We have about the simplest/cheapest mechanical chimes you can get. (2 total, one on each floor).
Add “Older than dirt” and that’s what I have too. House was built in the late 70s.
Did your Reolink doorbell come with a little battery-looking-device that you had to wire into the mechanical chimes?
How long have you had yours in service? And what model is it, if I might ask.
Thanks. I’m looking into this. Never heard of this company before, but that sounds pretty compelling.
