Abstract
A smart-home device may include a solid state relay (SSR) switching integrated circuit (IC). SSR switching IC may include switching elements configured to open and close a connection between a power wire and a return wire of an environmental system; a voltage sensor that measures a voltage across the one or more switching elements; a current sensor that measures a current through the one or more switching elements; and a temperature sensor that measures a temperature near the one or more switching elements. The smart-home device may also include a wireless communication device that periodically receives voltage, current, and temperature data originating from the SSR switching IC and transmits the voltage, current, and temperature data to a device management server. The device management server may receive batches of voltage, current, and temperature data from a plurality of smart-home devices.
