An apparatus for adjusting scheduled events in an automation system of a building at a predetermined location includes a location module, an arrival time module, and a regulator module. The location module determines a current location of a user in response to a triggering event. The arrival time module calculates an estimated time of arrival of the user at a residence. The regulator module adjusts a characteristic of a scheduled event in the automation system in response to comparing the estimated time of arrival of the user to a time of the scheduled event in the automation system.
