The present invention concerns a method for controlling a home-automation facility comprising at least one central control unit (U1, U2) belonging to a home-automation facility; the method being executed by a user terminal (T) and comprising the following steps: selecting (ECTLT1) a first local connection mode (CM1) or a second wide area network connection mode; establishing (ECTLT2) a connection between the user terminal and at least one target unit (U1, U2, Sv), said at least one target unit (U1, U2, Sv) being a central control unit (U1, U2) in the case in which the first local connection mode (CM1) has been selected, and a management unit (Sv) in the case in which the second wide area network connection mode has been selected; sending (ECTLT3) a discovery message (MCTLD1, MCTLD2, MCTLD′) linked with a facility identifier (StID) to at least one target unit (U1, U2, Sv); receiving (ECTLT5, ECTLT7) at least one topology description message originating from the target unit (U1, U2, Sv) comprising a description of a group of devices (DGrSt) attached to the facility identifier (StID).
