The invention concerns a method for discovering the configuration of a home-automation facility, the home-automation facility comprising a plurality of home-automation devices and a plurality of central control units (U1, U2); the method being executed by a management unit (Sv) or by a mobile terminal (T) connected to the at least one home-automation facility and comprising the following steps: receiving (EDCfT3) a first message (MSScn1) originating from a first control unit (U1) of the plurality of central control units (U, U1, U2), the first message comprising a first piece of signalling information concerning at least one first sub-scenario (SScn11) prerecorded in said first central control unit linked with a scenario identifier (ScnID), the first sub-scenario (SScn1) comprising at least one first control intended for the at least one device attached to said first central control unit (U1); receiving (EDCfT4) a second message (MSScn2) originating from a second control unit (U2) of the plurality of central control units (U1, U2), the second message comprising a second piece of signalling information concerning at least one second sub-scenario (SScn2) prerecorded in said second central control unit (U2) linked with the scenario identifier (ScnID), the second sub-scenario (SScn2) comprising at least one second control intended for the at least one device attached to said second central control unit (U2); reconstituting (EDCfT5) a scenario (Scn) associated with the scenario identifier (ScnID) comprising at least the at least one first control and the at least one second control, by combining the first sub-scenario (SScn1) and the second sub-scenario (SScn2).
