@scooterdog

now I’m having the problem of it interfering with my garage door opener

Is it a Chamberlain model? You might want to look around this topic:

Wyze Video Doorbell interferes with Chamberlain garage door opener

After I installed video doorbell, my garage door opener RF signal is blocked. I depowered the wyze video doorbell and the Chamberlain garage door openers work perfectly. What can I do, to not have the RF interference from the Wyze Video Doorbell?
