The Wyze doorbell has the same issue as the Wyze cams. When I lose power, sometimes it does not connect back to wifi and needs a hard power off reset. Now you can run to your fuse panel and find the breaker if there is one and power that and everything else off also, but who wants to run to their fuse panel
The original doorbell is in a living space and I wired a switch there, so each time this doorbell loses wifi or I get a power out , I can just go to the original doorbell wiring and flick a switch to reset the Wyze doorbell
You can see the entire installation here and how.
