Apparatus for controlling an electrical device by remote control including a control device coupled to the electrical device by a wire connection for providing power to the electrical device, the control device having an actuator for adjusting the status of the electrical device and a radio frequency transmitter/receiver and antenna for adjusting the status of the electrical device in response to control information in a radio frequency signal. The transmitter/receiver receives the radio frequency signal via the antenna and transmits a status radio frequency signal with information regarding the status of the electrical device. A master control unit has at least one actuator and status indicator and a transmitter/receiver for transmitting a radio frequency signal having the control information therein to control the status of the electrical device and for receiving the status information from the control device. The status indicator indicates the status of the electrical device in response to the status information. A repeater receives the radio frequency signal from the master unit and transmits the control information to the control device and receives the status information from the control device and transmits it to the master unit.
