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

For zzh! CC2652R Multiprotocol RF Stick

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)

Tamas | Jan. 18, 2021

Excellent communication and shipping time.

For zzh! CC2652R Multiprotocol RF Stick

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

Excellent device, great price and a fantastic seller

For zzh! CC2652R Multiprotocol RF Stick

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.

Jaap | Jan. 11, 2021

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

For zzh! CC2652R Multiprotocol RF Stick

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.

Ricardo | Jan. 8, 2021

overall the experience was good

For zzh! CC2652R Multiprotocol RF Stick

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

Mario | Jan. 8, 2021

really good service and good device, thanks!

For zzh! CC2652R Multiprotocol RF Stick

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

Finally - no glitches...

For zzh! CC2652R Multiprotocol RF Stick

I have been using a Conbee stick for quite some time for home automation and every now and then a light/socket/switch would lose connection to the network and stop working (until I have done a power-off/power-on). This is extremely annoying and not a good thing for family acceptance of home automation....

After switching to this stick all these problems seems to be gone and it also seems to be "snappier" in response!

I am very satisfied with this stick.

Remko | Jan. 6, 2021

Seems to work great, fast and range is good.

For zzh! CC2652R Multiprotocol RF Stick

PostNL delayed the package for about 4 weeks, no blame to Electrolama, he even send us a mail about the problems with PostNL.

Just tested with 24 devices it seems to work more responsive and a good range.

James | Jan. 6, 2021

Better than CC2531

For zzh! CC2652R Multiprotocol RF Stick

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

Baptiste | Jan. 6, 2021

Easy to setup - great performances

For zzh! CC2652R Multiprotocol RF Stick

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.

Jonathan | Jan. 5, 2021

Just great!

For zzh! CC2652R Multiprotocol RF Stick

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

Raivis | Dec. 27, 2020

Very usefull and nice

For zzh! CC2652R Multiprotocol RF Stick

Great little thing, works excellent.

The only hiccup was with installing the firmware. On first attempt it was not clear to me that I have to put the device in flashing mode (even tho it was mentioned in the documentation). With little tinkering I understood that the stick is not empty, but has firmware that blinks the led and so I need to set it to flush mode to get proper firmware on it.

A bit of tinkering and all was solved. Works excellent!

Wojtek | Dec. 25, 2020

Does the job!

For zzh! CC2652R Multiprotocol RF Stick

I had a CC2531 stick that was working fine but I read all the amazing reviews on the zzh so I wanted to give it a try.

It was easy to flash. It works. All my devices could be paired.

This is what I expected from it and I am very happy. Having only 8 devices, I cannot comment about how it runs under load, some of them are quite far away and they are reachable (they were also with the stick).

What really set it apart for me was how easy it was to flash. No need for debugger devices like for the CC2531, just plug it in in flash mode and you are done.

I recommended it to a friend that was getting into Zigbee.

Mikko | Dec. 25, 2020

Quick delivery

For zzh! CC2652R Multiprotocol RF Stick

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

Андрей | Dec. 25, 2020

Хорошее качество связи и стабильность работы

For zzh! CC2652R Multiprotocol RF Stick

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.

Artsem | Dec. 25, 2020

Cool device for my smart home system

For zzh! CC2652R Multiprotocol RF Stick

I was upgrading from cc2531, this stick is completely next level. I migrated yesterday, but I can see significant increase of network range, link quality values are twice better. Stick itself is well made, as its case and default antena.
Packaging was not very secure, mine was badly damaged, i've opened it with one finger, but device is really smal, so no harm done.
Shipping wasnt too fast. One month to Belarus, but this have nothing to do with seller.

Highly satisfied with product itself!

Aaron | Dec. 23, 2020

Good product, excellent communication

For zzh! CC2652R Multiprotocol RF Stick

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.

Robert | Dec. 13, 2020

Great device and nice tinkering experience

For zzh! CC2652R Multiprotocol RF Stick

I ordered 4 December an it was delivered in the Netherlands at 10 December. Including sticker and candy!
I used tracked shipping due to the warning given on the website.

*extra tip to the already great documentation in zzh shop is to use numbered chapters to seperate the topics*
Before I started flashing and adding the device, I created a cut-and-pasted manual for myself.
The website is full of documentation and you need to read it carefully because all chapter names seem to be equally inportant and the same 'level'.
For multiple steps you need more sites so prepare a bit in advance.
Choosing your tool suite also has to do with what you have around. I wanted to build and flash straight on the target platform (raspPi3 with Domoticz) because it had Python3 on it already so I used something like this:
1. Check Drivers for CH340
2.Prepare Flashing using BSL
2.1 Choose Linux documentation
2.1.1 Download and extract cc2538-bsl
2.1.2 Install required dependencies
2.1.3 Flash zzh firmware
3. Install Zigbee2mqtt on Pi
4. Install Zigbee2MQTT plugin for Domoticz on Pi

The dongle picked up my Silvercrest wall socket almost immediately (10 meters apart through 2 solid concrete slab floors) so I'm very happy with the range and speed). I'll be able to extend, mix and use devices in the future and I am very happy with the product.

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

The perfect Zigbee adapter for Zigbee2mqtt?

For zzh! CC2652R Multiprotocol RF Stick

I started like many others do, with a Texas Instruments CC2531 on a USB stick, and that was good, but it crashed a lot and forced me to regularly reflash it.

I then moved to the LAUNCHXL-CC26X2R1 and that showed to be a real winner (especially after flashing the 20201113 firmware) but this is a huge board, even bigger than my Nanopi M4V2 SBC that I have it connected to!

Then I saw the zzh!, which is the same chip as the one I was using (and same firmware) so I decided to get me one of these!

Moving from one to the other was just a matter of changing a few configuration settings, as it completely restored the automatic backup from one adapter to the other with no issues at all!

The only complaint I have is of the time it took from the confirmation of postage to actually receiving the item, but overall, I'm quite happy with this adapter and I do recommend it to everyone using Zigbee2mqtt!

Erinc | Dec. 8, 2020

Amazing Product

For zzh! CC2652R Multiprotocol RF Stick

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.

Peter | Dec. 6, 2020

Works fine as zigbee coordinator

For zzh! CC2652R Multiprotocol RF Stick

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.

Daniel | Dec. 4, 2020

Great product for zigbee2mqtt and Home Assistant

For zzh! CC2652R Multiprotocol RF Stick

Well put together stick, using as a coordinator for zigbee2mqtt.io hooked into home assistant core.

I've Ikea / Hue lights, Ikea blinds, xiaomi sensors and some generic smartplugs connected up, over 30 devices in all, no lag and great performance.

Using a couple of ikea range extenders which also work well to ensure there is good zigbee mesh coverage.

Highly recommended

Michal | Dec. 1, 2020

Excellent upgrade from CC2531

For zzh! CC2652R Multiprotocol RF Stick

Migration from CC2531 was very smooth and with my huge mesh it return the expected stability back to normal.
I also noticed better signal range.
Still sometimes network is slow to respond or loses some packets but it might be SW problem.

Overall great improvement and I would recommend it to everyone.

Niels Rune | Nov. 28, 2020

Recommended product and seller

For zzh! CC2652R Multiprotocol RF Stick

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.

Ole Alfred | Nov. 26, 2020

Good product, terrible shipping

For zzh! CC2652R Multiprotocol RF Stick

Okay, so first thing first. I'm really happy with the product, it seems to be a good device and the documentation(online) is good. Got good directions about how to flash, which firmware to use etc. And device just works with both zigbee2mqtt, and home assistant. And others too, I'm sure.

However, the shipping was a slight hiccup(might/might not be related to covid-19), the shipment was at London Central MC 10 days, before being flown out of UK. With free shipping this is expected, but when shipping cost 14 USD, I think it should be prioritized.

Anyway, I got the item and all in all I'm pleased. Thank you!

Response from Electrolama | Nov. 26, 2020

Happy to hear that zzh is working well for you!

Regarding shipping, as you've rightly guessed the pandemic is indeed causing havoc with global postal services and everything is moving a lot slower than usual.

We are all very used to free or unsustainably cheap shipping out of the likes of Aliexpress sellers but the reality of it is that without the preferential pricing you can get at significant volumes, Royal Mail International services are expensive. While I have been trying to get better rates, it seems like even the accounts teams are overwhelmed right now as I have been "on hold" for weeks now. When this is all set up, eventually, I hope to be able to offer cheaper shipping options.

Matt | Nov. 24, 2020

Great product, easy to flash, fantastic range.

For zzh! CC2652R Multiprotocol RF Stick

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

For zzh! CC2652R Multiprotocol RF Stick

Sadly I couldn’t get this to work reliably.

I managed to pair one device, but then when I removed it I couldn’t re-add it or pair any more devices.

I think it would help to provide a step by step sequence of HomeAssistant setup with direct links to the correct firmware to install and how to do it.

Also for debugging, a way to completely remove all stored data On the hardware and HA settings. It seemed to be remembering old devices but I couldn’t work out where.

I am confident that the hardware is good, and the firmware/HA zippy code will improve over time. So I’ll try it again in a few months.

But for now I feel I’ve already wasted too much of my life trying to pair Bluetooth devices.

Small note: The plastic shell Is hard to remove and gets in the way of the button which you sometimes need to press. So would recommend not fitting that until fully happy that it’s all working.

Edit 1/12/2020: sorry I meant zigbee not Bluetooth.

It’s now working reasonably well. My tip is to restart homeassistant if you remove a device from the network and want to re-add it. I assume the reliability and interface will improve over time.

Some of my xiaomi door sensors have dropped off the network without any apparent reason but the rest seems ok.

Thanks?

Response from Electrolama | Nov. 26, 2020

Sorry to hear you've been having trouble with pairing devices Dave, if you'd like to have a chat about a few things we can look at please feel free to drop me an email at support@electrolama.com (I can't actually see email addresses or full names on Tindie reviews otherwise I would have pinged you directly).

Re: Bluetooth, while the CC2652 chip used is indeed a multi-protocol device, the standard and ubiquitous Zigbee coordinator firmware used does not actually support it so that is why you wouldn't have been able to pair Bluetooth devices.

Tim | Nov. 18, 2020

Beautiful Little Device

For zzh! CC2652R Multiprotocol RF Stick

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.

Jerome | Nov. 17, 2020

Good product and good seller !

For zzh! CC2652R Multiprotocol RF Stick

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 !

Dave | Nov. 13, 2020

Very fast delivery to Belgium!!

For zzh! CC2652R Multiprotocol RF Stick

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.
