I suspect that Google has been tinkering again and maybe broke something. In the past, I’ve done something similar to what you’re describing with a Google Home Hub (1st Gen) and Wyze Video Doorbell v2, but I’ve had my Video Doorbell v2 disconnected for a while, as I’d like to redesign my 3D-printed mount for it. Looking through my own posts, I can see that automations using Google Home Household Routines to stream a Wyze Cam to a Home Hub were failing for me back in April, and I still attribute that to Google.
If you can share some details about the timing of your issue and the kinds of Wyze Automations and/or Google Home Routines you’re using, then that might shed some light, but my first thought is still that this is because of something Google has done.
