@BKeyport i didn’t want to program for every webcam out there, so I found a system level library that does it

the motion project… it can do all kinds of video/pics on motion…
https://github.com/Motion-Project/motion

but it also can call a script/program when motion starts/ends… so I wrote a MM screensaver module that watches for the events from the external motion module… now my TV’s don’t support any cool way to turn off the display, so I hide all the modules… and show later on motion…

(and I use this same approach on a different smart-mirror that I found before MM)…
