      I am not sure what you mean. As I understood the blink feature, it
      warns the occupants of a room that lights will go out soon, when the
      Present_Value was written to a value of zero.

      The auto-off feature on the other hand would lead to a relinquish of
      the Present_Value if the value was NOT zero. This is heavily used in
      Europe for staircase lighting applications, where lights shall go out
      some time after they were switched on by someone (e.g. by pressing a
      light switch when entering the hallway). Or did I get something wrong

      Best regards,
