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 😊

Producto de buena calidad.

For zzh! CC2652R Multiprotocol RF Stick

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

Great product!

For zzh! CC2652R Multiprotocol RF Stick

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.

A must-have for serious zigbee2mqtt home automation

For zzh! CC2652R Multiprotocol RF Stick

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!

Just buy this

For zzh! CC2652R Multiprotocol RF Stick

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

For zzh! CC2652R Multiprotocol RF Stick

Great replacement for my CC2531 to use with Zigbee2Mqtt and Home Assistant (worth noting it does support the native Home Assistant ZHA integration too).

Flashing with the firmware was straightforward with just plugging it in and running a command or 2.

Works really well

For zzh! CC2652R Multiprotocol RF Stick

Bought this to bring more Zigbee devices into the home that are not supported by the other hubs that I have, plus also bring different functionality to those that are supported but limited.. It works really well. Attached it to an old raspberry PI, flashed the firmware for Zigbee2MQTT and then installed Zigbee2MQTT on that device. On a separate machine I already have Home Assistant running plus an MQTT server.

So far in my 240sq meter house, with one Tradfri repeater I haven't had any problems with signal, and it seems very fast at responding. Totally recommend it.

A great little multiprotocol stick

For zzh! CC2652R Multiprotocol RF 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.

It Works Flawless with Zigbee2MQTT

For zzh! CC2652R Multiprotocol RF Stick

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

Work as expected and good packaging

For zzh! CC2652R Multiprotocol RF Stick

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

Good product, easy to setup and it works

For zzh! CC2652R Multiprotocol RF Stick

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

Adam | Sept. 29, 2020

Great product

For zzh! CC2652R Multiprotocol RF Stick

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.

So far its great

For zzh! CC2652R Multiprotocol RF Stick

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.

A seller who stands behind his product

For zzh! CC2652R Multiprotocol RF Stick

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

For zzh! CC2652R Multiprotocol RF Stick

Even though I managed to get one of the faulty devices from the latest batch, I would like to review the build quality and how professionally Omer has handled the unfortunate situation with the few devices that had a problem. I will get my free replacement device any day now.

The only sad part was that shipping to Sweden took two weeks even though Omer shipped it quickly...

Friends with the ZZH describes the performance as awesome! I would recommend anyone to do business with Omer.

perfect for zigbee2mqtt

For zzh! CC2652R Multiprotocol RF Stick

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.

Martin | July 2, 2020

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

For zzh! CC2652R Multiprotocol RF Stick

(I bought this zzh! to replace my CC2531. The CC2531 has not the best reception but the main problem is the very limited number of devices that it handles. So I decided to buy a CC2652 which should be better. But the zzh! is even worse considering the reception. I tried to get it working - changed the position, changed direction of the antenna but nothing improved reception. Finally I gave up and switched back to the CC2531. I am really disappointed. I cannot recommend this device, especially for such a high price.)

I got a new device for free because the old one had a faulty part - the new one meets my expectations. I really recommend this tiny thing. In the meantime I used an original TI- Board LAUNCHXL-CC26X2R1 which is a lot bigger, more expensive and has no advantages above the zzh! as far as I can see (at least for my usecase as a zigbee coordinator).

Thank you for your support, Omer!

Hi Martin,

Sorry to hear you're having trouble with zzh.

I am investigating what appears to be a manufacturing issue with some of the zzh boards shipped in the last batch (sold on Tindie 20/06/2020) with users reporting bad RF performance just like you have. Everyone who bought a unit that might be affected has been notified and I will be providing updates and a solution as soon as I possibly can.

I hope you'll give zzh another go once we formulate a solution as it should perform significantly better than what you've seen so far!
