System and method for using a wireless device as a sensor for an energy management system

Abstract

The invention comprises systems and methods for detecting the use of networked consumer electronics devices as indications of occupancy of a structure for purposes of automatically adjusting the temperature setpoint on a thermostatic HVAC control. At least one thermostat is located inside a structure and is used to control an HVAC system in the structure. At least one networked electronic device is used to indicate the state of occupancy of the structure. The state of occupancy is used to alter the setpoint on the thermostatic HVAC control to reduce unneeded conditioning of unoccupied spaces.

What is claimed is: 
     
         1 . A method for varying temperature setpoints for an HVAC system comprising:
 determining whether one or more networked electronic devices inside a structure are in use;   determining whether said use of said networked electronic devices indicates occupancy of said structure; and   adjusting the temperature setpoint on a thermostatic controller for an HVAC system for said structure based upon whether or not said structure is deemed to be occupied.
