Method and device for controlling the execution of at least one action of an object connected in a communication network

A system for controlling the execution of at least one action by a connected building object in a communication network, the system comprising:

• a remote controller adapted to connect to said communication network and to command the execution of said at least one action by the connected building object;
• and
• the connected building object;
• wherein the connected building object comprises:
• a network interface allowing connection to said communication network;
• a processor adapted to execute said at least one action of the connected building object, and comprising at least:
• an opening module that opens a secure connection between said connected building object and the remote controller by implementing a first security certificate of the connected building object and a second security certificate from the remote controller, wherein the opening of the secure connection allows encrypted communication between said connected building object and the remote controller, and further comprising reception of the second security certificate from the remote controller;
• a receiving module that receives, via said secure connection, a command to execute said at least one action issued by said remote controller, according to a communication protocol;
• a module for extracting a value from a predetermined field of the remote controller's second security certificate, referred to as the remote controller's access authorisation value;
• a module for checking, in a storage structure for storing associations between access authorization values and sets of authorized commands, that said received command belongs to a set of at least one authorized command associated with said access authorisation value, the storage structure being stored in an electronic memory of said connected building object;
• and
• a module for executing, when the check is positive, said at least one action associated with the received command.
