Ramp DOWN light?

I use Fibaro FGD211 for my light controller. I see there are a few plugins for a light to ramp up that are a few years old. But nowhere do I find anything on ramping down a light. Very strange.

Has anyone acheived this as yet? (Vera 3 UI5)

I need theator lights to dim slowly as a scene runs. I cannot set a variable inside the Fibaro as this results in a permanent ramp change. I need a plugin or trick to do this.

Any ideas???

There is an example of slow dimming using Lua code here.

You can change the dim step and time interval to suit your requirements.
