A method of configuring a home automation installation comprising at least one home automation device (D1, D2) and at least one central control unit, the at least one home automation device (D1, D2) being capable of communicating with the central control unit via at least one first local protocol; the method being executed by the at least one central control unit and comprising the following steps: - reception (EcfU3, EcfU4, ECfU2') of at least one configuration message (MCfD1, MCfD2, MCfUsr) relating to a location identifier (P1AD1, P1AD2) of at least one home automation device (D1, D2) according to the first local communication protocol and to at least one definition of a function (P1F1D1, P1F2D1, P1F1D2, P1F2D2) or of a group of functions of the at least one home automation device (D1, D2) according to said first communications protocol; - obtainment (EcfU5) of a location identifier (P2AD1, P2AD2), corresponding to a network address, of the at least one home automation device (D1, D2) according to a second target communication protocol such as the location identifier (P2AD1, P2AD2) is distinct for each home automation device (D1, D2); - recording (ECfU7) of the correspondence between the location identifier (P1AD1, P1AD2) of the at least one home automation device (D1, D2) according to the first communication protocol and the location identifier (P2AD1, P2AD2) of the at least one home automation device (D1, D2) according to the second communication protocol; - recording (EcfU7) of the at least one definition of a function (P1F1D1, P1F2D1, P1F1D2, P1F2D2) or of a group of functions of the at least one home automation device (D1, D2); and/or of a function conversion rule (RCFX) arranged to convert the definition of the at least one function (P1F1D1, P1F2D1, P1F1D2, P1F2D2) or of the function group according to the first communication protocol into at least one definition of a function (P2F1D1, P2F2D1, P2F1D2, P2F2D2) or of a function group according to the second target communication protocol. - reception (EcfU3, EcfU4, ECfU2') of at least one configuration message (MCfD1, MCfD2, MCfUsr) relating to a location identifier (P1AD1, P1AD2) of at least one home automation device (D1, D2) according to the first local communication protocol and to at least one definition of a function (P1F1D1, P1F2D1, P1F1D2, P1F2D2) or of a group of functions of the at least one home automation device (D1, D2) according to said first communications protocol; - obtainment (EcfU5) of a location identifier (P2AD1, P2AD2), corresponding to a network address, of the at least one home automation device (D1, D2) according to a second target communication protocol such as the location identifier (P2AD1, P2AD2) is distinct for each home automation device (D1, D2); - recording (ECfU7) of the correspondence between the location identifier (P1AD1, P1AD2) of the at least one home automation device (D1, D2) according to the first communication protocol and the location identifier (P2AD1, P2AD2) of the at least one home automation device (D1, D2) according to the second communication protocol; - recording (EcfU7) of the at least one definition of a function (P1F1D1, P1F2D1, P1F1D2, P1F2D2) or of a group of functions of the at least one home automation device (D1, D2); and/or of a function conversion rule (RCFX) arranged to convert the definition of the at least one function (P1F1D1, P1F2D1, P1F1D2, P1F2D2) or of the function group according to the first communication protocol into at least one definition of a function (P2F1D1, P2F2D1, P2F1D2, P2F2D2) or of a function group according to the second target communication protocol.
