Beddit sleep tracker marginaly detects my sleepwalking

Beddit sleep tracker provides a 2 stages sleep graph with only light and deep sleep (see graph below) but no sleep interruptions defined.

Nonetheless I used the "baseline" phases of my sleep as equivalent of a sleep interruptions, to see if that correlates with the complexity levels of my sleepwalking.

As the graph below shows at most Beddit sees my sleepwalking 40% of the time (for level 5 events).
So as for B1 and UP, not a useful tool to monitor my sleepwalking.
