Grouping multiple events

I have lights that are triggered by a motion sensor to turn On for 30 minutes.

The problem is that sometimes (5% of the time or so), when the lights turn OFF, it activates the motion sensor again thus restarting the cycle.

In other words:

1. Lights go off
2. Motion sensor triggered
3. Lights go back on

Using the join-wait node, I can now look for this specific sequence to happen within a 12 second window - and if so - turn the lights back off. (Note: join-wait can be chained for more complicated event sequences/groups as well).
