Utilizing home thermostat as a wireless gateway for communicating with HVAC equipment

A heating, ventilation and air-conditioning (HVAC) system for a structure, comprising one or more of:

• an outdoor unit disposed at an exterior of the structure;
• an indoor unit disposed at an interior of the structure,
• the HVAC system further comprising a thermostat configured to control various operations of the outdoor and indoor units to maintain desired environmental conditions in the interior of the structure,
• wherein:
• each of the outdoor and indoor units comprises a wireless transceiver which is communicative with a cloud computing element,
• the thermostat is wirelessly communicative with the cloud computing element and with the wireless transceiver of each of the outdoor and indoor units,
• the outdoor unit further comprises a first processing element configured to control equipment operations in accordance with first control software and to generate and store first diagnostic information wherein the first control software is updateable and the first diagnostic information is accessible via direct wireless communications between the first processing element and the cloud computing element and via indirect wireless communications between the first processing element, the thermostat and the cloud computing element in response to automatic commands from the cloud computing element to update the control software and to access the diagnostic information, and
• the indoor unit further comprises a second processing element configured to control equipment operations in accordance with second control software and to generate and store second diagnostic information wherein the second control software is updateable and the second diagnostic information is accessible via direct wireless communications between the second processing element and the cloud computing element and via indirect wireless communications between the second processing element, the thermostat and cloud computing element in response to automatic commands from the cloud computing element to update the control software and to access the diagnostic information.

A method of operating a heating, ventilation and air-conditioning (HVAC) system for a structure, which comprises a thermostat, an outdoor unit and an indoor unit, the method comprising:

• providing the thermostat as a gateway between the cloud computing element and the outdoor and indoor units;
• establishing direct wireless communications between a cloud computing element and the outdoor unit;
• establishing direct wireless communications between the cloud computing element and the indoor unit;
• establishing indirect wireless communications between the thermostat, the cloud computing element and the outdoor unit;
• establishing indirect wireless communications between the thermostat, the cloud computing element and the indoor unit;
• updating control software and accessing diagnostic information of the outdoor unit via the direct and the indirect wireless communications in response to automatic commands from the cloud computing element to update the control software and to access the diagnostic information of the outdoor unit;
• and
• updating control software and accessing diagnostic information of the indoor unit via the direct and the indirect wireless communications in response to automatic commands from the cloud computing element to update the control software and to access the diagnostic information of the indoor unit.
