A method for communicating within a dynamic communication network between a plurality of products of a same building or of a same group of buildings, characterized in that each product comprising at least one radio module, a processing processor, the radio module being configured to transmit and receive radio data including at least one identifier data and at least one data on the quality of the radio signal, the radio module being configured to transmit and receive said radio data only within a reception perimeter, the method comprising at least one step of establishing the dynamic communication network between the plurality of products, the step of establishing the communication network being performed automatically and comprising the following sub-steps: (a) each radio module of each product of the plurality of products transmits radio data, (b) the radio module of a first product detects radio data transmitted in step (a) in the reception perimeter of the first product and receives them, (c) the processing processor of the first product analyzes the radio data received in step (b), characterized in that it comprises the following sub-steps: (d) the processing processor of the first product selects a product among the plurality of transmitting products whose radio data transmitted in step (a) has been received by the first product in step (b), the selected product being selected on the basis of the analysis of the signal quality data carried out in step (c), said selected product being considered as the most remote product, that is to say the product whose signal reception quality is the lowest compared to all the signal quality data received in step (b) by the first product, (e) the radio module of the first product transmits to the most remote product selected in step (d) the identifier data resulting from the radio data received in step (b), (f) in response, the radio module of the most remote product sends to the first product identifier data originating from radio data which it has itself detected and received within its reception perimeter from the plurality of products, (g) the radio module of the first product receives radio data sent in step (f), (h) establishment of the communication network between all building products or the group of buildings. (a) each radio module of each product of the plurality of products transmits radio data, (b) the radio module of a first product detects radio data transmitted in step (a) in the reception perimeter of the first product and receives them, (c) the processing processor of the first product analyzes the radio data received in step (b), (d) the processing processor of the first product selects a product among the plurality of transmitting products whose radio data transmitted in step (a) has been received by the first product in step (b), the selected product being selected on the basis of the analysis of the signal quality data carried out in step (c), said selected product being considered as the most remote product, that is to say the product whose signal reception quality is the lowest compared to all the signal quality data received in step (b) by the first product, (e) the radio module of the first product transmits to the most remote product selected in step (d) the identifier data resulting from the radio data received in step (b), (f) in response, the radio module of the most remote product sends to the first product identifier data originating from radio data which it has itself detected and received within its reception perimeter from the plurality of products, (g) the radio module of the first product receives radio data sent in step (f), (h) establishment of the communication network between all building products or the group of buildings.
