to_lighter Posted January 9, 2009 Share Posted January 9, 2009 Hi gang, Here is a tough one. After sundown I would like to slowly fade down any light that is on to 75% brightness. I could do this by creating a bunch of scenes, each with one light in it, and a bunch of programs that check the time and control these scenes. However, that would be a tremendous amount of work, and is only practical for a small number of lights. Is there a way to send a message at sundown to any light that is on to slowly fade down? Cheers! Link to comment
Sub-Routine Posted January 9, 2009 Share Posted January 9, 2009 Tough and also Odd. Why would you dim the lights at sundown? I agree it would take some time to write a program for each device, although Copy Program can speed that up. It's going to take Scenes to use long ramp rates for slow dims. Fades happen quickly. You could make several scenes with several lights in each scene and set new levels for each device in the scene. Use Sundown +/- to stagger the programs by a minute or two. I don't know why you have the 75% criteria. , but I do have a program where, at a sundown offset, if a specific light is below a certain level I activate a scene to brighten the room (Welcome Home). If that one light is above the test level I assume someone is already using the room and no changes occur. Rand Link to comment

After dark, it is unnecessarily bright in the room if the lights are at 100%. Fading to 75% seems to be a more appropriate level. The difficulty with using scenes with multiple lights for this task is that if the light were not already on, it would fade up to 75%, which is not really what I was looking for. Cheers!

Steve Sullivan Posted January 9, 2009 Share Posted January 9, 2009 I suppose you can make a program for each light you want to adjust that checks it's status. If light A is >XX% Then use that status program either in the folder to allow it to run, or as part of the fade program's IF. Link to comment
Sub-Routine Posted January 9, 2009 Share Posted January 9, 2009 If you are already controlling the lights in groups (scenes) can't you check the level of one light in each scene? Otherwise I'm afraid it's check each light's status. I would suggest breaking that down into groups of programs with different times on the folders. Rand Link to comment
