenna.

Great product, fast shipping!

Item was shipped fast and arrived only 7 days later in germany, despite the virus and christmas chaos.
Works well, no issues so far.
Would definitely buy again!

Simply Amazing

Great Product and Fantastic Support

Amazing Product and Customer Service

Great device and nice tinkering experience

Awesome!

Fantastic bit of kit!

It arrived super quickly and everything just worked right out of the box. Well made, nicely finished and gr8 customer after care - could not recommend highly enough for Zigbeetomqtt users! I also got an Electrolama sticker which is now on my Laptop ^_^ thank you so much!

Electrolama is amazing

Great product, compact design, perfect documentation. The item shipped very fast well packaged and with a sticker as gift :-)
Thank you very much Electrolama, you have done an amazing work!

Really great !

I bought this product to run zigbee2mqtt in home assistant because I had some signal issues with the CC2531 stick.
The zzh stick is really great. I have no range issue anymore and the signal is fast!
I don't have a lots of computer skills but there are great informations to flash and integrate the zzh in Home assistant .
Moreover, I asked technical questions before buying the stick and I had great responses of the customer's service support in less than one hour!
Usually I don't let a comment following a purchase, but I really want to for this one.
This is a reliable company, with reliable products. Thanks to them.

...

Works really well. Night and day difference compared to CC2531. Documentation is clear and on point.

The perfect Zigbee adapter for Zigbee2mqtt?

Amazing Product

Great product overall. Works flawlessly with my Home Assistant setup. Documentation steps are quite clear on how to flash the device. Would highly recommend it to anyone.

Got it (quick), flashed it and runs within home assistant

Everything OK!

The package was delivered quickly. In addition to the CC2652 Stick, the package contained a nice accesory (candy) :). Stick was delivered with a pre-programmed test program blinking LED. I bought it as replacement for CC2531. I easly flashed and ran it. Very good documentation. Works noticeably faster than CC2531. Thanks.

Above expectations

This is a really great product. I'm using it with zigbee2mqtt without any issues. It can easily handle and manage more than 83 zigbee devices.

Superb product and excellent support

Works fine.

No problem to get the stick programmed and to get it working for my Domoticz configuration.
Recommended.

Works fine as zigbee coordinator

Using it with zigbee2mqtt, bought to replace a CC2531 that seemed to be struggling. Took 2 goes at flashing it before it worked, but after that re-paired all my devices and everything works well. Nice that you don't need any other hardware to flash it, which probably makes it cheaper than a 2531 in the long run.

Quick delivery and works as described

Setup with a Raspberry Pi and working well.
Documentation was quite easy to follow to setup, would be good to offer with an option to come pre-flashed though.

Everything in order

Works as expected, flashed without any difficulties. Improved range and responsiveness of my ZB network over the CC2531 which is now used as a repeater :)

Great product for zigbee2mqtt and Home Assistant

Excellent upgrade from CC2531

Great product and great support

I just wanted to say thank for creating this great zzh! CC2652R Stick. Flashing it is easy, it works like a charm and it has a good casing.
Had also contact with Omer directly and all questions got answered fast and kind.
Keep up the good work.
Greetings from Germany.

Great device and documentation

Used with Zigbee Home Automation. I flashed the firmware in few minutes reading the documentation. Everything is working perfectly. Thanks !

Excellent product, excellent seller

The stick works like a charm in two different locations in combination with zigbee2mqtt and HomeAssistant. Also, shipping was quick and the seller is really helpful. Highly recommended.

Perfect for Home Automation so far.

I've been using this little stick to build a zigbee network for my smart home installation. I'm using HomeAssistant with the native ZHA integration and it just worked right out of the box after flashing the zzh! stick. So far I have about 10 IKEA Tradfri devices managed without a single hitchup. Good Stuff!

Recommended product and seller

I bought the item to enhance my home assistant setup.
The stick works as expected and Omar has been really helpful regarding a few limitation that is out of his hands to improve.
I have discarded my proprietary IKEA gateway and thanks to the zzh! I have not access to much more customizations.
The item was shipped quickly but was slow to arrive - but on account of the postal service. Therefore a four star rating on shipping.
Omar was really serious checking up on delivery and offered a replacement shipping. However, the package eventually showed up after nine days, which is unusual for UK->Denmark.

Perfect ZigBee stick

I have replaced obsolete CC2531 with this new CC2652R chip. Works flawlessly over long distance. A small sweetness included ;) Highly recommended.

Great but

Really excellent bit of hardware, the real pain comes with flashing it for Zigbee use. The instructions are really poor, finding the firmware to flash is harder than it should be, and did I say the instructions are really poor (in fact plain wrong) leading to many hours of frustration. Started out trying to use Windows = no way, so installed Linux on a virtualbox. A lot easier with Linux but still the instructions were wrong, took a lot of playing to finally find the secret and it flashed dead easy. Either these need selling pre-flashed or much better and correct instructions provided.

Good product, terrible shipping

Great for zigbee2mqtt automation

Very nice adapter, works with Nanopi NEO Air. Would be a nice option to order the adapter without the USB header soldered on the board and with ipex antenna connector. Also the current antenna header thread is too short if you plan to place it inside a 3d printed box and stick the antenna out through a hole - you cannot fix it to the box with additional screw... you wont be able to fully mount/screw on the antenna anymore.

Great product, easy to flash, fantastic range.

As the summary says, no problems at all, a great product. Wish the shipping to Europe was a little cheaper though.

Looking forward to it working reliably with homeassistant

Definitely a good buy. Great product, great seller.

Works great with Zigbee2mqtt and Home Assistant

This replaced the CC2531 as a Zigbee coördinator, because I wanted more range and possibly more devices. Instructions for flashing were clear and the stick works very well. Also really nice that it comes with a case.

Excellent zigbee router

Major improvement over CC2531, and the seller handled the faulty batch admirably. Highly recommended.

Works well and a brilliant service

Awesome device, quick delivery and well documented

The shipping was a breeze. Device works as shown and perfectly with zigbee2mqtt for HomeAssistant.
The documentation helped in the process of flashing and / or setting up the device for zigbee2mqtt.

Beautiful Little Device

This device plugged in, was flashed with the necessary firmware and was controlling my ZigBee lights in about 15 minutes after unboxing the thing.
Very well made, a polished little product. I've bought another one as a spare because I already love this one so much.

Good product and good seller !

Shipping has been quite fast and well packed.
Informations for flashing are available on the site and explain how to flash with different platforms (PC, MAC, linux).
Regarding the product itself, I upgraded my domoticz solution based on raspberry Pi3 and cc2531 dongle, with 40 devices. Before switching I took some snapshots of the signals strength of all my devices.
After switching all the signals are higher (I did not know the value could be over 100, even 200 for some which are at 2-3meters from the dongle) !
It takes time to re-pair all the devices (around 40 devices), but it worth it. I have even been able to pair additionnal devices which were not anymore accepted with the cc2531 (+ 6 routers).
So, thanks Omer for the good job you performed !

Great little stick for zigbee home automation

Upgraded to this from a CC2531 and all is running well so far. Case and antenna are great additions and make the product that bit nicer.

Fantastic stick for use with OpenHAB

Great upgrade from cc2531

I've used it to replace my cc2531 with zigbee2mqtt. Even if I have just 20 devices, cc2531 was giving some problems. Some devices would disconnect or would become slow. This zzh made a big difference. It works great. No problems so far.

Great product!

I've ordered it to replace my CC2531 used by ZigBee2MQTT. I've not tested it yet but based on the other reviews I'm sure that everything will go smoothly.

Producto de buena calidad.

El producto está muy bien y desde que lo tengo , la red ZigBee de mi home assistant no tiene fallos de conexión.
Aunque esperaba más intensidad en la señal. Vivo en un adosado con paredes de Pladur y eso hace que las señales inalámbricas tengan dificultades. Aunque no ha aumentado la intensidad, al no haber fallos en la conexión supongo que la calidad es buena .
Tengo conectados 26 dispositivos y dos routers a la red ZigBee

Perfect and easy to handle

I am very happy to have chosen this stick compared to other possibilities. Very easy to flash, documentation is extensive and intuitive. Price is fair and there is a nice sticker for your laptop included :)

Super !

I order it to replace my CC2531, and it's super awesome !
I'm using ZigBee2MQTT, with Docker, within a VM (proxmox), everything is recognised without any driver, working well with usb passthrough.
My ZigBee network is about 10-15 devices, I turned on availability.
And everything is running smoothly 😊

Really happy with the product und service

Works a lot better than those DIY CC2531 dongles. Shipping to Germany was fast. Can recommend to everyone

Great Upgrade

Great

Great device, i use it with zigbee2mqtt tot control nu lights and it works perfectly. Shipped and received quickly.

Very fast delivery to Belgium!!

Ordered the CC2652R, received one day later a message item was shipped. One week later arrived at home in Belgium
Flashing the device was a little bit difficult, probably my own fault. The Linux guide didn't work for me so after a few times I gave up and did it with a windows machine.
Using the stick as a zigbee2mqtt coordinator. Setup was done in less then 5 minutes after i flashed the device.
No communication with seller only received shipment notification but 7 days later I received the item so no extra communication needed.

A must-have for serious zigbee2mqtt home automation

I dipped my toe into the zigbee home automation integration with an inexpensive CC2531. That was a great start to figure out how "things" could work and what might be possible. However, when I reached around 15 devices, I started to notice sporadic longer delays and inexplainable instability issues. Since switching to the CC2652 in combination with my raspberry pi zero w to run zigbee2mqtt, I am much happier! The stick costs about 10x the cheap one, but in comparison to how much other home automation components are (RPi4 with SSD, wifi socket, homematic thermostat, etc.), this is certainly worth it!

Exactly what I expected

Not much to say, fast delivery, flashing exactly according given instructions, no problem since then. Seems more stable than previous CC2531 usb dongle.

Information for Dutch customers

Just buy this

I replaced all the lights in my house (40+) with ZigBee lights had attempted to do zigbee2mqtt with a 2531 stick and had constant drop outs, connection issues, and frequently the whole thing would crash - as a desperate last hope I ordered this stick. Completely fixed all of my issues, my ZigBee network runs better than I could possibly dream

Great Zigbee stick

Quality product

Seamless. It does what is on the tin. Instructions to flash are clear. Everything was pretty much seamless.

Excellent adapter and great support

I ordered 2 sticks in June, and they arrived quickly. Unfortunately I could try them last week, but I asked for help from Electrolama, because the windows programmer software didn't work perfectly. He wrote that I have sticks that are affected from the manufacturing issue, and two pieces of stick were posted immediately by Electrolama. I got them yesterday and they work perfectly.
Thanks for everything
John

Impossible to get it working on ESXi 6.5 Intel NUC i5-4250U

Great CC25xx upgrade

Fast shipping, good instructions and works much better than my old CC25XX dongle (e.g. had very limited range and capacity).

Excellent CC2351 replacement

I bought this as an upgrade from the CC2531 to use with Zigbee2MQTT firmware on a RPi4 running Home Assistant, and it's fantastic - there is a significant improvement in link quality with all sensors in the house. The installation was a little tricky - I ended up using the Texas Instruments Flash Programmer 2 software with the firmware from the Zigbee2MQTT repo, as for some reason the Python method wasn't working for me. Once it was flashed, I incremented the pan_id on the addon config by 1 and it worked. For the price of this thing I'm thoroughly impressed.

Best Zigbee adapter!

Works really well

10/10 Would buy lama again.

Everything went right, next day postage, got my package within 2 weeks (UK to Aus), easy firmware upgrade and boom Home Assistant picks it up (ZHA). Never had a more seamless experience in my life. Range is great, covers my whole apartment. 10/10 QT PCB and Sticker.

Excellent!

Excellent zigbee stick for home automation. I used to have a CC2531 with zigbee2mqtt, while I had stability issue with my network (60+devices). Now with this more powerful model, I have no stability issues anymore.

Awesome product, very easy to work with!

Had the zzh! working within a few minutes of unboxing, great documentation, awesome support and all my zigbee devices have been connecting solidly from the beginning, awesome work team!

Great stick, but more importantly a very professional seller

I needed this to handle a multitude of door and water sensors along with many plugs. Flashing for zigbeetomqtt is trivial especially if you’ve flashed its baby brother. It arrived very quickly in great shape even though shipping is slower these days. Best of all I didn’t get three emails making excuses and saying how broke he was and he even had to borrow money to buy the parts and here is a method to help cover the costs of a ‘reship’. Same base board, two different personalization, but this is the seller to use to actually get the product. I wish I had just waited till it was back in stock here the first time. Thank you!

works great

The stick came packaged in a cushioned envelope. I made the error of putting everything together before I flashed a binary on the device. My bad, but at least now I know that the case is quite sturdy ;-). Following the instructions to flash was easy enough, once I read them on the packaging. Thanks for this great product.

Serious seller.

After a pretty bad experience with another Tindie seller of the similar ZigBee stick, it was a pleasant surprise. Everything went well.
The only recommendation to this seller is that it should be nice to have the choice between zigbee2mqtt firmware already flashed.

Great product, great service

Product seems to work out fine so far. I have not yet made a direct comparision between my existing CC2531 and the new one - although performance seems to be snappier. Seller was helpful, and reached out to me after purchase. Cannot recommend the product/shop enough :-)

Great product

Perfect replacement for my CC2531. I have my zigbee network finally stable and reliable. Very happy.

A great little multiprotocol stick

Works exactly as described, was a breeze to get it running using Raspberry Pi 4. No problems with connectivity whatsoever. The form factor is great, the case is extremely easy to assemble (however, very difficult to disassemble :)). 10/10 would recommend.

I was disappointed.

The RF sticks come with no built-in functionality and the documentation is sparse and contradictory.

Very happy with zzh overall

Everything went very well, shipping was fast, the packaging was nice and there was also a small Lama sticker included :D The documentation for flashing the device from Electrolama was also great, basically for every common platform and not e.g. only for Windows. Thanks!

Great Seller and Communication

Great zigbee tool for homeassistant

I decide to use this device because is more stable never again disappear buttons or sensors and also I'm able to upgrade ikea and hue devices from hassio bye bye gateway.

It Works Flawless with Zigbee2MQTT

Well done product. It was easy to flash firmware from Zigbee2MQTT. It works flawless and has a medium network range.

Excellent for home automation

Perfect

Perfect product. Support in Zigbee2Mqtt is sufficient now with the latest firmware. Reception/LQI is not the main factor, but still it is better than with cc2531 equipped with antenna. Built quality is on professional level. Shipping fast. Communication excellent! In my opinion number one solution for open source based ZigBee networks. Thanks a lot!

Work as expected and good packaging

Nicely packed and work as expected.
Instructions are fairly straightforward and easy to understand.

Wonderful device, works fine with zigbee2mqtt

The quality of the product is fine. Shipping was fast. The documentation is easy to follow, to download the firmware and to make the device run. The integration with zigbee2mqtt was easy. I have to repair all the devices (12); the proccess was fast. Range is good, better than my previous CC2531 dongle (with external anntena). I can recommend the stick.

What can it do, and how

I bought the zzh! as an alternative to Phoscon Conbee II, which have a strange ui. But i dont know much about it. I hoped it had bluetooth, but havent found out yet. Home Assistant doesnt recognize it as a cc2652r, maybee because i had a cc31something before, and it didnt recognize the new stick.
Besides that, i love the antenna and case, which is included. But its new, so i hope its just a question of time, until i find more info about the konk firmware etc..

Works great

Much better than the standard CC2531, migration was painless, repairing *was* requred but all config remained the same.

I love it, switched last night from 2531 and it's awesome!

I bought the stick a couple of months back but it was sitting in my cupboard waiting for me to find some time until last night. I did something that wiped my entire zigbee network config on my Pi4... school boy error but after having to re-pair all my devices I decided it was time to move on and put the 2652 in production. The experience so far is awesome. Range is far better and most of all lights now turn on/off all at the same time. Before, with my 2531, you could see light go on/off in sequence and sometimes even a significant delay. Also when you accidentally turn the power off of a light, when you power them back on, it used to take about 15 seconds until the lights discover the coordinator, etc... before you can start manipulating them. Now, it's instant. It was worth going to be at 2 am last night :)

Good product, easy to setup and it works

The only downside is the occasional disconnects, I need to pug out the module and than back plug in for Zigbee2Mqtt to continue working.

Well constructed stick

Replaced my old Texas Instruments LaunchPad. No problems at all, documentation is spot on. Shipping was fast.

Awesome bit of kit

After the hiccup with a fake component (resolved beautifully and communicated perfectly), the stick works great and powers my home automation setup for about a month now, and does that just fine.

Great product

Using with home assistant and a raspberry Pi 4. Was simple to flash and set up with Zigbee2mqtt. Shipping was pretty reasonable speed even with COVID restrictions.

Works great

Fast shipping to the Netherlands. Works way better than the standard cc development stick. Better range and works well with zigbee2mqtt.

Very satisfied customer

Perfect

Great replacement for my CC2531. Much more powerful, and improved range. I like the zzh. I'm looking forward for the next version with an additional PA.

So far its great

1) The quality of what I was sent was great. The casing is simple but nice, much smaller than it looks in the photos.
2) Shipping overseas went as smoothly as you could imagine
3) The documentation is definitely enough for two scenarios: 1) everything goes smoothly or 2) you have more than a basic understanding of every step. It turned out that it did not go smoothly for me and I didn't have a deep enough understanding to troubleshoot on my own.
4) The Seller was extremely helpful in getting me set up and was extremely pleasant to deal with.
5) Also, this product is quite popular with the Home Assistant crowd so if there is something that is beyond the scope of what the seller can help you with the Home Assistant Discord and Community is EXTREMELY helpful - if you are also using Home Assistant. I can't speak to other platforms.
6) If this seller made other things that I need/want I would definitely buy from them again - as this was a really good experience.
7 )Now that my ZZH is up and running my connections are strong (LQI's generally between 85-110 so far) this is really an excellent product and it is a major upgrade from my CC2531 and was much easier to deal with than the Sonoff Zigbee Bridge that wouldnt flash the Zigbee firmware.

Big improvement

Awesome product and service

Awesome product from awesome guy

Does what it says on the tin. Being able to flash the CC2652R with such ease makes things so much easier. Would buy again from electrolama.

Great product, tnx!

I ordered this last week after playing around with a CC2531 for some weeks. This one seems to be much better and more powerful. Flashing Zigbee2MQTT might be a little bit difficult if you're not that experienced with Linux. I attached a bigger Chinese 8dbi antenna and all is working perfect. The item arrived in Belgium within one week. Tnx!

Awesome stick, fantastic service

Using zigbee2mqtt? This is a no brainer!

Great solid product including skilled and helpful support

Great product made by an awesome developer

The ZZH! Is a great product with a genuine development team behind it. The device is manufactured to a very high standard and even when one batch had a problem which was down to the manufacturer being dishonest, the developer behind ZZH! Let everyone know for transparency.

Great product. My Zigbee never has never been so stable.

I have a moderately large zigbee network - 6 permanent routers, a couple that come and go (lamps on normal switches), and about 40 or so other devices. Previously I was always finding devices would drop off the network after a couple of weeks of stability, and the routers would have to be placed fairly close to the coordinator. With zzh, everything has been absolutely rock solid since it was first set up. Being able to flash the device without an external programmer is a significant benefit as well. I was back up and running with all devices re-paired in way less than an hour. I’ve been able to place the routers where it’s convenient rather than where I can get a signal, and all of them are able to connect directly to the coordinator, which wasn’t possible before.

Professional shop, boards solid and working like charm

perfect for zigbee2mqtt

Had the CC2531 adapter with a lot of devices but devices were randomly falling of the network. so the network was not stable. also pairing new devices was a nightmare after a number of devices - no log at all and i had to reflash the adapter to make it happen again.
since the new zzh! adapter i had zero problems and the network is super stable. pairing new devices work all the time. everything is rock solid and i am glad i ordered the stick.

A seller who stands behind his product

I appreciate the proactive communication from the seller regarding problems with a particular batch and plans to address that issue. In addition, he sent a replacement at no additional cost for a shipment that never arrived. Replacement arrived quickly by the standards of international shipping.

Excellent build quality

(Really bad reception) New device is working as expected!

Great device!

Work like a charm

Works perfectly, was shipped quickly and communication with seller was excellent! Case is a tight fit and looks solid. If you intend to flash the stick often, it might be best to not attach the case.

Great product, great documentation

Shipped quickly and well packaged, documentation was detailed and covered all the items needed to get up and running quickly.

Easy Setup and Works Great
