Abstract
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.
