Abstract

A wireless tracking device for monitoring usage patterns and power consumption of appliances such as a refrigerator. The power consumption is monitored by the use of new and innovative wireless tracking device that is placed by a user inside the appliance while it is operational. Appliance usage pattern information and power consumption information is communicated by the wireless tracking device and is collected by an intelligent power hub (and in some embodiments, an energy pump device, an intelligent power meter or a collector device). User behavior is modified by recommending approaches to cut power consumption by the appliances thereby providing savings and reducing the cost of operation.

tracking an appliance usage information, by a tracking device located inside the appliance, wherein the tracking device is placed inside the appliance and wherein the tracking device is communicatively coupled to an external collector unit;

reporting, by the tracking device, the appliance usage information to the collector unit, wherein the collect unit is external to the appliance and is located in the same premises as the appliance;

correlating, by the collector unit, the number of times the appliance is used and the duration of such usage, with an energy consumption data computed or collected for the appliance;

making energy saving recommendations, by an advisory unit communicatively coupled to the collector unit and the tracking device, for efficient usage of the appliance.

2. The method of claim 1 wherein the appliance is a refrigerator that comprises at least one refrigerator door and wherein the tracking device tracks the closing and opening of the at least one refrigerator door, the number of times the at least one refrigerator door is opened, the duration for which it is opened, and the temperature inside the refrigerator at various times.

3. The method of claim 1 wherein the correlating unit and the advisory unit are combined into a power usage monitoring unit that is communicatively coupled to the tracking device while also being electrically coupled to the appliance via a smart power socket that is managed by the power usage monitoring unit.
