A demand supply management system for an appliance receives information related to cost of energy use and communicates data to the associated appliance in response thereto. A single chip, light emitting diode (LED) device is preferably associated with a module or portion of the home appliance. The LED device conveys information relating to at least two of cost of energy use, signal strength, and module status. The LED device is preferably a single chip, single color solid-state LED device that is selectively actuated between “illuminated” and “non-illuminated” states, steady on, slow flash, fast flash, varying duration, intermittent “illuminated” and “non-illuminated”, etc. to convey information to the user.
