    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: An electronic device is located in a room. The device has a casing, a first processor coupled to a radar transceiver, a second processor coupled to a motion sensor, and memory. Using the second processor, the device determines using signals from the motion sensor whether an object is in proximity. In accordance with a determination that the object is in proximity, the device wakes up the first processor. Using the first processor, the device enables operation of the radar transceiver. It determines using signals from the radar transceiver whether the object is in contact with the casing. In accordance with a determination that the object is in contact with the casing, the device identifies an input command based on at least one of: a location of the object, and a movement of the object, and adjusts operation based on the input command.
