First Claim
1. A system, comprising:
- a plurality of conductors configured to couple with one or more sensors, wherein the sensors are configured to measure a plurality of electrical load characteristics in one or more electrical power line circuits of a building;
an analog-to-digital converter coupled to the plurality of conductors, the analog-to digital converter configured to receive signals corresponding to the plurality of electrical load characteristics from the one or more sensors and convert the signals from analog signals to digital signals; and
one or more remote processors, coupled to the analog-to-digital converter, configured to;
receive, from the analog-to-digital converter, one or more of the digital signals corresponding to the plurality of electrical load characteristics;
perform digital signal processing on at least one of the one or more digital signals; and
determine, based on the digital signal processing, an electrical signature for at least one electrical device receiving power from at least one of the one or more electrical power line circuits, wherein the electrical signature comprises at least a phase angle and a frequency harmonics of the power being received; and
identify the at least one electrical device based on the electrical signature of the at least one electrical device.

Abstract
A system for providing information about electrical devices in a residence includes a power measurement device, an electrical device identification component, and a notification component. The power measurement device measures characteristics of electrical power in one or more electrical power lines in the residence. Based on the measured electrical characteristics, the electrical device identification component determines electrical signatures specific electrical devices at the residence that are receiving electrical power through the electrical power lines, associates the electrical devices with a device type, and groups the electrical devices into zones of the residence. Based on power consumption by the specific electrical devices, the notification component determines events or conditions associated with specific electrical devices (for example abnormal usage, device failure, excess power consumption). Notifications relating to at least one of the events or conditions associated with the specific electrical devices are provided to a person associated with the residence (for example, homeowner or other resident).
