Proximity detection module on thermostat

1. A system, comprising:

a thermostat disposed at a site and including a communication module capable of communicating with a mobile device associated with the site;

said thermostat including a proximity detection module disposed thereon, said proximity detection module having a home mode and an away mode;

said thermostat configured to enable the away mode;

said proximity detection module configured to:

detect a presence of a user at the site; and

alter an operating condition of the thermostat during the away mode in response to the detected presence of the user.

2. The system of claim 1 , wherein the thermostat includes a generally round housing.

3. The system of claim 2 , wherein the housing includes a control mechanism configured to rotate clockwise and counterclockwise to allow for the selection of the home mode and the away mode.

4. The system of claim 1 , wherein the thermostat includes an LCD display configured to indicate use of the home mode, the away mode and display a current set-point.

5. The system of claim 4 , wherein the LCD display has an energy savings indicator to provide a visual indication of energy savings related to the away mode.

6. The system of claim 4 , wherein the LCD display has an energy history section to display how much energy has been used daily by an HVAC system at the site.

7. The system of claim 4 , wherein the LCD display has a schedule section to display scheduling data of the thermostat.

8. The system of claim 1 , wherein the thermostat is further configured to:

detect a selection of a home setting or an away setting on a user interface of the mobile device;

enable the home mode of the proximity detection module in response to the home setting; and

enable the away mode of the proximity detection module in response to the away setting.

9. The system of claim 1 , further comprising:

a second thermostat disposed at a site and including a communication module capable of communicating with the mobile device, said thermostat configured to:

alter an operating condition of the second thermostat in response to detecting the change in the location e of the mobile device.

10. The method of claim 1 , wherein the thermostat is further configured to:

communicate with a network location that stores distance information of a plurality of mobile devices including a first mobile device and a second mobile device;

detect a first distance information of the first mobile device relative to the site;

detect a second distance information of the second mobile device relative to the site;

communicate the first distance information of the first mobile device and the second distance information of the second mobile device to the network location to be compared; and

initiate the change to the operating condition of the thermostat if a change in the first distance of the first mobile device is different than a change in the second distance of the second mobile device.

11. The system of claim 1 , wherein the thermostat is further configured to:

initiate a reporting interval from the mobile device to a network location in response to the distance; and

initiate communication of a control of the operating mode using the reporting interval and the location.

12. The system of claim 1 , wherein the thermostat is further configured to:

detect an availability of a WIFI network including a device connected to the WIFI network;

access the device using the WIFI network to detect an operating condition of the device; and

initiate an altering of the operating condition of the network device using the WIFI network.
