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.
Claims20
A computer-implemented method for determining that a first device is connected to a smart plug, the method comprising:
- establishing a network connection with the smart plug, wherein the smart plug provides power to one or more devices;
- receiving a smart-plug power monitoring signal via the network connection, wherein the smart-plug power monitoring signal indicates an amount of power provided by the smart plug to the one or more devices;
- obtaining a first-main power monitoring signal using measurements from a sensor that measures an electrical property of a first electrical main of a building;
- identifying a smart-plug power event in the smart-plug power monitoring signal, wherein the smart-plug power event corresponds to an event time;
- determining that a first-main power event in the first-main power monitoring signal corresponds to the smart-plug power event in the smart-plug power monitoring signal using the event time;
- determining that the first-main power event corresponds to the first device by processing the first-main power event with a plurality of power models;
- determining that the first device is connected to the smart plug using the determination that the first-main power event corresponds to the first device;
- updating an entry in a data store to indicate that the first device receives power from the smart plug.
A system for determining that a first device is connected to a smart plug, the system comprising:
- at least one computer comprising at least one processor and at least one memory, the at least one computer configured to:
- establish a network connection with the smart plug, wherein the smart plug provides power to one or more devices;
- receive a smart-plug power monitoring signal via the network connection, wherein the smart-plug power monitoring signal indicates an amount of power provided by the smart plug to the one or more devices;
- obtain a first-main power monitoring signal using measurements from a sensor that measures an electrical property of a first electrical main of a building;
- identify a smart-plug power event in the smart-plug power monitoring signal, wherein the smart-plug power event corresponds to an event time;
- determine that a first-main power event in the first-main power monitoring signal corresponds to the smart-plug power event in the smart-plug power monitoring signal using the event time;
- determine that the first-main power event corresponds to the first device by processing the first-main power event with a plurality of power models;
- determine that the first device is connected to the smart plug using the determination that the first-main power event corresponds to the first device;
- update an entry in a data store to indicate that the first device receives power from the smart plug.
One or more non-transitory, computer-readable media comprising computer executable instructions that, when executed, cause at least one processor to perform actions comprising:
- establishing a network connection with a smart plug, wherein the smart plug provides power to one or more devices;
- receiving a smart-plug power monitoring signal via the network connection, wherein the smart-plug power monitoring signal indicates an amount of power provided by the smart plug to the one or more devices;
- obtaining a first-main power monitoring signal using measurements from a sensor that measures an electrical property of a first electrical main of a building;
- identifying a smart-plug power event in the smart-plug power monitoring signal, wherein the smart-plug power event corresponds to an event time;
- determining that a first-main power event in the first-main power monitoring signal corresponds to the smart-plug power event in the smart-plug power monitoring signal using the event time;
- determining that the first-main power event corresponds to a first device by processing the first-main power event with a plurality of power models;
- determining that the first device is connected to the smart plug using the determination that the first-main power event corresponds to the first device;
- updating an entry in a data store to indicate that the first device receives power from the smart plug.
