Are there ready-made sensors for tracking the opening and closing of a door lock (namely, a lock, not a door)?

Question

Smart House

It is necessary to receive information at what time the lock was opened (mechanical lock) and when it was closed (maybe there are not sensors, but special locks).

Answer 1

the simplest is a reed switch in the door jamb, and a magnet in the lock

Answer 2

The easiest way is to make a sensor in the door frame (IR proximity, induction, Hall sensor) and determine the position of the main deadbolt, additional deadbolts.

Answer 3

You need an electromechanical lock, perhaps something like this:

And a controller for it, for example:
