@s.rodighiero I currently do this with a property but I do it with SmartThings using the RBoy Rental Control app.
I’m working on building out an integration for HA, as I’m trying to get completely off of SmartThings, that will leverage the KeyMaster integration for the lock control. The real missing piece of this puzzle is the calendar control with default check-in / check-out times that are also overridable.
I haven’t had a lot of time to work on it yet, but have already validated the calendar acquisition and modification (AirBnB doesn’t put in/out times in their entries so they have to be modified upon ingest). That was just some side scripting though. I need to make it a full fledged integration!
