Identifying devices using power data and network data
Devices in a building may be identified using a combination of power monitoring and network monitoring. Power monitoring may be performed by obtaining a power monitoring signal and processing the power monitoring signal with models to determine information about one or more devices in the building. Network monitoring may be performed by receiving network packets transmitted by devices in the building and processing the data of the network packets to determine information about one or more devices in the building. For some devices and some implementations, information about a device may be determined by using both power monitoring and network monitoring.
