1. A controller comprising:

  • one or more processors for controlling an environmental condition within an enclosure, wherein the controller is configured to operate in an away mode that causes an operative setpoint for the environmental condition to be reduced to a more energy-efficient level;

    one or more memories that store historical occupancy-event data; and

    instructions stored in the one or more memories that, when executed by the one or more processors, cause the one or more processors to;

    detect a time interval of a first duration in which no occupancy events are sensed;

    determine that the time interval in which no occupancy events are sensed is indicative of an away condition for the enclosure using an algorithm that uses the historical occupancy-event data corresponding to the time interval;

    cause the controller to automatically enter into the away mode based on determining that the time interval in which no occupancy events are sensed is indicative of the away condition;

    receive an input from a user while in the away mode indicative that the time interval in which no occupancy events were sensed did not indicate an away condition for the enclosure; and

    modify, based on receiving the input, the historical occupancy-event data such that, for a future time interval corresponding to the time interval, a probability that the algorithm will incorrectly determine whether a lack of occupancy events during the future time interval is indicative of an away condition for the enclosure is reduced.
