I need two types of Bluetooth locking mechanisms. One that is Wifi capable and one that is not. They must:
1. Integrate with a Real Estate Application I am developing.
2. Both locks must affix to an existing door lock of a home and not require invasive installation
3. Both must automatically lock itself after a specific duration has surpassed when the lock was first unlocked.
3. The Wifi lock must be able to send an electronic message via Wifi through the internet to state whether or not it has locked.
