Abstract: The present disclosure generally relates to wireless devices, and more particularly, to battery powered wireless devices and methods of operating said devices using a scheduled communication time. A first device and a second device of a building control system may communicate wirelessly during scheduled communication times. The second device may enter a listening state during the scheduled communication times, and may enter a non-listening state between at least some of the scheduled communication times. A plurality of user inputs may cause a corresponding communication between the first device and the second device. The user inputs may identify active periods of a day that user input is more likely to occur, and inactive periods of the day that user input is less likely to occur. The second device may be maintained in the listening state more during active periods than during inactive periods.
