Abstract:
A method and system is disclosed that includes a controller that determines a sleep schedule for reduced function devices on a home network. The devices have various sleep schedules in which to operate in an active state or a reduced function state. The controller determines the different schedules by sending communication messages to each device via a communication module. A timer is used to determine a sleep schedule for reduced function devices (RFDs) on the network. The sleep schedule is used to monitor when the devices are communicating on the network and are no longer able to communicate with the controller.
