trigger

The most common automation there is. presence detected fires on the false to true transition of occupancy in the hallway, so somebody standing still does not re-run it. Its device id feeds get device state, which reads the illuminance the same sensor reports; < compares that against 30 lux and branch only lets light on run when the room is actually dark.
