Aurmur provides an integration with your SmartThings hub to automatically manage guest lock codes for Airbnb, VRBO, and HomeAway.
Reservation information is pulled from the different platforms. Guests are automatically sent an app message, welcome email, and text message with a lock code before their stay. At check-in time the code is automatically activated on the lock. At checkout time, the code is automatically deactivated.
