Abstract: Disclosed is a home-automation device including a displacement detector for a monitored object, an accelerometer, an orientation sensor, a memory, a processing unit. The processing unit is programmed to calculate, upon detection of an event, a displacement energy of the detector from the acceleration signals acquired during a waiting time after the triggering event.

Abstract: A home automation device includes a movement detector (20) including an accelerometer and a magnetometer, and a processing unit for processing the signals supplied by the accelerometer and the magnetometer. At least one memory stores a reference orientation of the detector. The processing unit, on detection of a reference event from the acceleration signals, is capable of replacing the reference orientation with the instantaneous orientation of the detector.

Abstract: Disclosed is a home-automation device, a method, a computer program and a home-automation computing unit in which a main home-automation computing unit (30) belonging to a main local network (32) emits a home-automation message to a computer server (35) by a main link (33) and, if there is a fault in the main link (33), re-emits the home-automation message by a translocal link (36, 55), distinct from the main link, directly to a neighbouring computing unit (38, 43) belonging to a neighbouring local network (40, 45) which sends the home-automation message to the computer server (35) by a neighbouring link (37, 46).
