yes. You have to go into the Eufy mobile app and enable RTSP for each camera you have registered. Assign the camera a static IP and add a password there. Then use that in your frigate config yaml to setup the stream. Including go2rtc.

Your go2rtc url should look something like this and it will display that url in the camera configuration in the app itself.

rtsp://cameraname:password@<ip address>/live0

Yes, this answer is correct. Although I use tapo cameras now, I played with eufy cameras in the beginning, and it seemed to have worked just as well.
