Identifying device state changes using power data and network data

A system for determining states of devices in a building, the system comprising:

• at least one computer comprising at least one processor and at least one memory, the at least one computer configured to:
• obtain a power monitoring signal by measuring an electrical property of a power line in the building, wherein the power line provides power to the devices in the building, the devices in the building comprising a first device and a second device;
• determine a state of the first device by (1) processing a first power event the power monitoring signal with a plurality of power models to generate a score for each power model of the plurality of power models, and (2) selecting a state of the first device from a plurality of possible states using the scores;
• receive first network data from a second server computer, wherein the second server computer transmitted the first network data based on information received from the second device;
• determine, using the first network data, that the first network data corresponds to the second device;
• and
• select, using the first network data, a state of the second device from a plurality of possible states for the second device.

One or more non-transitory computer-readable media comprising computer executable instructions that, when executed, cause at least one processor to perform actions comprising:

• obtaining a power monitoring signal by measuring an electrical property of a power line in a building, wherein the power line provides power to devices in the building, the devices in the building comprising a first device and a second device;
• determining a state of the first device by (1) processing a first power event in the power monitoring signal with a plurality of power models to generate a score for each power model of the plurality of power models, and (2) selecting a state of the first device from a plurality of possible states using the scores;
• receiving a first network packet, wherein the first network packet was transmitted by the second device;
• determining, using information in the first network packet, that the first network packet was transmitted by the second device;
• and
• selecting, using the information in the first network packet, a state of the second device from a plurality of possible states for the second device.
