FACILITATING AMBIENT TEMPERATURE MEASUREMENT ACCURACY IN AN HVAC CONTROLLER HAVING INTERNAL HEAT-GENERATING COMPONENTS
First Claim
1. A smart-home device for monitoring or controlling a condition or system on the home comprising, the smart-home device comprising:
- a housing;
a plurality of temperature sensors, each being positioned at different locations, and each being configured to provide temperature sensor measurements; and
a processing system disposed within the housing, the processing system being configured to be in operative communication with the one or more temperature sensors to receive the temperature sensor measurements, wherein said processing system is configured to;
(i) operate in a plurality of operating states including a first operating state characterized by relatively low power consumption and a corresponding relatively low associated heat generation and a second operating state characterized by relatively high power consumption and a corresponding relatively high associated heat generation;
(ii) during time intervals in which the processing system is operating in the first operating state, process the temperature sensor measurements according to a first ambient temperature determination algorithm that uses a first combination of the plurality of temperature sensors; and
(iii) during time intervals in which the processing system is operating in the second operating state, process the temperature sensor measurements according to a second ambient temperature determination algorithm that uses a second combination of the plurality of temperature sensors that is different from the first combination of the plurality of temperature sensors.

Abstract
A smart-home device may include a plurality of temperature sensors, and a processing system that may be configured to operate a first operating state characterized by relatively low power consumption and a corresponding relatively low associated heat generation, and a second operating state characterized by relatively high power consumption and a corresponding relatively high associated heat generation. During time intervals in which the processing system is operating in the first operating state, the processing system may process the temperature sensor measurements according to a first ambient temperature determination algorithm to compute the determined ambient temperature. During time intervals in which the processing system is operating in the second operating state, the processing system may process the temperature sensor measurements according to a second ambient temperature determination algorithm to compute the determined ambient temperature.
