Motion Lighting & Group Scenes app ... not working

Hi.

I created a scene using Groups and Scenes app followed by setting up a trigger event using the Motion Lighting app to fire the a scene.

For some reason, the scene isn't triggering.

I made a short screencast to help clarify the issue. link

Any ideas?

::update:: Scene seems to be firing now. Maybe it takes time to "think" about it? ha...
