Abstract

A group of sensor devices is connected to the power line and configured for collecting power usage information and enabling power management to reduce the carbon foot print of the home, as well as to provide local area networking. In one embodiment of the invention, the devices include an intelligent master sensor and its sub-sets, such as a communication and power management sensor and a power control switch sensor. The master device is configured to collect, compile, and communicate the collected data via the web or other communication medium to the outside world. The master device also receives and distributes control instructions that are used to control the power usage via the associated switches in the home or office. The sensors are used in the home or office environment to provide integrated sensing and control of home power usage and power management, while establishing a LAN having communication capability, including streaming media delivery capability.
