Abstract:
1. A system which controls appliances comprising: at least one first transceiver identified by an identification code and configured to receive a radio frequency (RF) demand reduction control signal having the identification code; at least one appliance controller unit, the appliance controller unit coupled to at least one appliance and the first transceiver; an appliance controller unit memory residing in the appliance controller unit, the appliance controller unit memory configured to have a unique identification code identifying the appliance controller unit such that when, the RF demand reduction control signal identification code corresponds to the appliance controller unit unique identification code, the appliance coupled to the appliance controller unit is shut off; a second transceiver coupled to a meter, the meter coupled to the appliance, and the second transceiver configured to generate a second RF signal corresponding to an amount of demand detected by the meter; and a plurality of network transceivers configured to communicate the second RF signal to an energy management controller that initiated the RF demand reduction control signal; wherein the energy management controller determines a change in the demand detected by the meter before transmission of the demand reduction control signal and after the received RF signal corresponding to an amount of demand detected by the meter.
