A communication method between a collecting unit (5) and a plurality of control devices (7i), each of which is associated with at least an electrical device (1i), via the power line. Messages are exchanged between the collecting unit (5) and the control devices (7i), each of which contains at least: a progressive message number (Pr_N); an addressee identification number (ID_addressee); a portion of information content and/or executable commands (M4). A specific identification number (ID _i) is assigned to each control device and to the collecting unit. The messages are therefore addressable selectively to a specific control device via said addressee identification number.

Des messages sont échangés entre l'unité de collecte (5) et les dispositifs de commande (7i). Chacun desdits messages contient au moins : un numéro d'ordre de message (Pr_N) ; un numéro d'identification de destinataire (ID_destinataire) ; une partie de contenu d'information et/ou de commandes exécutables (M4). Un numéro d'identification spécifique (ID_i) est attribué à chaque dispositif de commande et à l'unité de collecte. Les messages sont donc adressables sélectivement à un dispositif de commande spécifique par l'intermédiaire dudit numéro d'identification de destinataire.
