Device and a system for control and/or command

A system for commanding and/or controlling at least one element for visual or thermal comfort or for security of a building, comprising:

• at least one element for visual or thermal comfort or for security, in particular an actuator of a movable equipment of the building, a sensor for measuring a physical quantity or any other element related to the visual or thermal comfort or to the security of the building,
• a central entity arranged so as to command and/or control the at least one element for visual or thermal comfort or for security,
• a device for commanding and/or controlling an element for visual or thermal comfort or for security of the building, arranged so as to receive data, according to a wireless communication protocol, from a complementary communication module of the central entity, the device comprising:
• a display screen, and
• an electronic control unit provided with a communication module arranged so as to receive data, according to the wireless communication protocol, from the complementary communication module of the central entity arranged so as to command and/or control the at least one element for visual or thermal comfort or for security, said central entity being arranged so as to provide and emit towards the electronic control unit representative data related to the visual or thermal comfort, to the electrical consumption or to the security of the building, and
• the electronic control unit being configured to generate a display configuration based on at least one content datum and on at least one display descriptive datum defining the arrangement of a display of the at least one content datum, the at least one content datum and the at least one display descriptive datum being comprised in the representative data related to the visual or thermal comfort, to the electrical consumption or to the security of the building received via the communication module, the display screen being configured to display said display configuration,
• wherein the at least one display descriptive datum defines a division of the display configuration into areas and the at least one content datum to be displayed in each of said areas,
• wherein the at least one display descriptive datum defines a representation format of the at least one content datum in the form of a numerical display, of an icon to be selected in a predefined list, or of a graph,
• wherein the electronic control unit is configured to present a first operating mode, during which an update of the representative data is carried out according to a first refresh rate, and a second operating mode, during which an update of the representative data is carried out according to a second refresh rate higher than the first refresh rate.

A method for commanding and/or controlling at least one element for visual or thermal comfort or for security of a building, the method including the following steps:

• emitting representative data related to the thermal or visual comfort of the building from a central entity arranged so as to command and/or control at least one element for visual or thermal comfort or for security according to a wireless communication protocol, the representative data comprising at least one content datum and at least one display descriptive datum defining the arrangement of a display of the at least one content datum,
• wherein the at least one display descriptive datum defines a division of a display configuration into areas and the at least one content datum to be displayed in each of said areas,
• wherein the at least one display descriptive datum defines a representation format of the at least one content datum in the form of a numerical display, of an icon to be selected in a predefined list, or of a graph,
• receiving, via a communication module of a command and/or control device, the representative data emitted by the central entity, and generating the display configuration based on the at least one content datum and the at least one display descriptive datum comprised in the representative data (DR), and
• displaying said display configuration on a screen of the command and/or control device,
• wherein the control device is configured to present a first operating mode, during which an update of the representative data is carried out according to a first refresh rate, and a second operating mode, during which an update of the representative data is carried out according to a second refresh rate higher than the first refresh rate.
