Tasmota and Zigbee2mqtt developers started hacking on new Sonoff Zigbee Bridge

Configuration Zigbee

Sonoff ZBBridge by ITead is a new inexpensive Sonoff branded Zigbee 3.0 to WiFi Bridge/Gateway/Hub

It contains an ESP8266 WiFi MCU and a very powerful Silicon Labs MCU with Zigbee 3.0 radio based on EFR32MG21 (EFR32 Mighty Gecko) from Silicon Labs.

Tasmota running on the ESP8266 inside it could possibly either it acts as Zigbee gateway/hub itself or possibly only acts as a networked serial/UART server for remote pass-through access to third-party software like Zigbee2mqtt or ZHA (Zigpy and Bellows).

It’s very early days however I think that will be interesting to follow development of that hacking effort

FYI, Tasmota developers has now released a ”tasmota-zbbridge” firmware which can be flashed onto the Sonoff ZBBridge so that that WiFi Zigbee bridge can then be used as a Zigbee coordinator adapter for ZHA in Home Assistant. @digiblur posted a step-by-step guide on his blog here:

FYI, digiblurDIY has now posted updated video with step-by-step simplified guide for solderless flashing

Followed it and working, but, any way it can work with zigbee2mqtt? Instead of ZHA

Not currently because Zigbee2MQTT (which relies on zigbee-herdsman) does not yet support the EZSP serial protocol that Silicon Labs Zigbee adapters uses, and there is no news that some one is working on making that happen
