Abstract

L'invention concerne un procédé de surveillance de l'état d'une batterie (1) d'un dispositif de communication radio (2), en particulier d'un détecteur radio et/ou d'un actionneur radio. Selon l'invention, un message est produit par le dispositif de communication radio (2) et reçu par radio, le message étant reçu par un dispositif de contrôle (3) ; après la réception du message, la valeur d'un compteur (4) associé au dispositif de communication radio (2) et appartenant au dispositif de commande (3) est augmenté d'une valeur pouvant être prédéterminée, et, lorsque la valeur du compteur excède une valeur limite pouvant être prédéterminée, une signalisation de surveillance de batterie associée au dispositif de communication radio (2) est produite et émise, au moins indirectement.
