Sonoff ZBBridge WiFi to Zigbee gateway was introduced in April 2020, and a few months later got support for Tasmota ESP8266 firmware and Gecko firmware for either Home Assistant or Zigbee2MQTT support.
But there’s now a new Tasmota firmware that converts Sonoff ZBBridge into a Zigbee router (a.k.a. Zigbee Signal Repeater or Zigbee Range Expender) following a request on Tastoma Github’s issue tracker from last year.
The firmware, unofficial yet signed, was released a few days ago by xsp1989 Github’s user with a link to the firmware on Google Drive. Digiblur successfully tried it out on its own Sonoff Zigbee bridge and published the instructions. Assuming you already have Tasmota flashed to the device, switching to the router software is basically a firmware upgrade from the Tasmota web interface.
Once the update is complete, you’ll still need to access the console in Tasmota in order to run a command to enable support in the GUI, as well as configure the reset button for the pairing procedure.

And that’s basically it. Zigbee2MQTT (Z2M) users will have to download silabs.js file, add it to their Z2M config folder, and add the custom converter to the configuration, but this will not be necessary for too long since the device will probably be added to Z2M builds. Check out Digiblur instructions for the full details.
CNX Software have been told that while ITead Sonoff ZBBridge with Tasmota is relatively popular as a remote Zigbee Coordinator for Home Assistant’s ZHA and Zigbee2MQTT. it does have its issues with unstable WiFi in some cases, so it may be better to use it as a Zigbee Router, and rely on SONOFF Zigbee 3.0 USB Dongle Plus as a Zigbee coordinator.
