Abstract
The invention concerns a method and a device for monitoring enablement of an electrical apparatus connected to a power grid. The method consists in: transmitting (A) from a specialised transmitter (ES) to the electrical apparatus (EA) a coded information message comprising an enablement information, in accordance with an enablement control code; and in receiving (B) by means of a receiver (R) equipping the electrical apparatus (EA) said information message. The latter is decoded (C) in accordance with specific enablement data integrated in the receiver (R) to generate decoded enablement data. The enablement of the electrical apparatus (EA) is granted (D, E) if the decoded data are in conformity with the integrated specific enablement data and enablement is refused (D, F) otherwise. The invention is useful for protecting electrical appliances against theft, for managing service delivery on a distant site, monitoring contractual terms.
