A method for configuring at least one home automation installation of a building , the home automation installation comprising a plurality of home automation devices (D), the method being executed by a management unit (Sv) connected to the at least one home automation installation and comprising the following steps: i. Reception (ECfES1) of a configuration message (MCf) emitted from a central control unit (U) of a home automation installation or a user terminal (T), the message (Mcf) containing an indication on a commissioning, a configuration or a reconfiguration of a home automation device (D); ii. Determination of at least one low-level device model class or type (RDT) corresponding to the home automation device (D), each home automation device (D) being represented by at least one generic device model instance (GD) and at least one low-level device model instance (RD); iii. Creation (ECfES2) of at least one low-level device model instance (RD) according to the low-level device class or type (RDT) defined at step ii and corresponding to the home automation device (D); iv. Determination (ECfS3) of a model conversion (CvM) converting a low-level device type or class (RDT) into at least one generic device model class or type (GDT) on the basis of a model conversion rule (MCR) selected according to the low-level device model instance (RD) determined at step iii or its type (RDT); v. Creation (ECfES4) of at least one generic device model instance (GD) for the at least one low-level device model instance (RD) on the basis of the at least one type or class (GDT) corresponding to the model conversion (CvM) determined at step iv; vi. Saving of the at least one generic device model instance (GD) in an associated manner with the at least one low-level device model instance (RD); Wherein the generic device model defines: - A set of commands or functions associated to said model and/or - A set of statuses or status variables associated to said model and/or - A set of attributes associated to said model. i. Reception (ECfES1) of a configuration message (MCf) emitted from a central control unit (U) of a home automation installation or a user terminal (T), the message (Mcf) containing an indication on a commissioning, a configuration or a reconfiguration of a home automation device (D); ii. Determination of at least one low-level device model class or type (RDT) corresponding to the home automation device (D), each home automation device (D) being represented by at least one generic device model instance (GD) and at least one low-level device model instance (RD); iii. Creation (ECfES2) of at least one low-level device model instance (RD) according to the low-level device class or type (RDT) defined at step ii and corresponding to the home automation device (D); iv. Determination (ECfS3) of a model conversion (CvM) converting a low-level device type or class (RDT) into at least one generic device model class or type (GDT) on the basis of a model conversion rule (MCR) selected according to the low-level device model instance (RD) determined at step iii or its type (RDT); v. Creation (ECfES4) of at least one generic device model instance (GD) for the at least one low-level device model instance (RD) on the basis of the at least one type or class (GDT) corresponding to the model conversion (CvM) determined at step iv; vi. Saving of the at least one generic device model instance (GD) in an associated manner with the at least one low-level device model instance (RD); - A set of commands or functions associated to said model and/or - A set of statuses or status variables associated to said model and/or - A set of attributes associated to said model. <EOS>
