Setup automation hallway

ref #110

• Ensure transition time is at least twice active time human sensor
• Ensure door occupancy is max 3 seconds by reducing motion sensor timeout
• The state transition calculation needs to be separate from trigger specific logic
• Means all motion sensors need to be installed on the opposite side of the door how the door opens to better ensure motion is always triggered

Thoughts:

1. If transition time is shorter than human timeout state remains present
2. If door occupancy change is missed then room is left in wrong state. This can happen with an open door and motion not being triggered.
3. If state changes to absent and door occupancy is still happening then a new change to entering is missed.
4. If the door occupancy change lasts long then transition is possible
   • present -> leaving -> absent -> entering -> absent
   • absent -> entering -> present
5. To prevent flipping between states a "leave" transition needs to hold for a particular time?
6. What to do when door occupancy is still going when switching states?
