I have mainly Xiaomi sensors I wanted to get rid of the bulky Xiaomi Hub and bought a Sonoff ZBBridge.
I successfully added the door sensors, but when I put the Motion Sensors in binding mode they do not show up.
I tried searching for information I found that the Sonoff uses Zigbee 3.0 but unable to find anything on what version of zigbee the xiaomi motion sensor uses as to whether it is compatible. The door sensors and motion sensors are the Mijia versions for the hub 2.
