Abstract: 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).

Abstract: 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.

Abstract: A smart plug may provide a smart-plug power monitoring signal that includes information about power consumption of devices connected to the smart plug. The smart-plug power monitoring signal may be used in conjunction with power monitoring signals from the electrical mains of the building for providing information about the operation of devices in the building. For example, the power monitoring signals may be used to (i) determine the main of the house that provides power to the smart plug, (ii) identify devices receiving power from the smart plug, (iii) improve the accuracy of identifying device state changes, and (iv) train mathematical models for identifying devices and device state changes.

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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
