Abstract
A controller in communication with one or more energy consuming appliances for a premises includes a transmitter device for transmitting wireless signals to a utility meter to request an energy consumption reading, and a receiver device to receive wireless signals including energy consumption information. The controller is configured to receive a signal from an energy consuming appliance indicating the appliance was actuated, and to responsively transmit a signal to the utility meter to request an energy consumption reading and thereafter receive a signal including an energy consumption value. Following deactivation of the appliance, the controller is configured to transmit a signal to the utility meter to request an energy consumption reading, and thereafter receive a signal from the meter including another energy consumption value. The controller is configured to determine from a difference between the energy consumption values an estimate of the energy consumption level associated with the appliance.
