There are some locks and door lock manager software that is integrated with Airbnb, so if dates are changed or canceled, it will update on the lock, but for changing individual check in access time, would still need to do that on the lock or door lock manager software app.
I just send a message if it can be ready a little sooner, and change it on the door lock app, which in my case is a door lock manager that's integrated with ABB.
