A few months ago my Xiaomi stuff just stopped working completely. I’m sure it corresponded with a hass update but I wasn’t checking frequently and don’t know exactly when it stopped working. Fast foward to today, I reinstalled hass fresh ( 0.113.2 ), running docker on synology. Using the Xiaomi Miio integration I was able to successfully link my hub (version 3, I believe) but the integration is ONLY picking up my temp and humidity sensors. I have at least 10 or 15 door/window sensors that I can see through the Xiaomi app but Home Assistant is not registering them. I’ve had them working in the past and so I know they are compatible. Anyone have any ideas?
but Xiaomi made it impossible with more recent firmware or app versions. I am not 100% which is responsible.
The Miio integration uses the token and that is more easily getable.
So if you happen to have the key for your gateway, then use the Aqara integration to connect. Else, as you will see from that thread I linked to, it’s not clear how you can get access to the other sensors…
