I have a lot of stability issues with my Aqara door sensor. Disconnects frequently. I think this could be a problem with the router, because I have a dual WiFi band and the documentation says that Aqara only works on 2.4. Is there a good alternative? My only use of the Aqara is for the door sensor to turn on my pantry switch when it’s open and for the motion sensor in my garage to turn on the light.
