A system for controlling electrically-operated devices within an area such as a room is disclosed. The system comprises a visual display screen upon which is displayed a representation of the area within which electrically-operated devices are disposed, and one or more representation of an electrically-operated device within the area. An input device is operable by a user to activate a representation of an electrically-operated device. In response, a control stage operates in response to inputs received from the input device, to modify the operation of the electrically-operated device associated with the representation. The electrically-operated devices to be controlled by the system may include, but are not limited to: electrical devices, such as a fan, a heater, a light, air conditioning; effectors for opening and closing a door or a window; electronic devices such a television set, a television receiver/decoder, a video recording device and audio equipment. The system can operate in a design mode, in which a user can create or amend the representation of the area and the electrically-operated devices within it.
