My wired Nest Hello Gen 1 doorbell recently lost power randomly. Resetting at the breaker box would power the cam back up, but it would go down again after an hour or so. After doing some research I decided to upgrade the original transformer to a 24V 40VA. The camera is still losing power randomly, though after resetting at the breaker it sometimes maintains power for 48 hours, 8 hours, 3 hours etc - point is it stays on longer than with the old transformer but is still not reliable. I’ve measured the output at the transformer (27V) and at the doorbell (26V), double checked all wiring. When the camera loses power, sometimes I receive an “extreme temperature” warning, sometimes just an “offline” warning. And once it powered back up on its own in the middle of the day while I was at work, but then lost power again almost immediately.
I’ve read about the internal battery failing over time, and the doorbell is pretty old as far as tech goes - anything else I should check before trying a brand new doorbell?
