The invention relates to a system controlling or tracking the operation of household appliances or computer or entertainment equipment (subsequently appliance), comprising an accessory ( 1 ) which is attachable to an operating energy and/or water supply ( 4, 11 ) of the appliance. The accessory includes connections ( 3, 9 ) for sensors monitoring either a user's presence or activity status or an operating environment or wired connections ( 7, 12 ) for signals tracking a flow rate of water or energy consumption, and a processor or a control logic ( 15 ) for processing information received by way of said connections. The accessory monitors the operating status of an appliance connected therewith on the basis of energy claimed thereby (measurement 7 ) or a water flow rate (measurement 12 ) or temperature. In addition, the accessory monitors the signal of an accessory linked functionally with the operating environment of an appliance, such as the signal of a leak ( 18 ), smoke ( 17 ), carbon monoxide, gas or temperature sensor ( 23 ) or other operating status related signal or a user's activity status or presence. The accessory has control outputs for controlling ( 6, 13 ) the operation or operating energy or water of an appliance or the accessory transmits the control signals to local ( 5 ) or remote ( 3 ) communication. |
