Hi, I would suggest that you investigate The Airlocking System. I think it would satisfy all your requirements.
Here is a cut and paste from their website:
THE AIRLOCKING SYSTEM:
INSTALL LOCK AND HUB:
AirLocking ships you a Smart lock system. You just need to connect the system to the internet and follow the straightforward instructions to install the lock.
GUESTS RECEIVE DOOR CODE:
AirLocking automatically emails your guests' door codes in advance of their trips along with other check-in information you wish to pass along. You are copied on these emails for your tracking.
LINK WITH AIRBNB CALENDAR:
AirLocking seamlessly links with your Airbnb calendar to track reservations. The AirLocking portal provides status information and allows you to control guest notifications.
LOCK UPDATED WITH CODES:
AirLocking enables the door code in the lock at check-in time and disables it after checkout time. AirLocking also allows you to have codes for your own use which are separate from the guest codes.
CHECK-OUT BUTTON: (Patent Pending)
Airlocking has added a new feature--a CHECK-OUT BUTTON. When guests leave, they are asked to push this button. Instantly, the Host is alerted to their departure and can proceed with Cleaning Services or Repairs.
