The ePropertyCare Connected Lock system allows a user to setup codes with a finite start date/time and end date/time. This is targeting AirBnB hosts that want a code to start at check-in time, and end at check-out time. There are two ways to do this:
1) From your phone: This video shows how to set limited-use AirBnB guest codes in the app: https://youtu.be/aqX123LnPLo
2) From computer: This video shows how to setup limited-use codes from your computer: https://youtu.be/tt1MLyJ7xiw
The building36 website allows you to create temporary codes from the Users section. Follow the instructions in the video to see how to do this.
