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.

Abstract: A smart-home device may include wire connectors that couple to an inductive power coil and a load, one or more solid-state switching elements having a first operating state in which they create a connection between the wire connectors and a second operating state in which the connection is interrupted. The smart-home device may cause the switching element(s) to operate in the first operating state to power the load; detect an anomaly from measurements from power monitoring circuitry; cause the switching element(s) to operate in the second operating state for at least a first time interval; and after the expiration of the first time interval, cause the one or more switching elements to operate in the first operating state and determine whether the anomaly is still present.

Abstract: A method of automated sensing of an electrical anomaly associated with a thermostat may include switching a switching circuit within the thermostat to an on state. The switching circuit may be configured to activate an HVAC function when switched to the on state. The method may also include monitoring one or more electrical properties associated with the switching circuit. The method may additionally include determining if an electrical anomaly is associated with the switching circuit based at least in part on the monitored one or more electrical properties. The method may further include switching the switching circuit to an off state if an electrical anomaly is detected.
