I always send my guests a follow-up message an hour after they have arrived at the property. I know the time they arrived at the property based on the notification I get from the Schlage app that the access code for that guest was used to unlock the door. It would be great if Schlage could report the logs back to OwnerRez so that we could then trigger messages based on the timing of lock/unlock events. Using the check-in time wouldn't really work for me as guests rarely arrive exactly at the check-in time and I don't want to message them too early or too late.
