My old analog doorbell/intercom broke last year, I only got around to replacing it with a smart wifi doorbell last month (when the sticky note saying "doorbell broken please knock" blew off again). It turns out the chime signalling (EV1527 433MHz) is the same as my home alarm, and when I went to open the door to pair it with the newly mounted doorbell it paired with the front door sensor first. Now I get three chimes (motion, doorbell, door). I have not yet been able to unpair the chime, there is no reset, and it accumulates devices rather than overwrites. I'm not sure if the ability to answer the door while away is a good trade off given the complexity, and potential security issues.
