    detecting events that indicate occupancy;

    storing a record of the events that indicate occupancy in the one or more memory devices;

    causing the controller to enter an auto-away state where the controller temporarily enters a more energy-efficient mode, wherein a determination that the controller should enter the auto-away state is based at least in part on;

    a length of a current time interval during which no events that indicate occupancy were detected; and

    the stored record of the events that indicated occupancy during previous time intervals;
