A method and system for communicating with an associated home appliance having a micro-controller includes providing a master device that emits a signal in response to data indicative of energy operational costs. One or more RFID tags receive the master device signal. The RFID tag(s) are connected to the associated home appliance micro-controller to control the operational mode of the home appliance. Preferably, four RFID tags are responsive to four distinct frequency signal emitted by the master device and are representative of different modes of operation for the associated home appliance.

1. A method comprising: emitting a first signal and a second signal from a master device in response to data indicative of energy operational costs, the first signal and the second signal having, respectively, a first frequency and a second frequency, wherein the first frequency is different from the second frequency; andreceiving the first signal and the second signal at a home appliance incorporating a first RFID tag and a second RFID tag responsive to, respectively, the first frequency of the first signal and the second frequency of the second signal to control operation of the home appliance. 2. The method of claim 1, wherein one of the first RFID tag and the second RFID tags are an active RFID tag having a memory for storing data therein. 3. The method of claim 2 further comprising selectively manipulating the data in the active RFID tag by the master device. 4. The method of claim 1, further comprising providing a third RFID tag and a fourth RFID tag in communication with the associated home appliance controller, wherein the third RFID tag and the fourth RFID tag resonate at frequencies that are different from each other and from the first RFID tag and the second RFID tag. 5. The method of claim 4, further comprising emitting a third signal and a fourth signal from the master device at, respectively, a third frequency and a fourth frequency for communicating with the third RFID tag and the fourth RFID tags, respectively. 6. The method of claim 5 wherein the first RFID tag, the second RFID tag, the third RFID tag, and the fourth RFID tag are passive tags and wherein the first signal, the second signal, the third signal, and the fourth signal are representative of low, medium, high, and critical modes of operation for the associated home appliance. 7. A system comprising: a master device adapted to receive data relating to energy cost and for emitting a first signal at a first frequency and a second signal at a second frequency indicative of same;a home appliance incorporating a first RFID tag and a second RFID tag responsive to, respectively, the first frequency of the first signal and the second frequency of the second signal to control operation of the home appliance from the master device, the appliance also comprising a microcontroller,wherein the microcontroller changes operation of the home appliance between a first state and a second state in accordance with the response to the first signal by the first RFID tag and the response to the second signal by the second RFID device. 8. The system of claim 7, wherein one of the first RFID tag and the second RFID tag is an active tag having a memory that is selectively altered in response to the first signal and the second signal from the master device. 9. The system of claim 7, wherein the second RFID tag comprises a passive device operatively associated with the microcontroller. 10. The system of claim 7, further comprising a third RFID tag and a fourth RFID tag operatively associated with the microcontroller, wherein the third RFID tag and the fourth RFID tag are responsive to a third signal at a third frequency and a fourth signal at a fourth frequency from the master device, wherein the microcontroller changes operation of the home appliance between a third state and a fourth state in accordance with the response to the third signal by the third RFID tag and the fourth signal by the fourth RFID tag. 11. The system of claim 10, wherein the first state, the second state, the third state, and the fourth state represent one of low, medium, high and critical modes of operation for the home appliance. 12. The system of claim 9, wherein the first frequency, the second frequency, the third frequency, and the fourth frequency are different from one another. 13. The system of claim 9, wherein the first state and second state define operation of the home appliance in different energy saving operational modes.
