I've been pulling my hair out trying to find my current doorbell transformer in order to upgrade it for a nest doorbell. I believe to have found it attached to my electrical panel after taking the cover off, but seemingly inside of the wall.
I believe this is the doorbell transformer but I'm not 100%. I see that it is wired to the same circuit breaker which does power the existing doorbell, and it looks like a transformer but I cannot get the greatest view. Is this definitely the doorbell transformer and is there an easier way to access it without cutting the wall?
