I’ve just purchased and installed a Ring Doorbell 3 Plus to replace an existing wired doorbell in the UK.
The existing dumb doorbell is connected to a mechanical chime that is outputting 10vac (which I checked with a multi-meter).
I fully charged the doorbell before intalling it. Once installed, it won’t trigger the mechanical chime when pressed, and it won’t draw power from the wires.
I took it out and put the old dumb doorbell in again to check that still works and it does, and the wires still give 10vac on the multi-meter.
I put the ring back and it still won’t use power or make the chime ring.
Am I missing something?
