Wyze cameras already have sound detection of smoke alarms. How about adding detection of doorbell chimes, and then all I’d need to do is use my existing doorbell, position the camera and chime so the camera can hear when someone presses the doorbell, and problem solved! I understand there are many different types of doorbell chime so it won’t work with all of them, but if you just choose a common, cheap one with a distinct ring and support that one, then that would do.
Or, another option for anyone who can’t wait for Wyze to implement this is to pull apart an old smoke alarm, and wire that up to trigger from your doorbell, so Wyze will detect it as a smoke alarm and warn you. Bonus points if your method to trigger the smoke alarm is through a Rube-Goldberg style device that ends with some burnin tinder. Or, a little device that plays a short recording when pressed, on which you’ve recorded the sound of a smoke alarm.
