Networked Device with Power Usage Estimation
First Claim
1. A method of reporting energy usage status by a networked device comprising:
- receiving a request for energy usage status from a network;
retrieving a set of power usage data from a non-volatile memory located within the networked device, the power usage data having been previously stored in the non-volatile memory;
calculating a best estimate of the energy usage status based on the set of power usage data retrieved from the non-volatile memory; and
sending the best estimate of the energy usage status by the networked device over the network as a reply to the energy usage status request.

Abstract
A method and apparatus for a networked device to estimate its own power or energy usage, and report it over a network is disclosed. The method of reporting energy usage status by the networked device comprises receiving a power usage status request from a network, retrieving a set of power usage data from a non-volatile memory located within the networked device, the power usage data having been previously stored in the non-volatile memory, calculating a best estimate of the energy usage status on the set of power usage data retrieved from the non-volatile memory, and sending the best estimate of the energy usage status over the network as a reply to the power usage status request. A log of time spent in the different operating conditions by the networked device may be maintained, and the best estimate of the energy usage status calculated based on both the set of power usage data and the log of time spent in the different operating conditions. The networked device disclosed comprises, means for connecting to a network, means for storing a set of power usage data, and means for calculating a best estimate of the energy usage status based on the set of power usage data. An energy usage status request is received from the network and the best estimate of the energy usage status is sent in a response message over the network. The networked device may be a networked light bulb.

23. A networked light bulb comprising:
-
a light emitting apparatus; a controller; a non-volatile memory communicatively coupled to the controller, a set of power usage data held in the non-volatile memory; and a network adapter communicatively coupled to the controller;
whereinthe network adapter receives an energy usage status request from the network and communicates it to the controller; the controller retrieves the set of power usage data from the non-volatile memory, calculates a best estimate of the energy usage status based on the set of power usage data, and communicates the best estimate of the energy usage status to the network adapter; and the network adapter sends a message over the network containing the best estimate of the energy usage status. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
