I just checked if this can be done with C4 and it seems it is possible, as below. I am guessing this should also be possible in D3Pro.
Steps:
1) Create a Scene "Room On" with load levels as desired 2) Create a Scene "Room Off" with all loads at 0% 3) Enable the "Room On" scene to be a "toggle scene" and use the "Room Off" scene as the toggle 4) Choose "track all loads" for "Room Off" Scene 5) Choose "Tracking" and "Scene at Final Level" for every load in the "Room Off" Scene
The important steps:
6) Choose "track any load" for "Room On" Scene 7) Choose "Tracking" and "Is On" for every load in the "Room On" Scene
I think the above will work and the Room On/Off button will always work correctly: if all the loads are off it will activate the "Room On" scene, if any off the loads is on it will activate the "Room Off" Scene. Basically the important step is to set the following: if any load is on in the room, it means the "Room On" scene is activated.
I will try this home later and report back. I will also try to check if possible in D3Pro.
I think this is very useful and can be standardized for all projects.
