Oh, okay. I think you’re boned.
I could totally be wrong about that. My understanding (based on discussion in another topic) is that Video Doorbell Pro and Chime Pro are pre-paired and that Video Doorbell Pro requires a functioning Chime Pro in order to have a wireless connection, so I wouldn’t expect you to be able to connect to your Video Doorbell Pro from the app if the Chime Pro is out of service. Is that what you’re experiencing?
I’d suggest trying a factory reset, but I imagine you’ve already done that.
Because of the pre-paired nature of the devices, I’m not sure if a new Chime Pro can be paired to an existing Video Doorbell Pro. I don’t know how they’d do the Bluetooth handshake (or whatever is required to pair). One thing that I’m really curious about now that I think about it is whether or not a Roku Enhanced Chime SE would pair to a Wyze Video Doorbell Pro. I have no idea if something like that would work (probably not), but my understanding is that the hardware is essentially the same if not identical. (Information available from the FCC indicates that the hardware tested was the same but with different model numbers depending upon whether Wyze or Roku was going to sell it, though I understand the firmware differences are significant and that Roku devices can’t be set up in the Wyze app and vice versa.)
Hopefully someone with Video Doorbell Pro experience has a better answer for you.
