Abstract:
1. A method for reprogramming a plurality of bidirectional objects belonging to a home automation installation, each object of the home automation installation having a univalent identifier stored in a memory, wherein the method comprises: i. providing an initial common key; ii. storing the initial common key in the memory of at least a first object, a second object, and a third object of a group of objects in the home automation installation; iii. pairing the first object to the second object and to the third object, wherein the pairing of two objects includes storing in the memory of the objects to be paired information on the identifier of the other object; iv. providing a new common key, the provision of the new common key being launched by a user, and storing the new common key in the memory of the first object and in the memory of the second object, excluding the third object from being provided with the new common key; then v. invalidating the pairing between the first object and the second object and between the first object and the third object, but keeping in the memory of the second and the third object the information on the identifier of the first object and/or keeping in the memory of the first object the information on the identifier of the second object and the identifier of the third object; vi. sending a command from the third object to the first object; vii. receiving a command from the third object at the first object; viii. verifying, in the first object, if the new common key is stored in the memory of the third object; and ix. refusing by the first object the execution of the command sent by the third object, although the first object and the third object are still paired and although the information on the identifier of the third object is stored in the memory of the first object; x. sending a command from the second object to the first object; xii. receiving a command from the second object to the first object; xiii. verifying, in the first object, if the new common key is stored in the memory of the second object; and xiv. when the verification is positive, validating the pairing between the first object and the second object and executing by the first object the command send by the second object, thereby providing for the third object to be excluded from the group without reprogramming the pairings existing between the objects of the home automation installation.
