SONOFF Universal Zigbee 3.0 USB Dongle Plus Gateway with Antenna for Home Assistant, IoBroker, Zigbee2MQTT

Be warned that Geeky products attract geeky reviews - like this one ! :-)I wanted to automate my Garden workshop lights, as its a steep uphill jog from there to the house in the hissing rain only to discover that, in your haste to get out of the rain, you left the bleeping lights on!Having researched various methods to achieve this, ZigBee seemed to be the easiest to setup even if the range was constrained when compared to similar wireless connections like Wi-Fi.So I bought my first Zigbee light switch and Sonoff dongle to try and make it happen.The dongle plugged straight into my home assistant server (running as a VMWare based virtual machine situated in my attic some 200 feet away and 70-100 ft uphill from my workshop) and was immediately recognised by Home assistant as a Zigbee Co-ordinator.Unfortunately for me though, when I fitted the ZigBee light switch, the attic dongle couldn't see it as there were thick roof slates and two VERY thick breeze block walls in our terraced hillside garden separating them. The light switch was tucked away beneath the final wall.I feared with all the Wi-Fi and bluetooth traffic on the same radio channels (curse of living on a hilltop) that my proposed solution was a non-starter.But being a hobby / professional Linux geek, I had a google and a poke around on the GitHub website to discover that the same Sonoff dongles could be re-flashed with third party firmware that turns them into stand alone ZigBee Repeaters / Routers.Once flashed, all they required was a 5V USB power source (I used an old Samsung phone charger) and they work as a ZigBee range extender.**Fair warning** - building and setting up the software packages to reflash these devices is not for novices. But once built, you have a tool that can flash as many of these dongles as you need (be careful as there are 2 hardware dongle variants too) . So I bought a second dongle , and flashed it.Having flashed it, I took it down the workshop and plugged it into the phone charger into a mains socket on the the "downhill" wall so that it had a better view of the attic about 150 feet away and 75 feet higher in elevation above it.Within seconds home assistant recognised the existence of the shed router dongle and began talking to it. A minute or so later Home assistant reported the light switch as available so I completed the integration.I could now not only turn my workshop lights on and off from anywhere in the world (!), but use the shed lights as "soft" lighting for our deck above it. and all was well.That was... until our neighbours Wi-Fi decided to move channel autonomously (it does that a LOT) ! :-(The HAN (Home Area Network) tried to reconfigure itself , but at this point the distances involved with the roof slates and the level of Wi-Fi interference made the light on/off function a 1 in 3-4 chance of getting through.I purchased a 3rd ZigBee dongle, flashed it as a router, and installed it under my eaves using another old mobile phone power supply and a USB extension cable. I pushed the antenna out through one of the attic vents built into the eaves, and wrapped the antenna joints in self-amalgam tape for waterproofing.Instantly all devices linked up together solidly! and there has not been a single issue since (no matter what neighbour's Wi-Fi tries) . The attached pic shows the topography of the network auto generated in Home Assistant. I now have saturation coverage of my home and gardens so VERY pleased with the setup.Since that snapshot was taken I have added many other ZigBee devices without a hitch.So to my scoring:VALUE FOR MONEYAs a plug and play ZigBee co-ordinator - 5 stars - no quibbles. plugged it in and boom! it integrated100%As a ZigBee Router once flashed , again 5 stars - zero failures , no wobbles , nothing - just works!EASE OF INSTALLATION:It would be nice if Sonoff had made it easier to reflash the device without extensive Linux knowledge. Perhaps a windows app for the not-so-geeky everyman?Hmm...I think one point off for relying on third party software when it has potential to double sales of your product!EASE OF USE:In both co-ordinator mode and router mode (once flashed) you plug it in and it works thus far error freetherefore I have to give it 5 stars.I hope you found this interesting if a bit geeky - but thats ZigBee for you.Thanks for reading!

While it may lack some advanced features of pricier models, its performance and connectivity make it a fantastic value for money.

Perfect little Zigbee dongle! I needed a new one after accidentally dropping my server, which smashed directly into my old adapter, destroying it completely. This device worked perfectly with Home Assistant—no need to change the firmware—and the range is great. The only downside is that the USB is quite wide, so you might not be able to fit another USB device side by side (I can’t).

I already have an Ethernet Zigbee Coordinator within my home to control and monitor smart devices, I've purchased this Sonoff Zigbee dongle to be able to extend the network a little further and this fits the bill perfectly.It was a straightforward process to flash the Sonoff dongle with router firmware to enable it to act as a Zigbee repeater. Instruction and links are available elsewhere. As soon as I paired this with my existing network intermittent connection issues and Zigbee low signal areas were successfully dealt with.OK most of the ease was provided by Home Assistant. Thanks to this open source package my new USB Zigbee controller was in and replaced the old controller in about 15-20 minutes. Better range than the old one, the reason for buying. Nothing went wrong and the whole experience was very good.The packaging was sufficient and all paper/cardboard. The stick was in excellent condition once removed from the packet. Plugged in and worked first time. No tears or traumas. Documentation is limited in the packet, I did not need it. If you do the there is plenty of information on the internet.This is a recommended controller with Home Assistant and from this first days experience i would recommend it. There are cheaper options but this fulfils all requirements and if range is an issue it appears to be very good. I say this realising the limits of Zigbee and my very none scientific test, I managed to reach an unreachable sensor.
