Basically, there are two ways to activate scenes (when you push a scene button):
Basic Scenes
ThinkEssentials says:
* Bedroom lamp, go to 50%
* Bedroom overhead, go to 80%
* Hallway lights, go to 0%
Advanced Scenes
ThinkEssentials says:
* Bedroom lamp, bedroom overhead, and hallway lights: all of you activate "scene 1" simultaneously
In the advanced scenario, any of the devices in direct range of the PC will go to their target levels simultaneously; in the basic scenario they do it in rapid succession--which creates a bit of a "popcorn effect." (as in pop, pop, pop).
