Do I need 2 pro kits for 2 internal mechanical chimes

My House has 2 internal mechanical chimes, the Ring doorbell pro comes with one pro kit which should be wired to the chime. Do I need 2 pro kits, one for each chime? or do I just use the one given on either chime?

Good question, @mkj49! The one Pro Power Kit will work just fine for this setup. There should be a main chime kit, or one closer to the door, in which this is the chime we recommend installing the Pro Power Kit on. Check out our help center article for a visual on this wiring diagram. I hope this helps! :slight_smile:
