I’m glad you got the video working!
I worked with someone else (@Sakari) to try and get the motion detection working on their Tapo camera, but we were unsuccessful. I was even looking at buying one so I could test here. They aren’t very expensive, but the shipping to the U.S. was more than the camera itself unfortunately!
If you have lots of time and patience, I’m happy to continue trying to figure out the problem. You’d need to be able to download and run the CLI so we could get logs.
