Abstract
A power monitor in a building processes a power monitoring signal obtained from the power line to the building to identify electrical events corresponding to state changes of devices in the building. The electrical event may be processed with a classifier to determine if the electrical event corresponds to a state change of an identified device from a list of identified devices or corresponds to a state change of an ambiguous device that is not from the list of identified devices. The power monitor may also determine power consumption information about individual identified devices and about groups of devices, such as a group of always on devices, a group of ambiguous devices, and categories of the group of ambiguous devices. Information about state changes of devices and power consumption of individual devices and groups of devices may be transmitted to a user device for presentation to a user.
