Le dispositif de gestion (100) comprend : une première unité d'interface (110) pour communiquer avec l'instrument d'installation ; une seconde unité d'interface (12) pour communiquer avec l'autre dispositif de gestion ; et une troisième unité d'interface (13) pour communiquer avec au moins deux types de dispositifs par l'intermédiaire d'un protocole pré-régulé. Lorsque le dispositif de relais est connecté à la troisième unité d'interface (13), le dispositif de gestion (100) transmet, de la troisième unité d'interface (13) à un serveur par l'intermédiaire du dispositif de relais, des premières informations sur l'instrument d'installation, qui sont reçues par l'intermédiaire de la première unité d'interface (11), et des secondes informations qui concernent un autre instrument d'installation géré par l'autre dispositif de gestion et sont reçues par l'intermédiaire de la seconde unité d'interface.
