Abstract

A wireless thermostat may be associated with a user account of an external web service that may facilitate remote access and/or control of the wireless thermostat. A remote device may be used to access a user's account hosted by the external web service. The wireless thermostat may be identified to the external web service and associated with the user's account by one or more unique identifiers previously delivered to the remote device from the wireless thermostat.

First claim

What is claimed is:

1. A method of associating a wireless thermostat with a user account of an external web service, the method comprising:
forming a first wireless network between the wireless thermostat and a device separate from the wireless thermostat, the device having a user interface;
using the user interface of the device to receive one or more access parameters from a user for accessing a second wireless network, the second wireless network capable of communicating with a wide area network for accessing the external web service;
once the one or more access parameters are received by the user interface of the device, transmitting the one or more access parameters from the device to the wireless thermostat via the first wireless network;
transmitting one or more registration parameters from the wireless thermostat to the device via the first wireless network, the one or more registration parameters uniquely identifying the wireless thermostat;
connecting the wireless thermostat to the second wireless network using, at least in part, the one or more access parameters, thereby making the wireless thermostat available on the second wireless network and the wide area network; and
using the device to access the external web service and to then associate the one or more registration parameters received from the wireless thermostat with the user account of the external web service.

2. The method of claim 1 , wherein the device is a wireless device.

3. The method of claim 2 , wherein the wireless device is a lap top computer, a tablet computing device, or a smart phone.

4. The method of claim 1 , wherein the one or more registration parameters are loaded into the wireless thermostat at the factory.

5. The method of claim 1 , wherein the first wireless network and the second wireless network are both WiFi wireless networks.

6. The method of claim 1 , wherein the first wireless network is a blue tooth wireless network, and the second wireless network is a WiFi wireless network.

7. The method of claim 1 , wherein the first wireless network is a Zigbee wireless network, and the second wireless network is a WiFi wireless network.

8. The method of claim 1 , wherein the second wireless network includes an access point that provides communication between the second wireless network and the wide area network.

9. The method of claim 1 , wherein the one or more access parameters include a SSID of the second wireless network.

10. The method of claim 1 , wherein the one or more access parameters include a passcode for the second wireless network.

11. The method of claim 1 , wherein the one or more registration parameters include a MAC ADDRESS and/or CRC code of the wireless thermostat.

12. The method of claim 1 , wherein the one or more registration parameters are encoded in a hyperlink that, when selected, links to the external web service.

13. The method of claim 1 , wherein the hyperlink is transmitted from the wireless thermostat to the device, and is available for selection on the user interface of the device.

14. The method of claim 1 , wherein the one or more registration parameters are received from the wireless thermostat by an application running on the device, and wherein the application provides the one or more received registration parameters to the external web service when accessing the external web service.

15. The method of claim 1 , wherein the wireless thermostat disconnects from the first wireless network before connecting the wireless thermostat to the second wireless network.

16. The method of claim 15 , further comprising performing a reset on the wireless thermostat before connecting the wireless thermostat to the second wireless network.

17. The method of claim 1 , wherein the wireless thermostat provides a web-page to the device across the first wireless network, wherein the web-page accepts the one or more access parameters from the user via the user interface of the device.

18. The method of claim 1 , wherein the device executes an application program, and wherein the application program accepts the one or more access parameters from the user via the user interface of the device.

19. A method comprising:
hosting a wireless network at a wireless thermostat;
accepting a connection to the wireless network hosted by the wireless thermostat from a remote wireless device;
the thermostat receiving one or more access parameters associated with a local area network from the wireless device;
transmitting one or more registration parameters from the wireless thermostat to the remote wireless device for delivery to an external web service, wherein the one or more registration parameters uniquely identify the wireless thermostat;
the wireless thermostat connecting to the local area network as a client device using the one or more access parameters; and
the wireless thermostat communicating with an external web service, wherein the wireless thermostat is identified to the external web service by the one or more registration parameters.

20. A wireless thermostat configured to communicate with and control one or more HVAC components, the wireless thermostat comprising:
a temperature sensor;
a memory;
a controller, the controller configured to
accept a wireless connection with a remote wireless device;
receive one or more access parameters associated with a local area network from the remote wireless device via the wireless connection;
transmit one or more registration parameters to the remote wireless device for delivery to an external web service, wherein the one or more registration parameters uniquely identify the wireless thermostat;
connect to the local area network as a client device using the one or more access parameters received from the remote wireless device; and
communicate with an external web service at least in part through the local area network, wherein the wireless thermostat is identified to the external web service by the one or more registration parameters previously delivered to the remote wireless device.

21. A computer readable medium having stored thereon in a non-transitory state a program code for use by a wireless device connectable to a local area network, the program code causing the wireless device to execute a method comprising:
scanning for wireless networks using the wireless device, wherein at least one wireless network is hosted by a wireless thermostat;
connecting the wireless device to the wireless network hosted by the wireless thermostat;
receiving from the wireless thermostat one or more unique identifiers that uniquely identify the wireless thermostat via the wireless network hosted by the wireless thermostat;
storing the one or more unique identifiers in a memory of the wireless device;
transmitting one or more access parameters associated with the local area network that are stored in the memory of the wireless device to the wireless thermostat via the wireless network hosted by the wireless thermostat;
connecting the wireless device to an external web service hosted by an external web server; and
transmitting the one or more unique identifiers stored in the memory of the wireless device to the external web service.

22. The computer readable medium of claim 21 , wherein the external web service associates the one or more unique identifiers of the wireless thermostat with a user account on the external web service.

23. The computer readable medium of claim 21 , further comprising transm
