You can also track when any one of the loads are at final, on (100%), any level, or off (0%). Not just when all are at final, on or off.
You can only toggle a scene if you have a 2nd scene to be the toggled scene.
A scene is only active or inactice when the tracking conditions have been met.
Keep in mind that an all off scene will appear as active if you are tracking at scene final to be 0% or off. It sounds counter intuitive but all the tracking conditions will have been met and will be active. Test the scene with a nav and flip lights on and off. Watch the behavior or the status in the advanced lighting scene you're testing and compare.
