I’ve been trying your suggestion since my last post. At first it seemed to do the trick. But since last week, random notifications seem to pop up more often.
Then there is another problem: The doorbell seems like it is in a very deep sleep sometimes. Visitors press the bell but nothing happens. A lot of times. It usually starts to “wake” after a second or even third press. Also a very mild short press does not seem to wake the doorbell. Holding the button for over a second seems to do the trick. But I want my doorbell to respond when someone presses it. Not after you find some kind of magic threshold.
I start to believe that my doorbell is having a defect of some sort.
