Abstract

A system and method of operating an energy data management and control system has a first communication network to transmit and receive data to and from a user interface, a second communication network to transmit and receive data to and from a Utility company, and a third communication network to access data from and provide data to accessories within a home. The system reformats the data from any of the first, second and third communication networks for communication with another of the first, second and third communication networks, wherein at least one of the communication networks operate on a protocol different from another one of the communications networks. The data defines various operations of the system.

Claims

1. A method, comprising:

receiving into a home energy gateway data generated from any one of a first communication network via a first interface channel to transmit and receive data to and from a user interface, a second communication network via a second interface channel to transmit and receive data to and from a utility company, and a third communication network via a third interface channel to access data from and provide data to accessories within a home; and

operating an energy data management control system using the data,

wherein the receiving of the data includes providing a price signal from the utility company to an appliance, receiving in the home energy gateway the price signal which includes a price schedule or a price change from the utility company via the second communication network, storing in the home energy gateway the price signal, reviewing scheduling priorities in the home energy gateway received from a user over the first interface channel, and sending a load shed command to the appliance based on the scheduling priorities and the price signal via the third interface channel.

2. The method of claim 1, wherein the receiving of the data includes receiving power consumption data from a smart meter for storage in a database of the home energy gateway.

3. The method of claim 2, wherein the receiving of the power consumption data includes:

setting up a timer in the home energy gateway;

periodically pinging the smart meter for the power consumption data via the second communication network; and

storing the power consumption data in the database of the home energy gateway.

4. The method of claim 1 wherein the receiving of the data includes generating a utility company direct load control command to a load control box on at least one accessory of the accessories.

5. The method of claim 1 wherein the receiving of the data includes obtaining data representing power consumption from at least one accessory of the accessories and storing the power consumption data of the accessory in a database of the home energy gateway.

6. The method of claim 1, further including configuring the energy data management control system to generate and deliver a daily power consumption cost chart to a remote device.

7. The method of claim 1, further including generating power consumption data from the home energy gateway and sending the generated power consumption data to an external server.

8. The method according to claim 1, further including generating a message from the utility company to a computer display, that is not part of the home energy gateway, but which is accessed via the first interface channel of the home energy gateway.

9. The method of claim 1, further including:

reformatting the data from any of the first, second and third communication networks for communication with another of the first, second and third communication networks, wherein at least one of the communication networks operate on a protocol different from another one of the communication networks.

10. A method comprising:

receiving into a home energy gateway data generated from any one of a first communication network via a first interface channel to transmit and receive data to and from a user interface, a second communication network via a second interface channel to transmit and receive data to and from a utility company, and a third communication network via a third interface channel to access data from and provide data to accessories within a home; and

operating an energy data management control system using the data,

wherein receiving of the data includes,

generating a utility company direct load control command to a load control box on at least one accessory of the accessories;

receiving, at the home energy gateway, a price signal which includes a price schedule or a price change for an appliance from the utility company over the second communication network via the second interface channel;

reviewing scheduling priorities in the home energy gateway received from a user over the first interface channel; and

sending a load shed command to a disconnect box of the accessory over the third communication network via the third interface channel.

11. The method of claim 10, wherein the receiving of the data includes providing a price signal from the utility company to an appliance.

12. An energy data management and control system configured to allow a user to configure operation of the energy data management and control system to generate and send a plurality of different messages, the system comprising:

a plurality of communication networks configured to transmit and receive data, the plurality of communication networks comprising a first communication network via a first interface channel configured to transmit and receive data to and from a user interface, a second communication network via a second interface channel configured to transmit and receive data to and from a utility company, and a third communication network via a third interface channel configured to access data from and provide data to accessories within a home, the first communication network, the second communication network, and the third communication network configured to operate via communication protocols distinct from one another; and

a home energy gateway configured as a single point of control and including a plurality of interface channels that correspond to the first interface channel, the second interface channel, and the third interface channel to enable communication by the plurality of communication networks to the home energy gateway,

wherein the user interface allows entry of instructions that control operation of the system by the entered instructions, and

wherein the home energy gateway is configured to;

provide a price signal from the utility company to an appliance, wherein the price signal includes a price schedule or a price change from the utility company via one of the plurality of communication networks,

store the price signal,

review scheduling priorities received from the user via the user interface, and

send a load shed command to the appliance based on the scheduling priorities and the price signal.

13. The system of claim 12 wherein the system is further configured to receive power consumption data from a smart meter for storage in a database of the home energy gateway.

14. The system of claim 12, wherein the home energy gateway is further configured to provide the utility company direct load control command to a load control box on at least one accessory of the accessories.

15. The system of claim 12, wherein the home energy gateway is further configured to obtain data representing power consumption from at least one accessory of the accessories and to store the power consumption data of the accessory in a database.

16. The system of claim 12, wherein the home energy gateway is further configured to generate and deliver daily power consumption cost chart to a remote device.

17. The system of claim 12, wherein the home energy gateway is further configured to generate power consumption data by the home energy gateway and to send the power consumption data to an external server.

18. The system according to claim 12, wherein the home energy gateway is further configured to display a message from the utility company on a computer display, that is not part of the home energy gateway, but is accessed via the home energy gateway.
