Abstract

A method of constituting a home automation network comprises bidirectional elements such as actuators (A1, A2, A3), at least unidirectional control elements (C1, C2, C3, S1) and bidirectional control elements (C60, C70, C800). It consists in lastingly functionally linking up at least two elements. The process is characterized in that the lasting functional linkup brings about at least one transfer from a bidirectional element to another bidirectional element of at least one information creating a hierarchical relationship between these two elements.

Claims

1. - A method of constituting a home automation network, comprising bidirectional elements such as actuators (A1, A2, A3), control elements which are at least unidirectional (C1, C2, C3, S1), bidirectional control elements (C60, C70, C800), which consists in lastingly functionally linking up at least two elements, wherein the lasting functional linkup brings about at least one transfer from a bidirectional element to another bidirectional element of at least one information creating a hierarchical relationship between these two elements.

2. - The method of constituting a home automation network, as claimed in claim 1, wherein the information creating a hierarchical relationship between these two elements comprises a group name (NG1;

Ng2).

3. - The method of constituting a home automation network, as claimed in claim 2, wherein the transmission of the group name (NG1;

NG2) is coded according to an encryption algorithm.

4. - The method of constituting a home automation network, as claimed in claim 1, wherein the information creating a hierarchical relationship between these two elements comprises the identity of the links already established with the element sending the information.

5. - The method of constituting a home automation network, as claimed in claim 1, wherein the lasting functional linkup between two bidirectional elements is achieved under the supervision of a third element which is itself previously authenticated at one of the elements during a learning operation.

6. - The method of constituting a home automation network, as claimed in claim 1, wherein the functional linking up of a bidirectional control element (C60) with a bidirectional element (A1, A2, A3) is performed under the supervision of an at least unidirectional control element (C1, C2, C3).

7. - The method of constituting a home automation network, as claimed in claim 1, wherein the functional linking up of an at least unidirectional control element (C1, C2, C3, S1) with a bidirectional element (A1, A2, A3) is performed under the supervision of a bidirectional control element (C60).

8. - The method of constituting a home automation network, as claimed in claim 1, wherein the functional linking up of two bidirectional control elements (C60, C70) of the same hierarchical level is ensured by the linking up of each of the bidirectional control elements with a control element of higher hierarchical level (C800).

9. - The method of constituting a home automation network, as claimed in claim 1, wherein the functional linking up of two bidirectional elements (A1, A2, A3) is ensured by the successive functional linking up of each of them with one and the same bidirectional control element (C60).

10. - The method of constituting a home automation network, as claimed in claim 1, wherein, during a functional linking up of a bidirectional control element (C60, C70 or C800) with another element, the latter communicates to said bidirectional control element the set of identifiers relating to the elements, with which it is already linked up.

11. - The method of constituting a home automation network, as claimed in claim 1, wherein, during a functional linking up between two control elements of different hierarchical level, the transmission of information regarding the preestablished relationships takes place from the element of lower level to the element of higher level.

12. - The method of constituting a home automation network, as claimed in claim 1, wherein, during a functional linking up of a bidirectional control element (C60, C70, or C800) with another element, there is exchanged a group name NG becoming common to all the elements of lower level, linked up with said bidirectional control element.

13. - The method of constituting a home automation network, as claimed in claim 12, wherein the transmission of the group name (NG1;

NG2) is coded according to an encryption algorithm.

14. - A network to which the method claimed in claim 1 applies.
