I’m not sure if this solution are going to give me the access to the information of the associated sensors, because this is my first objective. I knew that Air companion is an unsupported device, but I thought that only the climate control, not the Gateway function
The zigbee part / gateway function of the Xiaomi Air Conditioning Companion isn’t supported by Home Assistant (xiaomi_aqara component) right now. The MiHome app provides a key for a local network protocol since december 2017 but the API specifications are unknown so far.
The custom component just provides a climate device to control a attached air conditioner by infrared.
