How Many Pro Power Kits Do I need?

I have a house with 2 mechanical doorbell chimes. Do I need a pro power kit for each chime or do I need just one? I want both doorbell chimes to work so we can hear it in basement.

Hi @Cymbo. That’s a great question! With one Video Doorbell Pro and two internal doorbells, you’ll only need one Pro Power Kit. You can take a look at the wiring diagram for how that would look in our Help Center Article here. I hope that helps! :slight_smile:
