Best Overall Zigbee Stick

Wifi, no. wired ethernet yes.

I understand differences between wifi and ethernet, but is there anything not obvious in choosing coordinator connected to HA via wifi?
I mean, the most important thing is to ensure zigbee network stability. connection to HA is secondary and I believe local wifi and ethernet both can be very close to each other reliability-wise

Every time I see it mentioned, people say “no way, don’t do it”. I haven’t investigated. But I do trust the advice on this page Supported Adapters | Zigbee2MQTT

Well 25 $ for a router seems high: which is the advantage between a router, and say, a light bulb places conveniently to be used as router?

Any other (cheap) router that you recommend to put here and there where you don’t want the hassle to install a light/switch zigbee device?

unreliability of WiFi, I would definetely NOT go that route


Same for ZHA and Zigbee2MQTT. Remote adapters work OK over wired Ethernet but not ok over Wi-Fi

I would like to thank you for the advice. Yesterday my Sonoff Zigbee 3.0 USB Dongle has arrived and today I have successfully migrated my whole network to it. It works phenomenal compared to Conbee II stick. @Tamsy Thank you a lot for the reccomendation. :star_struck: You made my life a lot easier :pray:

:thinking: The only problem which I still have (and it seem unresolveable) is that my IKEA Tradfri Shortcut Buttons not connecting to the network. Well, in theory they connect, but they would become unavailable in a couple of seconds after connection.

But do they generate an event?

Did you get the P or the new E version ?

I’ve got the Sonoff Zigbee 3.0 USB Dongle Plus and have about 25 sensors in my house. But only 22 are working. Even new ones only work for some minutes and then they lose connection.
But Zigbee should support approx. 250 devices, shouldn’t it?
Is this dongle the problem? Can I attached a second one?

if u r sure (22/25), u can add a second one as a router. this worked just fine for me.

Most mains devices are routers.

@jtihonov how is your sonoff stick after some time. I am in the same boat, I have conbee + deconz and it is so unreliable.

Which version of the Sonoff stick?
I experienced a similar issue when using a Sonoff ZBDongle-E (together with Z2M). It’s still listed as experimental on the Z2M homepage so I got myself a Sonoff ZBDongle-P instead (also flashed it to the latest SW). Haven’t had any more issues after that.

I use the P version. Never had any issues. I think I added it for about 2 years now

Unfortunately not possible like that, at least not at with Zigbee 3.0 and previous Zigbee standards.

The ZHA integration does at this point not support multiple Zigbee Coordinator adapters at the same time and you can unfortunately not either at this point have multiple ZHA integration components instances installed and running inside a single Home Assistant core instance at the same time.

See questions and answers as well as suggested workarounds like installing a Zigbee2MQTT instance at the remote location just for any distantly located devices → Multiple ZHA integrations possible?

The best solution is however just to build only one big Zigbee network with more and stronger Zigbee Router devices (to one Zigbee Coordinator inside a single Zigbee gateway instanse), see → Zigbee networks: how to guide for avoiding interference and optimize for getting better range + coverage

Again, Zigbee uses mesh networking topology, which means that most mains-powered devices are a “Zigbee Router” that can act as a signal repeater and range extended by transmitting data over long distances by passing data messages through the Zigbee network mesh of intermediate devices to reach more distant Zigbee devices. Thus to have a healthy Zigbee network, you need many Zigbee Router devices relatively close to each other in order to achieve good coverage and range.

Any battery-powered device will be a “Zigbee End Device” which means that they do not route/repeat messages and thus does not contribute to routing to help extend the range of the Zigbee network mesh.


So if you plug the second sonoff on a power source like an electric plug adapter it will automatically repeat the signal to the one plugged on your HA server (for my part Rpi4) ? Or does it need some tweak or config ?

I think I’m going to buy a pair of P version if yes

Needs to be flashed with router firmware and then paired like any other zigbee device.

Yes, both the ZBDongle-E and ZBDongle-P can be repurposed/converted into dedicated Zigbee repeaters/extenders by flashing a respektive ”Zigbee Router” firmware, after that they just need power via a USB-changer and be paired/joined just like any other device.

Very good. Forgot about it’s existance. Zero fail.
