Abstract: A communication method for a home automation actuator comprising an electric motor driving a moving element in a building and two electric terminals making it possible to power the actuator by a power supply and communication entity (IMS) and allowing communication between the actuator and the power supply and communication entity (IMS), the method comprising the following steps: analysis of a power supply signal supplied by the power supply and communication entity; generation of a first time-sequence of a response signal, representative of a first predetermined calibration information element, called first calibration sequence; sending of a series of time-sequences of the response signal, representative of a series of information elements, each information element of this series, equal to the calibration information element, being represented by a time-sequence which is an image of the first calibration sequence.

Abstract: Method of operating a power supply and communication entity intended to form part of a system with at least one home-automation actuator comprising an electric motor for driving a movable element in a building, the power supply and communication entity comprising two electrical terminals for linking to the actuator, making it possible to power the actuator and allowing communication between the actuator and the power supply and communication entity, the method comprising two mutually exclusive modes of operation, a command execution mode and a communication mode, to each mode of operation there corresponding a specific power supply signal, the method comprising the steps: —choice of a mode of operation; —generation between the terminals of a power supply signal specific to the mode of operation chosen.
