摘要

The invention relates to a home automation method for monitoring at least one opening (21) monitored relative to a frame (22). At least one transmitter (24) is fixed to a first element selected from the frame and a monitored opening, the transmitter being adapted to emit radiation, selected from electromagnetic radiation and acoustic radiation, in the direction of at least one portion at least one second element distinct from said first element and selected from the frame and a monitored opening. At least one receiver (26) is selected and arranged to capture reflected radiation emanating from at least one emitter and reflected by at least one second element, and to provide reflection signals representative of at least one characteristic of said reflected radiation.
