Abstract: Monitoring and controlling modules of a system includes obtaining, with a portable piece of equipment associated with an installation operator, an identifier that encodes a physical network address of a communicating module, and obtaining, with the portable piece of equipment, an installation geolocation information item. The physical network address and the installation geolocation are transmitted to a central server by the portable piece of equipment, and the central server verifies prior storage of said physical network address. If the physical network address cannot be verified, the server stores the physical network address in association with the identifier.

Abstract: A method and device for secure configuration and use of a system of modules for monitoring and/or controlling pieces of domestic, industrial or office equipment, the system including a communicating module, able to receive items of monitoring and control information from other modules of the system and to communicate the information items received to a central server via a first communication mode. The configuration method includes obtaining, with a portable piece of equipment associated with an installation operator, an identifier able to encode information items containing a physical network address of the communicating module, and obtaining an installation geolocation information item, and transmitting to the central server an information item containing the physical network address and the installation geolocation information item. A configuration authorisation is granted depending on a verification of prior memorisation of said physical network address in a memory of the central server.
