Various methods, systems, and devices for identifying a condition of a battery-powered device are presented. For example, a device may include a smoke detection sensor that detect smokes and, in response to detecting smoke, generate a smoke detection signal. The device may include test circuitry that tests an aspect of the battery-powered device. The device may include an audio output device that outputs a sound in response to the test circuitry determining a particular condition is present. The device may include a proximity detector that monitors for a wave movement of an object within a distance of the battery-powered device and generates a proximity detection signal when the proximity detector detects the wave movement performed by the object within the distance of the smoke detector device.
