1. A method for varying temperature setpoints for an HVAC system comprising:
- storing at least a first HVAC temperature setpoint and at least a second HVAC temperature setpoint;
monitoring an activity status of at least one wireless device associated with one or more occupants of said structure, wherein said wireless device comprises a graphic user interface that can be used to view video content, wherein use of said wireless device comprises at least one of cursor movement, keystrokes or other user interface actions intended to alter a state of said wireless device;
determining a probability that the specific activity status of said wireless device is associated with the use of said wireless device by a specific occupant or occupants of said structure, where said probability is determined in part by the video content of the program or channel being viewed by said occupant on or with said wireless device and where said video content is not explicitly related to temperature setpoints;
determining whether a current HVAC temperature setpoint associated with said HVAC system is set to said first HVAC temperature setpoint or said second temperature setpoint;
prompting said one or more users, wherein said prompting sends a message to said wireless device recommending a change to said current HVAC temperature setpoint for said HVAC system;
in response to said prompting, receiving input from said one or more users; and
keeping said current HVAC temperature setpoint based upon said input from said one or more users.

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.

10. A system for altering the setpoint on a thermostat for space conditioning of a structure comprising:
-
at least one thermostat having at least a first temperature setpoint and at least a second temperature setpoint; at least one wireless device associated with one or more occupants of said structure, wherein said wireless device comprises a graphic user interface that can be used to view video content, wherein use of said wireless device comprises at least one of cursor movement, keystrokes or other user interface actions intended to alter a state of said wireless device; an application comprising one or more computer processors that receives data regarding an activity status of said wireless device and whether said thermostat is set to said first temperature setpoint, said application determining a probability that the specific activity status of said wireless device is associated with the use of said wireless device by a specific occupant or occupants of said structure, where said probability is determined in part by the video content of the program or channel being viewed by said occupant on or with said wireless device and where said video content is not explicitly related to temperature setpoints; said application prompting said one or more users wherein said application provides electronic notice to one or more of said users of said wireless device that said thermostat is set to one of said first temperature setpoint or said second temperature setpoint; and wherein said application in response to said prompting, receives input from said one or more users; and wherein said current temperature setpoint is set based upon said input from said one or more users. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
