The idea is that I want an device that will allow me to take a Bowley lock, or any standard deadbolt and add access control to it. The external deadbolt lock should still work, but the device should detect that it has been opened and automatically re lock the door after a certain amount of time. This is more to make sure that a house door is locked in case you forget and to enable access to guests that show up for any reason. NOTE I'm not looking for a system that will connect to a mobile device, I'm looking for a system that will work with a commercial access control system, hardwired and connected to something like Ubiquiti Networks's upcoming access control devices. I'm not compromising security for the convenience. I am finding electronic deadbolts that go inside the door, but don't fit a standard deadbolt profile, why i need something external, to retrofit a door rather then replace it. Are there any such devices?
