4.1.3 Driveway lighting
A motion detector activates the dimmer via the soft switching object.
The lighting is dimmed up within 5 seconds if a movement is detected.
This delay gives the eyes enough time to adjust to the light without being dazzled
The lighting is gradually dimmed down within a minute and then switched off after the configured
time has elapsed or a Soft OFF telegram is received via the button or via the motion detector (cyclic).
