Can someone provide a wiring diagram or directions to use two google nest doorbell wired (2nd gen) to a single mechanical doorbell chime? I will have one doorbell on the front door and one on the back doorbell. I am in the process of replacing the existing transformer with a 16V30VA transformer but was unsure how to wire 2 doorbells.
This Google Nest Help page below has 3 diagrams. The second, labelled "Two Nest doorbells, two chimes", is mislabeled, and is actually a diagram for two 2nd Gen Google Nest Doorbells with one chime.
