Abstract
An intelligent thermostat communicates with battery-powered threat detectors, such as smoke detectors, to allow remote quieting and coordination of a low battery warning detected by the threat detector. In one embodiment, the threat detector transmits a pre-warning signal to the thermostat indicating that a low battery condition is imminent. The thermostat uses this information to display a pre-warning to the consumer so that the consumer may better coordinate replacing of the battery at a convenient time. Once a low battery condition has been detected, the threat detector transmits a low battery warning signal to the thermostat. The thermostat then displays a warning message and an option for the consumer to quiet the chirping for a period of time from the thermostat. Preferably, the thermostat automatically quiets the chirping during quite times so as to not disturb the consumer.
