1. A controller for controlling energy consumption in a home, the controller comprising:
- a constraints engine to define sets of constraints for multiple appliances in the home corresponding to various home modes, convenience of service, and persona of an occupant of the home;
a modeling engine to model multiple paths of energy utilization of the multiple appliances to place the home into a desired state from a current context;
an optimal scheduler to receive the multiple paths of energy utilization, to generate a schedule as a function of the multiple paths and a selected persona with corresponding sets of constraints to place the home in a desired state, and to suggest a plurality of load schedules and set points for optimal energy conservation; and
an occupancy module to determine whether or not the home is currently occupied;
wherein the occupancy module infers occupancy from an overall energy utilization signature and indoor air quality sensor data, wherein the optimal scheduler automatically resets at least one thermostat mode of the home and automatically adjusts at least one thermostat setting of the home, in response to the occupancy module determining that the home is not occupied; and
wherein the controller correlates and maps fuzzy data to parameters that are used for scheduling and controlling operation of home loads.

Abstract
A controller for controlling energy consumption in a home includes a constraints engine to define variables for multiple appliances in the home corresponding to various home modes and persona of an occupant of the home. A modeling engine models multiple paths of energy utilization of the multiple appliances to place the home into a desired state from a current context. An optimal scheduler receives the multiple paths of energy utilization and generates a schedule as a function of the multiple paths and a selected persona to place the home in a desired state.

14. A method for controlling energy consumption in a home, the method comprising:
-
modeling multiple paths of energy utilization of multiple appliances via a specifically programmed computer to place a home in a desired state from a current context, wherein the appliances have variables selected as a function of home modes and home occupant persona; receiving the multiple paths of energy utilization via the computer; generating a schedule via the computer for control of the appliances as a function of the multiple paths and a selected persona to place the home in a desired state, wherein the schedule suggests a plurality of load schedules and set points for optimal energy conservation; inferring occupancy from an overall energy utilization signature and indoor air quality sensor data; and correlating and mapping fuzzy data to parameters that are used for scheduling and controlling operation of home loads; wherein at least one thermostat mode of the home is automatically reset and at least one thermostat setting of the home is automatically adjusted, in response to the home being determined not occupied. - View Dependent Claims (15, 16, 17, 18, 19)
