1. A method for detecting occupancy of an enclosure comprising:

  • determining a probability that occupants of the enclosure will depart from or arrive at the enclosure at a certain time of the day based on a pre-existing model of occupancy patterns, the pre-existing model being available to a thermostat at the time of installation of the thermostat in the enclosure, the model being indicative of a probability that occupants of the enclosure will depart from and arrive at the enclosure at certain times over the course of a day;

    monitoring, by the thermostat after installation of the thermostat in the enclosure, communication signals which indicate a likelihood of occupancy of the enclosure ranging from not occupied to occupied;

    revising the model of occupancy patterns based at least in part on the monitored communication signals; and

    determining a probability that occupants of the enclosure will depart from or arrive at the enclosure at a certain time of the day based on the revised model of occupancy patterns,wherein the pre-existing model is generated based on a type of information other than the monitored communication signals.
