Smart thermostat robust against adverse effects from internal heat-generating components

A method of determining an ambient temperature in an enclosure while compensating for internal heating effects of a thermostat, the method comprising:

• operating a plurality of heat-generating components within the thermostat;
• generating readings from a plurality of first temperature sensors, each of the plurality of first temperature sensors being disposed next to a corresponding one of the plurality of heat-generating components;
• generating readings from a second temperature sensor that is disposed away from the plurality of heat-generating components;
• storing a coefficient matrix in a memory device;
• combining a plurality of inputs to calculate an ambient temperature for an enclosure in which the thermostat is installed, the plurality of inputs comprising:
• readings from the plurality of first temperature sensors;
• readings from the second temperature sensor;
• and
• the coefficient matrix;
• and
• controlling an environmental system using the calculated ambient temperature.

A non-transitory, computer-readable medium comprising instructions that, when executed by one-or more processors on a thermostat, cause the one or more processors to perform operations comprising:

• operating a plurality of heat-generating components within the thermostat;
• receiving readings from a plurality of first temperature sensors, each of the plurality of first temperature sensors being disposed next to a corresponding one of the plurality of heat-generating components;
• receiving readings from a second temperature sensor that is disposed away from the plurality of heat-generating components;
• storing a coefficient matrix in a memory device;
• combining a plurality of inputs to calculate an ambient temperature for an enclosure in which the thermostat is installed, the plurality of inputs comprising:
• readings from the plurality of first temperature sensors;
• readings from the second temperature sensor;
• and
• the coefficient matrix;
• controlling an environmental system using the calculated ambient temperature.
