Lock does not seem to "know" that it is already unlocked or locked

Danalock is not aware of it’s state.

I would like this scenerio to happen : when I am home and the door is unlocked( either by me unlocking it or from a routine because I left and came back)…when my wife arrives home the lock already knows it is unlocked and won’t try to unlock again. ( Possibly saving on battery and the fact that it grinds which may or may not have an effect in the long run.)
