Third, I bought a couple of Wyze cams before I decided to go the HA route and since discovered that integration is not possible. I want more cameras - would appreciate suggestions.
As for wyze cams, also have two and using the rtsp firmware(https://support.wyze.com/hc/en-us/articles/360026245231-Wyze-Cam-RTSP) with the motioneye addon and works as needed.
+1 for rtsp firmware. I'm running 4 wyze cams into firgate without any issues.
If you are buying new cameras, it looks like Reolink is the way to go. Would highly recommend their POE cams.
If you dont want to flash your cameras (its super easy), you can look at wyze bridge to get the rtsp streams locally. I'm currently doing this for my wyze doorbell. Its not the most stable thing, but it works 80+% of the time. You can add it directly to supervisor.
