Abstract: According to one embodiment, a thermostat includes a main body, a rotatable input component that is rotatably coupled with the main body, and a rotation detection system that is configured to sense user rotation of the rotatable input component. The rotatable input component is configured to be rotated by a user to enable the user to provide input to the thermostat. The rotation detection system includes a magnetic component that is positioned on an inner surface of the rotatable input component and that is magnetized so as to have a plurality of alternating north and south magnetic regions. The rotation detection system also includes a sensor that is positioned adjacent the magnetic component. The sensor is configured to detect polarity changes as the rotatable input component and magnetic component are rotated relative to the sensor.

Abstract: A thermostat may include a plurality of heat-generating components; 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; a second temperature sensor that is disposed away from the plurality of heat-generating components; and a memory device storing a coefficient matrix. The thermostat may also include one or more processors that combine a plurality of inputs to calculate an ambient temperature for an enclosure in which the thermostat is installed, the plurality of inputs including readings from the plurality of first temperature sensors, readings from the second temperature sensor, and the coefficient matrix.

Abstract: A smart-home device may include a user interface having a first operating mode and a second operating mode, and a four-channel thermopile. A processing system may be programmed to receive an indication of a user presence near the smart-home device from the thermopile, and determine a motion signature based on the responses from the thermopile. The processing system may also be programmed to process the determined motion signature to determine the presence of a condition warranting user interface entry into the first mode from the second mode, and cause the user interface to transition from the first mode to the second mode based on the determined motion signature.
