Multiple Sonoff Zigbee Bridge?

WarLion · January 5, 2021, 4:59pm

Hi guys i need your experience , i had a Sonoff Zigbee Bridge already flash it with tasmota and working great , i need of another Coordinator in my setup , and i was thinking on buying the CC2531 ZigBee USB Wireless Module , but i find that is cheaper to buy a new sonoff zbbridge in my country , if i need it to be able to use as a coordinator do i need to flash it with tasmota as well? or i can use it from the box ,

any help will be very appreciated

The CC2531 chip is not of the type that works with Tasmota I believe. Also, you can only have a single zigbee coordinator per zigbee network. So if you want multiple zigbee network, you have to come up with a design that allows for that. I believe you can only have one ZHA zigbee network per Home Assistant server. So ways to get multiple zigbee networks on a single Home Assistant server would be use ZHA and Zigbee2Mqtt and or Hue and or Ikea … But now you have multiple methods of zigbee management to deal with. You might see if you could run multiple instances of Zigbee2Mqtt, that would allow multple CC2531’s to run as coordinators on different zigbee networks. But Zigbee2Mqtt does not support the Sonoff Bridge… Maybe there is a way to solve your problem with a single ZHA instance on your HA and use routers to extend this network. Your CC2531 would act as a router in this design I believe. You would just plug it into a USB wall wart, place it in the far location you want better coverage for and add it to the ZHA network. Then add your additional ‘far’ end devices ‘via’ this router.

Good hunting!

The instructional videos that I have watched where the Sonoff Zigbee Bridge is flashed with Tasmota, the Zigbee is either flashed to work with either Home Assistant or Zigbee2Mqtt but not both. Every video I have watched has shown how to flash the Zigbee2MQTT option.

Well, I looked the zigbee2mqtt web site and still do not see any support for the Tasmota Sonoff Zigbee device, seems like some type of disconnect here:

I don’t know what video’s you watched, the Sonoff Zigbee bridge flashed with Tasmota firmware works with ZHA or Zigbee2Tasmota. Zigbee2MQTT does not support the bridge.
Since both Zigbee2Tasmota and Zigbee2MQTT use MQTT to talk to HA, I think you are confusing both.
