Patent ID: 8682491

Claim:
An integrated energy management and device automation system for managing a premises electrical system having a plurality of electrical circuits, the energy management system comprising: a central controller operatively connected to the premises electrical system, the central controller being configured to receive, over the premises electrical system, energy usage data from a plurality of modules and to store the energy usage data on a storage device accessible to the central controller, and being further configured to receive module originated notifications that a module has been connected to the premises electrical system; the plurality of modules, each module comprising a processor, a powerline interface operatively connected to the processor and to one of the plurality of electrical circuits and a sensor operatively connected to the one of the plurality of electrical circuits so that the sensor can sense at least one of current and voltage, each module being configured to collect data relating to energy usage using the sensor and to transmit at least a portion of the data relating to energy usage to the central controller as energy usage data, each module also being configured to automatically send a notification of its presence to the central controller when the module is connected to the premises electrical system; and at least one of the plurality of modules being configured to control the operation of a controlled electrical device when the controlled electrical device is connected to the electrical circuit to which the at least one module is operatively connected.
