Abstract: The present disclosure includes a thermostat for controlling HVAC equipment of a building based on occupancy of the building. The thermostat includes an occupancy sensor configured to detect a presence of an occupant. The thermostat includes a processing circuit. The processing circuit can receive occupancy data for one or more points in time from an occupancy sensor. The occupancy data indicates the presence of an occupant at the one or more points in time. The a processing circuit can train an occupancy model based on the occupancy data, wherein the occupancy model predicts a probability of the presence of the occupant

Abstract: A thermostat is disclosed. The thermostat can include one or more temperature sensors configured to measure one or more temperature values. The thermostat can include a processing circuit. The processing circuit can receive the one or more temperature values from the one or more temperature sensors. The processing circuit can receive one or more central processing unit (CPU) usage values, wherein the one or more CPU usage values indicate computing usage of the processing circuit. The processing circuit can determine, based on an empirical model comprising one or more gain values and one or more filters and based on one or more signals, a temperature of the building. The one or more signals comprise the one or more temperature values and the one or more CPU usage values. The empirical model accounts for dynamics of heat generated by the processing circuit and airflow acting on the thermostat.

Abstract: A thermostat for a building space is disclosed. The thermostat can include a processing circuit. The processing circuit can cause building equipment to heat or cool the building space via one or more heating outputs or one or more cooling outputs. The processing circuit can record the length of time that the processing circuit causes the building equipment to heat or cool the building space. The processing circuit can simulate a thermal plant model to determine a simulated runtime, wherein the thermal plant model is a thermal plant model of the building space and the building equipment. The processing circuit can determine a number of hours saved based on the simulated runtime and the recorded length of time

Abstract: A thermostat is disclosed. The thermostat can include one or more temperature sensors configured to measure a plurality of temperature values within a building. The thermostat can include a processing circuit coupled to the one or more temperature sensors. The processing circuit can receive the plurality of measured temperature values from the one or more temperature sensors. The processing circuit can determine, based on a time invariant Non-Linear Least Squares (NLSQ) technique and the plurality of measured temperature values, a compensated temperature value within the building, wherein the compensated temperature value accounts for an unknown temperature state of the thermostat when the thermostat is turned on.
