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.
