Peace of mind. We have a light that lights up red when a door is open. At the end of the night we get an announcement “all doors closed” - last night I got an announcement telling me one door was open - I went there and sure enough: the magnet side of the sensor had fallen off, door was closed.
Depends on your level of trust. I trust the sensor to tell me the door is open/closed (which is a concern to know if people are actually coming in or out - can’t do that with the door closed)… I don’t trust a smart lock to always lock or unlock when I want it to, and those are the things that will give you a locked/unlocked status report. If anybody really wants to get in/out of our house it doesn’t matter if the doors are locked or not, they can always break a window.
what’s a door sensor good for?

so you use it for security? wouldn’t it make more sense to detect if the locks are locked?
