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.

Identifying devices using power data and network data

Devices state changes in a building may be determined 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 state changes of one or more devices in the building. Network monitoring may be performed by receiving information about network packets transmitted by devices in the building and processing the information about the network packets to determine information about state changes of one or more devices in the building. For some devices and some implementations, information about state changes of a device may be determined by using both power monitoring and network monitoring.

Identifying device state changes using power data and network data

A system for determining states of devices in a building includes an electrical main, an electrical panel that distributes power to the devices, a power meter that measures power consumed by the devices from the electrical main, and a first sensor configured to measure an electrical property of the electrical main. The system further includes a computer configured to determine a state of a first device in the building by processing a first power event in a power monitoring signal, obtained from the first sensor, to generate a score for each of a plurality of power models, and to select the state of the first device using the scores. The computer is further configured to receive a first network packet transmitted by a second device in the building; determine that the first network packet was sent by the second device; and select the state of the second device.

A power monitor may have more than one mode of operation to provide improved functionality for end users. For example, a first mode of operation may provide higher accuracy in determining information about devices but may also have higher latency in making determinations (e.g., identifying state changes of devices), and a second mode of operation may have lower accuracy but also lower latency to provide information more quickly to end users. The mode of operation of the power monitor may change depending on whether an end user is currently viewing information about devices. When a user is not viewing information about devices, the power monitor may operate in a first mode of operation (e.g., to improve accuracy), and when a user is viewing information about devices, the power monitor may operate in a second mode of operation (e.g., to provide updates more quickly).

Power monitor with multiple modes of operation

Devices state changes in a building may be determined 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 state changes of one or more devices in the building. Network monitoring may be performed by receiving information about network packets transmitted by a device in the building and processing the information about the network packets to determine information about a different device or a state change of a different device in the building. For some devices and some implementations, information about state changes of a device may be determined by using both power monitoring and network monitoring.

Electrical usage of devices in a building may be monitored to provide information about the operation of the devices to a user. The information communicated to a user may include historical information that is retrieved from a server and real-time information that is received from a power monitoring device. The historical information may be transmitted to the user device over a first network connection where the historical information is retrieved using an identifier received from the user device. The real-time information may be received from a power monitoring device and transmitted to the user device over a second network connection.

Communication of historical and real-time information about devices in a building

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 information about network packets transmitted by devices in the building and processing the information about 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. The information about a device may include, for example, a type (e.g., a dishwasher), make, or version of a device.

Power models may be used to identify devices in a building or state changes of devices in a building by processing a power monitoring signal with the power models. A power model for a device may be trained using examples of power monitoring signals corresponding to that device, and network monitoring may be used to identify training data for training power models for that device. Network monitoring may include receiving information about network packets transmitted by devices in the building and processing the information about the network packets to determine information about a state change of a first device in the building at a first time. A portion of the power monitoring signal that includes the first time may then be used to train a power model for the first device. The trained power model for the first device may then be deployed to a building where it used to perform power monitoring of the first device.

Training power models using network data

Electrical usage of devices in a building may be monitored to provide information about the operation of the devices to a user. The information communicated to a user may include historical information and real-time information. In determining the real-time information, it may be desired to provide the information quickly and use a smaller set of features that are available more quickly. In determining the historical information, it may be desired to provide more accurate information and use a larger set of features. A device may compute real-time information and historical information using different sets of features.

Determining information about devices in a building using different sets of features

Electrical usage of devices in a building may be monitored to assist a user in labeling devices. In some implementations, a user may provide information about a first device, and this information may be used to obtain a plurality of mathematical models that each correspond to a device or a class of devices. The mathematical models may be used to process an electrical signal, and a score may be generated for each mathematical model. A mathematical model may be selected from the plurality of mathematical models using the scores, such as selecting a mathematical model with a highest score. The first device may be associated with the selected mathematical model.

Assisted labeling of devices with disaggregation

Electrical usage of devices in a building may be monitored to assist a user in labeling devices. In some implementations, an electrical signal corresponding to devices may be processed with models to determine first information about a device, and this first information may be presented to a user to receive second information about the device from the user. The device may then be labeled using the second information from the user. In some implementations, a user may provide first information about a device, and the first information may be used to obtain models for processing an electrical signal. A model may be selected from the obtained models by comparing the obtained models to an electrical signal. The device may then be labeled using the selected model or the first information.
