Looks like a smart alarm on my VA6 works as a simple standard alarm. It buzz always at time that was set. Instead of buzzing in range of 30 min before the time that was set - depending of sleep stages. In my VA6 it never happens this way. The buzz is always at 06:20 neverless sleep stages, sleep conditions. Moreover, if i wake up (without alarm) 10-15 min before its time - it will buzz only at 6:20. Right like a simple standard alarm.
