Abstract: The present technology is directed to a system and method for regulating and optimizing energy consumption within a home based on intelligent control of electrical appliances and home-run circuits. The present technology taps into home-run circuits at the circuit breaker box in order to extract select set of parameters from current and voltage waveform required to identify the type and ON/OFF state of appliances or devices connected to each of the home run circuits. Therefore generating an active device list from which it construct contextual scene that reflect the level of occupancy and the condition of energy consumption in the house (i.e., where individuals are and what they are doing). Based on this information the present technology controls the actuation of home-run circuits, as well as the operation of HVAC system and a series of smart devices/systems in such a way so as to optimize the overall home/office energy consumption.
