Would be really happy if some of the Developers here can integrate the cameras. Recently I’m experimenting a lot with Home Assistant (connected to Homey via MQTT), they have an unofficial Integration which isn’t working great either. They also discussed it over here https://community.home-assistant.io/t/eufy-camera-integration/121758/150
Someone also mentioned that they changed a few things in the background not so long ago.
The biggest problem I see with the Eufy Cam products is the missing connection to other Smart Home products.
I don’t have the door bell! I only have the battery powered security cameras which already support RTSP. I tried to add them to my Synology Surveillance. Connecting the camera was possible but unfortunately RTSP support is extremly unstable (I wouldn’t even call it Beta).
In any case, Homey doesn’t support RTSP so the same applies. If the camera’s support snapshotting though HTTP(S), they should already be supported by Homey.
