The present invention relates to a home energy management apparatus and method for providing a single point of connection between the power devices on the home network and the service portal server of the energy service provider. More specifically, the home energy management device for transmitting the energy information of the various power devices on the home network to the service portal server of the energy service provider and the event information from the service portal server of the energy service provider to control the power devices on the home network And to a method thereof.

In the power industry, the one-way flow of electrical energy from energy service providers to power consumers is driving a paradigm shift from the energy service provider to the power system, called the Smart Grid, which allows two-way exchange of information between energy service providers and consumers. To do this, the power devices on the home network are automatically linked to reduce or cut off power consumption according to the change in the electricity bill or the reliability of the power system.The real-time power consumption information of the power devices on the home network is delivered to the energy service provider to control the power supply. It needs to be used for power system operation. In other words, a home energy management device and a home energy management system are required in which power devices on a home network and a service portal server of an energy service provider can be linked to each other logically and physically so that the power system can be efficiently operated.

Currently, energy service providers, including utilities, collect energy information from electricity consumers that are limited to the energy consumption of electricity consumers by manual inspection by the meter reader, and use the collected information only for electricity billing.
