Ok, so it appears the only way to power the Pro 2 is:
- With an “indoor only rated” plug in adapter OR
2 Doorbell transformer with powerpack installed on a mechanical chime
You cannot wire the Pro 2 directly to a standard doorbell transformer, by passing a typical mechanical chime on the same electrical circuit? It appears you can with the Pro 1, you need to pull some tabs of the power pack etc. but those tabs don’t exist on V3 Power Pack.
That critical piece of information would have been good to know before I started this project.
The wiring on my old doorbell chime is too thin (22 gauge) for a video doorbell, so I ran a new line (18 gauge) on a shorter, new route direct to the front door to power the new Ring Pro 2.
My new chime is the digital Ring Chime Pro extender.
BTW I tried to get this issue cleared up by calling Ring directly, but got conflicting information.
