Abstract: A system and method that simulates actual use of appliances and devices in a building learns actual usage patterns over an extended length of time. By replaying such learned sequences to controlled devices whereby the devices are turned on at off, the on/off sequences appear more natural making a building or dwelling appear to be occupied. The realistic control of devices mimics occupancy of a dwelling. In a learn mode, an intelligent control system records and stores the on/off events of controlled devices in the dwelling. In a run mode, the intelligent control system replays the on/off events thus reflecting the usage patterns of the resident.
