I added these large magnetic door sensors to our alarm system.
My thought is that I probably won't keep anyone out who wants in. I do want the alarm to go off.
Plus, it made it easy to tie into our automation for alerts if left open at night and we don't have to worry about locking the inside garage door. This has worked reliably for 15+ years.

Note: we also recently got a meross, for remote control via our iphones. I have not wired it in yet.
