Abstract

A temperature control apparatus for controlling operation of at least one temperature-modifying device includes a housing, a wireless communication module configured to communicate with a remote Internet-based server, and a controller in communication with the wireless communication module. The controller is configured to: (i) control operation of the temperature modifying device in response to a comparison of a measured ambient temperature with a setpoint temperature, (ii) in a user-selectable first mode of operation, during a first time period during a day, poll the remote server at a first rate of at least six times per hour, using the wireless communication module, for an instruction to change the setpoint temperature, and (iii) in the first mode of operation, during a second time period, poll the remote server at a second rate that is lower than the first rate, using the wireless communication module, for an instruction to change the setpoint temperature.

Claims

1. A temperature control apparatus for controlling operation of at least one temperature-modifying device, the apparatus comprising:

(a) a housing;

(b) a wireless communication module contained within the housing and configured to communicate with a remote Internet-based server; and

(c) a controller contained within the housing and in communication with the wireless communication module, the controller being configured to;

(i) control operation of the at least one temperature modifying device in response to a comparison of a measured ambient temperature with a setpoint temperature,

(ii) in a user-selectable first mode of operation, during a first pre-scheduled time period during a day, poll the remote server at a first rate of at least six times per hour, using the wireless communication module, for an instruction to change the setpoint temperature,

(iii) in the first mode of operation, during a second pre-scheduled time period during the day different from the first time period, poll the remote server at a second rate that is lower than the first rate, using the wireless communication module, for an instruction to change the setpoint temperature,

(iv) in a second user-selectable mode of operation, during the first pre-scheduled time period of the day, poll the remote server at a third rate that is between the first rate and the second rate, using the wireless communication module, for an instruction to change the setpoint temperature, and

(v) in the second mode of operation, during the second pre-scheduled time period of the day, poll the remote server at a fourth rate that is lower than the second rate, using the wireless communication module, for an instruction to change the setpoint temperature.

2. The temperature control apparatus of claim 1, wherein the controller is further configured to, in the first mode of operation, during a third pre-scheduled time period during the day different from the first and second time periods, poll the remote server at a fifth rate that is between the first and second rates, using the wireless communication module, for an instruction to change the setpoint temperature.

3. The temperature control apparatus of claim 2, wherein the first pre-scheduled time period is from about 6 AM to about 9 AM and from about 5 PM to about 12 AM, the second pre-scheduled time period is from about 12 AM to about 6 AM, and the third pre-scheduled time period is from about 9 AM to about 5 PM.

4. The temperature control apparatus of claim 1, wherein the controller is further configured to:

(vi) in a third user-selectable mode of operation, during the entire day, poll the remote server at a rate that is higher than the first rate, using the wireless communication module, for an instruction to change the setpoint temperature.

5. The temperature control apparatus of claim 4, wherein the third mode of operation is only selectable if the temperature control apparatus is connected to a mains power supply.

7. The temperature control apparatus of claim 1, wherein the instruction to change the setpoint temperature includes a designation of a new setpoint temperature.

8. The temperature control apparatus of claim 1, wherein the instruction to change the setpoint temperature includes an indication for the controller to use a predetermined setpoint temperature corresponding to geolocation of the user outside of a predefined area surrounding the temperature control apparatus.

9. The temperature control apparatus of claim 1, wherein the first pre-scheduled time period is from about 6 AM to about 12 AM and the second pre-scheduled time period is from about 12 AM to about 6 AM.

10. The temperature control apparatus of claim 1, further comprising:

(d) a battery configured to provide power to at least the controller and the wireless communication module.

11. The temperature control apparatus of claim 1, further comprising:

(d) a user interface located on the housing and configured to receive at least input from a user to change the setpoint temperature.

12. The temperature control apparatus of claim 1, wherein the controller is further configured to:

(vi) turn off the wireless communication module in between polls to the remote server.

6. A temperature control apparatus for controlling operation of at least one temperature-modifying device, the apparatus comprising:

(a) a housing;

(b) a wireless communication module contained within the housing and configured to communicate with a remote Internet-based server; and

(c) a controller contained within the housing and in communication with the wireless communication module, the controller being configured to;

(i) control operation of the at least one temperature modifying device in response to a comparison of a measured ambient temperature with a setpoint temperature,

(ii) in a user-selectable first mode of operation, during a first pre-scheduled time period during a day, poll the remote server at a first rate of at least six times per hour, using the wireless communication module, for an instruction to change the setpoint temperature,

(iii) in the first mode of operation, during a second pre-scheduled time period during the day different from the first time period, poll the remote server at a second rate that is lower than the first rate, using the wireless communication module, for an instruction to change the setpoint temperature,

wherein the controller is further configured to evaluate a response time for the wireless communication module to send and/or receive messages, and wherein the controller is further configured to adjust at least one of the first or second rates based on the evaluated response time.

13. A method for remotely modifying a setpoint temperature in a temperature control apparatus that controls operation of at least one temperature-modifying device, the method comprising:

(a) providing a mobile application configured to be stored and executed on a mobile device by a user of the temperature control apparatus;

(b) receiving, at an Internet-based remote server, an instruction from the mobile application to change the setpoint temperature in the temperature control apparatus;

(c) polling, in a user-selectable first mode of operation by a controller of the temperature control apparatus using a wireless communication module of the temperature control apparatus, the remote server for the instruction to change the setpoint temperature, the polling occurring at a first rate of six times per hour or more during a first pre-scheduled time period during a day and at a second rate that is lower than the first rate during a second pre-scheduled time period of the day;

(d) polling, in a user-selectable second mode of operation by the controller of the temperature control apparatus using the wireless communication module of the temperature control apparatus, the remote server for the instruction to change the setpoint temperature, the polling occurring at a third rate that is between the first rate and the second rate during the first pre-scheduled time period during the day and at a fourth rate that is lower than the second rate during the second pre-scheduled time period of the day; and

(e) controlling, by the controller of the temperature control apparatus, operation of the at least one temperature modifying device in response to a comparison of a measured ambient temperature with the changed setpoint temperature.

14. The method of claim 13, wherein, in the first mode of operation, the polling occurs at a fifth rate that is between the first and second rates during a third pre-scheduled time period during the day different from the first and second pre-scheduled time periods.

15. The method of claim 14, wherein the first pre-scheduled time period is from about 6 AM to about 9 AM and from about 5 PM to about 12 AM, the second pre-scheduled time period is from about 12 AM to about 6 AM, and third pre-scheduled time period is from about 9 AM to about 5 PM.
