Abstract: A smart-home device may include a temperature sensor, energy-consuming subsystems, and processors programmed to receive a temperature measurement from the temperature sensor for an ambient environment surrounding the temperature sensor; receive inputs from the energy-consuming subsystems that indicate power-consuming activities of the energy-consuming subsystems; providing the inputs from the energy-consuming subsystems to a model that is trained to calculate an effect of the power-consuming activity of the energy-consuming subsystems on the temperature measurement from the temperature sensor; and calculating an estimate of the temperature of the ambient environment by compensating the temperature measurement from the temperature sensor with using the effect of the power-consuming activity of the energy-consuming subsystems.

Abstract: A method of powering a controller using an intermediate device with power from an environmental system may include receiving current from a power wire from the environmental system; passing the current from the power wire to a second command wire from the controller; monitoring the current flowing between the power wire and the second command wire while the current is below a threshold indicative of an amount of current used to power the controller from the environmental system; detecting when the current flowing between the power wire and the second command wire exceeds the threshold indicating that the controller is sending a command to the environmental system to perform the function; and sending a command to environmental system using a first command wire from the environmental system after detecting that the current exceeds the threshold.

Abstract: A thermostat for controlling an HVAC system includes wiring terminals adapted and configured to make an electrical connection with an HVAC system wires such as common, heating and cooling control and return wires. The making of the connection with a common wire actuates switching open a loop of an electrical circuit used for power harvesting. The wiring terminal includes actuation of a moveable part of the terminal so as to accommodate the common wire that in turn actuates the switching open the power harvesting loop. More than one other loop can be switched. The wiring terminal can be used to automatically connect and/or disconnect Rc and Rh circuits when one or both Rc and Rh wires are present. The wiring terminal can be used for electronically sensing the presence of the HVAC system wire.

Abstract: A method may include operating a switching circuit in an on state and an off state to actuate a flow of electrical power through a load when switched to the on state; monitoring an electrical property associated with the switching circuit; receiving an enable signal from a processor to power the load; providing a drive signal to the switching circuit to switch to the on state and power the load; determining if an electrical anomaly is present based on the monitored electrical properties; causing the switching circuit to switch to the off state if an electrical anomaly is detected; providing a fault signal to the processor; determining while the switching circuit is off, if the electrical anomaly has been corrected; and after the anomaly has been corrected, causing the switching circuit to switch to the on state.
