For those that want their Wyze cams 100% local (with RTSP), you can use wz_mini_hacks[0]. I've set up v2 and v3 cams using this, and they've never touched the internet or wyze app.
I've use the official RTSP firmware in the past on some v2 cams, but I remember it having some problems and not being as good as this solution.
