Abstract: A smart-home device may include a main power rail that provides power to components of the smart-home device; an integrator coupled to the main power rail that stores energy on an energy-storage device, where the energy stored on the energy-storage device is representative of an amount an amount of power provided to the smart-home device through the main power rail during an integration cycle of the integrator; and a counter that stores a number of integration cycles performed by the integrator during a time interval, where a total amount of power provided to the smart-home device through the main power rail during the time interval is represented by: (1) the number of integration cycles performed by the integrator during the time interval; and (2) the energy stored on the energy-storage device.

Abstract: A smart-home device may include an energy-storage element that stores energy harvested from an environmental system; a power wire connector and a return wire connector; and switching elements configured to operate in a first state where the switching elements create a connection between the power and the return; and a second state where the switching elements interrupt the connection between the power and return. The smart-home device may also include a circuit that controls the switching elements, where the circuit is configured to detect a zero-crossing of a current received through the power wire connector; wait for a first time interval after the zero-crossing is detected; after an expiration of the first time interval, enable active power stealing for a second time interval; and after an expiration of the second time interval, disable active power stealing.
