Appliance monitoring and control systems

摘要

We describe a system to provide feedback to a user of an appliance for energy saving, the system comprising: means for monitoring an energy consumption of the appliance; means for inferring a mode of use of the appliance from said power consumption; and means for providing feedback to said user responsive to said inferred mode of use to indicate how an amount of energy used by said appliance may be reduced. In some embodiments the means for monitoring power consumption comprises means for identifying one or more periods of operation of the appliance from data representing aggregate power consumption of a plurality of devices including the appliance. In embodiments the means for monitoring the power consumption comprises means for monitoring mains electricity power consumption of the plurality of devices. Alternatively the means for monitoring the power consumption may comprise, for example, a plug-through power sensing device.

主权项

1. A system to provide feedback to a user of an appliance for energy saving, the system comprising a processor and code disposed in memory for execution by the processor, the code configured, when executed, for:
monitoring an energy consumption of the appliance; inferring a mode of use of the appliance from said power consumption wherein said inferred mode of use comprises one of: an inferred amount of water heated by said appliance, and a temperature to which water is heated by said appliance; and providing feedback to said user responsive to said inferred mode of use to indicate how an amount of energy used by said appliance may be reduced.
