Abstract:
1. A method for implementing a radio-electrical command transmitted in a single radio-electrical signal, the command being for the control of a home automation device where the command includes at least one of an instruction to move a movable element of the home automation device and a learning-mode instruction of the home automation device, the radio-electrical command being generated by the action of a user on a remote control, the method comprising: a command receiver receiving the radio-electrical signal directly from the remote control; measuring at least a first electromagnetic characteristic and a second electromagnetic characteristic of the single radio-electrical signal received directly from the remote control; comparing the first characteristic to the second characteristic to determine whether a transmission zone of the remote control is a near-field zone or a far-field zone, wherein comparing the first characteristic to the second characteristic includes at least one of calculating a ratio based on the first and second characteristics and calculating a difference based on the first and second characteristics; and controlling the movable element as a function of the received command and as a function of the transmission zone of the remote control, wherein, at least in one operating mode, a transmission of commands is validated only when the remote control is in the near-field zone, the near field zone is a zone substantially immediately proximate to the command receiver.
