Abstract: A power socket fascia arranged to be fitted to a power socket box. The fascia comprises at least one power socket for receiving a plug of an electrical device and including coupling elements for electrically coupling said power socket to a power-line. The fascia includes at least one port for the transmission and/or reception of a signal, in which said at least one port is coupled to a processor electrically coupled to said power-line. The processor is arranged to transfer a signal between said at least one port and said power-line so that said signal can be transmitted to and/or received from said power-line.
