Claim 6:
7. A method for determining an actual ambient temperature value associated with a measured ambient temperature in a building control system, the method comprising:
obtaining a first temperature measurement from a first temperature sensor of a device, the first temperature sensor configured to sense the measured ambient temperature;
obtaining a second temperature measurement from a second temperature sensor of the device, the second temperature sensor configured to measure a temperature of a processing circuit of the device;
determining a brightness level associated with a display of the device;
determining a state of a relay associated with the device, the state of the relay indicative of a level of electrical energy powering the device;
providing the first temperature measurement, the second temperature measurement, the brightness level, and the state of the relay as input to a neural network;
determining the actual ambient temperature value associated with the measured ambient temperature based on an output of the neural network; and
determining, by the neural network, an internal heat index associated with the device using the second temperature measurement, the brightness level, and the state of the relay, wherein the internal heat index comprises an estimation of heat generated by electronic components of the device, wherein the output of the neural network comprises a weighted sum of the first temperature measurement and the internal heat index.
