Don’t listen to him. Sure it may take a few hours a day over the course of a month or so to get right, but with the time you’ll save from all that automation you’ll break even in a few hundred years - and then it’s all gravy!
When you’re not home it becomes part of the alarm system. When you are home it can turn on the lights or heating (or extractor fan in the bathroom) and you can aggregate it with other sensors to measure occupancy to turn those things off again. If you use Home Assistant (or something like it) you can use it to go anything that can be inferred from a door being used.
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.
Resist the temptation, hundreds of hours will be lost down that rabbithole after you start.
Though, it is kinda cool stuff, when it’s working.

what’s a door sensor good for?
