Noticed bug? with G400 doorbell - face detection disables on doorbell restart

n1976jmk · April 14, 2026, 11:32am

I wanted to please notify the Aqara developers, I have my G400 on the latest firmware (4.5.20_0026). When the doorbell is restarted via the Aqara iOS app or power physically removed, then the ‘face detection’ is disabled. I normally have it enabled -settings-ai detection-face detection. But if I restart it or remove power then face detection is disabled every time and I have to go enable it each time afterwards.

Thanks!
