Keep alive method for RFD devices
First Claim
1. A method for a network controller of a home energy management system with at least one memory storing executable instructions for the method, comprising:
- sending a communication message to one or more reduced function devices communicatively connected to the home network;
retrieving an application level response or acknowledgement from the one or more reduced function devices of the home network; and
determining a sleep schedule for each of the reduced function devices communicatively connected on the home network.

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.

8. A method for an energy management system comprising a controller of a home network of a home with at least one memory storing executable instructions for the method, comprising:
-
sending a first communication message that requests an application level response to one or more reduced function devices communicatively connected to the home network by the controller; initiating a time sequence of a timer; retrieving the application level response from the one or more reduced function devices of the home network; storing in the memory a time from the timer that the application level response is retrieved for each of the reduced function devices that the response is retrieved from; and sending a second communication message with an application level response request with a time out value to the one or more reduced function devices of the network from which the application level response is retrieved from. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An energy management system for a home area network (HAN) having managed reduced function devices for a home that respectively draw different amounts of power from a source of power, the system comprising:
-
a power/energy measuring device in communication with the managed devices that provides an energy/power consumption measurement for the home; a controller that is in communication with the reduced function devices and having a memory for storing sleep schedules of each reduced function device, comprising; a first communication module that is in communication with the power/energy measuring device; a second communication module that is in communication with the reduced function devices of the home and configured to retrieve an application level response from the devices in response to a communication message sent therefrom; and a timer that clocks a sleep time for each device depending upon the application level response retrieved; wherein the central controller is configured to monitor and manage energy consumption of each of the reduced function devices by sending communications to each of the devices to determine a sleep schedule respectively. - View Dependent Claims (16, 17, 18, 19, 20)
