This piston unlocks the front door when the storm door opens, if my or my wife’s phone has entered the geo field in the last 10 minutes. This was my solution to the very wide geo field unlocking too soon.
It also turns the lights on if we’re coming back from away after sunset, or if the system is in home but all the first floor lights are off after sunset.
If we both leave the house for longer than 10 minutes, it ensures the front door is locked.
