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.

Abstract: The various implementations described herein include methods, devices, and systems for determining locations of a plurality of electronic devices within a home. In one aspect, a method is performed at a computing system having one or more processors and memory. The method includes: (1) obtaining device identification information for a plurality of electronic devices; (2) broadcasting, via a standard wireless communication protocol, a request based on the device identification information that a particular electronic device of the plurality of electronic devices be enabled to transmit or reflect location information using a radar technique; (3) receiving a signal from the particular electronic device, the signal indicating a location of the particular electronic device using a radar technique; and (4) determining the location of the particular electronic device based on the received signal.

Abstract: A smart-home device may include an energy-storage element that stores energy that is harvested from an environmental system and a solid state relay (SSR) switching integrated circuit (IC). The SSR switching IC may include switching elements that operate in a first state and a second state. The IC may also include a control circuit that causes the switching elements to operate in the first state to activate a function of the environmental system until the energy-storage element has dropped below a threshold. The control circuit may also cause the switching elements to operate in the second state and harvest energy from the environmental system, determine that a first time has elapsed since the switching elements began operating in the second state, and cause the one or more switching elements to again operate in the first state.

Abstract: A thermostat may include HVAC wire connectors that receive a call relay wire and a power return wire, switching elements having a first operating state in which they create a connection between the call relay wire and the power return wire and a second operating state in which the connection between the call relay wire and the power return wire is interrupted. The thermostat may also include control circuitry configured to cause the switching elements to operate in the first operating state to actuate an HVAC function; detect an anomaly associated with measurements from power monitoring circuitry; cause the switching elements to continue to operate in the first operating state until a zero-crossing is detected; and then cause the one or more switching elements to operate in the second operating state.

Abstract: A thermostat may include first and second solid-state switching elements coupled to a call relay wire connector and a power return wire connector. The switching elements may be configured to operate in a first state to make a connection between the call relay wire connector and the power return wire connector, and a second state in which the connection is interrupted. The thermostat may also include power monitoring circuitry configured to cause the switching elements to operate in the first state to actuate an environmental control function, receive an indication that the switching elements should transition to the second state, at a first time after receiving the indication, turn off whichever of the first switching element and the second switching element receives AC current from the environmental control system at the first time; and at a second time after the first time, turn off the other of the switching elements.
