wherein the controller is configured to receive the operational data from the one or more additional thermostats.

6. The system of claim 5 , wherein the controller is configured to receive an indication that one of the additional thermostats is a priority thermostat.

7. The system of claim 1 , further comprising:

one or more sensors to record at least a portion of the operational data, wherein the portion includes one or more of a current ambient temperature, a current ambient humidity and occupancy in the building, wherein the one or more sensors are configured to wirelessly transmit the respective portion of the operational data; and

wherein the controller is configured to receive the portion of the operational data from the one or more sensors.

8. The system of claim 1 , wherein:

the controller comprises a terminal block communicatively coupled to the thermostat using a wired connection; and

the controller is configured to receive 24 volts control signals from the thermostat over the wired connection.

9. The system of claim 1 , wherein:

the communication module of the controller comprises a wireless interface capable of wirelessly communicating with one or more computing devices; and

the controller is configured to wirelessly receive at least a portion of the operational data from the one or more computing devices.

10. The system of claim 9 , wherein the computing device includes at least one of a laptop, a notebook computer, a tablet computer, a smartphone, a smart watch, a netbook, or a desktop computer.

11. The system of claim 1 , wherein the one or more equipment comprises at least one of one or more furnaces, one or more air conditioners, one or more air handlers or one or more heat pumps.

12. A controller for controlling an indoor climate of a building, comprising:

a communication module configured to exchange operational data with a thermostat configured to wirelessly transmit the operational data;

an equipment interface configured to communicate control signals to one or more equipment of a heating ventilation and air-conditioning (HVAC) system to control operation of the one or more equipment; and

a processing unit communicatively coupled to the communication module and the equipment interface;

wherein the processing unit is configured to:

receive the operational data wirelessly transmitted from the thermostat using the communication module;

determine based on the operational data a control plan to operate the one or more equipment of the HVAC system; and

operate the one or more equipment of the HVAC system based on the control plan.

13. The controller of claim 12 , wherein the operational data comprises one or more of current ambient temperature in the building, current ambient humidity in the building, occupancy data, a temperature set point, a humidity set point and a target rate of temperature change.

14. The controller of claim 12 , wherein:

the communication module of the controller comprises one or more of:
