I have Android Presence unlock my door (Schlage Century touchscreen) when I arrive, and that appears to be working. The problem is, it unlocks the door when I drive up, and by the time I park and walk up to the door, the timeout has already occurred, and the door has re-locked itself. I don’t want to turn the auto relock feature off. So, what I would like is to build in a delay, say 2 minutes from the time it presently says due to the presence of my android, it is unlocking the door. Is there any way to do this?
You could then have ST lock the lock after a longer period of time or after you open & close the door. ST gives you a lot more flexibility than the hard-coded lock-after-4-minutes in the lock itself, without sacrificing the security you want.
Also, consider hooking the “unlock” to a Presence Sensor inside your car, instead of to your phone. Your car won’t be recognized until you are much closer to your destination (within Zigbee transmit range).
