摘要:
An electrical panel or an electrical meter may provide improved functionality by interacting with a smart plug. 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.
摘要:
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.

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.

摘要:
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).
摘要:
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.
摘要:
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.
