Garage door that closes itself after you forget

1// Garage door auto-close: closes the door when it has been open too long.2// Needs a reed switch on an Add-on input to know when the door is shut.3 4let CONFIG = {5  autoCloseMin: 10,6  reedInputId: 100,7  openState: false,8  travelSec: 30,9  pulseMs: 500,10  switchId: 0,11};12 13let closeTimer = null;14// Set when an auto-close didn't shut the door.
