US Patent 9152737 Providing notifications to a user

Electrical usage of devices in a building may be monitored to determine information about the operation of the devices in the building, and the information about the devices in the building may be used to provide notifications to a user. An electrical signal may be processed to determine a state change of a device. A notification score may then be determined using information about the state change of the device and a notification event model. A notification may then be sent to the user based at least in part on the notification event score.
