How to model state of leaving/entering home

I have two sensors: One detecting if the door is open or closed, another if movement has been detected in the corridor. I want to detect if the person has left or entered home. Usually the person has left if:

1. movement detected


2. door opened


3. door closed


4. no movement detected

Because of the timing problems and the overlapping states (door is open but person also moves) I think the design pattern state is not appropriate here. But I'm struggling to find a better structure.

Any help?
