Abstract

L'invention concerne un procédé (22) pour faire fonctionner un système d'automatisation domestique (10) comportant une unité centrale (12) et une première unité (14) accouplée pour la transmission de signaux au moyen d'une liaison radio (18). Un signal radio (26) est échangé entre la première unité (14) et l'unité centrale (12) au moyen de la liaison radio (18) et une intensité de champ du signal radio (26) est déterminée. L'intensité de champ est comparée à une intensité de champ prévue (34) et en cas d'écart de plus d'une valeur seuil (36) entre l'intensité de champ et l'intensité de champ prévue (34), la présence d'une personne (52) est déduite. L'invention concerne en outre un système d'automatisation domestique (10) et l'utilisation d'une intensité (30) d'un signal radio (26, 40).
