yeah... I know about yi-hack.
The thing is, I've installed some of them at my parents house.
Therefore, I'm writing a bash-script (should work for all cameras and devices) where the device opens up a reverse SSH tunnel to a public server, and let's one access the cameras (RTSP) from frigate, even if they're located elsewhere.
I've bought a bunch of Yi Home 1080s a few years back for cheap... I think it was 13 bucks each.
