I have been using Groups and Scenes for years and what I am seeing with my introduction to CT/RGB lighting is that since I use variables for consistent Color Temperatures that an option in the app not to statically define the Color Temperature or RGB values but read them from a variable and set.
Currently I have a button assigned to each scene for the room and a variable for the color temperature that I set based on time of day. I had to write a separate rule after the scene activates that sets the bulb's CT after it's state changed to On.
The the effect of a rapid color shift is hard on the eyes in the evening when saying that during the last time the bulb came on at 5,000 kelvin from the hard coded scene and you have to shift to 2,700 k via the "on" rule.
Groups and Scenes is no longer receiving active development, having been substantially replaced by Room Lighting. You can import existing Group or Scene apps into Room Lighting to create an identical configuration as a starting point if you don't want to start over (or figure it out on your own), though you'd need to swap the resulting activator devices in any apps they're in use by.
Room Lighting can use variables as values in the activation table, so I think it can do what you're looking for if I understand correctly. But there are a lot of options -- many more than the apps it replaced -- so you can probably figure out something that works for you if that's not it. Good luck!
Thanks for the information. I just imported the easiest scene, office off which is activated by a button push by a groups and scenes activator. That created a Room Lighting activator and brought in the scene which has three devices, Inovelli Blue Switch, Sengled Classic Bulb, and THIRDREALITY RGB bulb.
And guess what the activator actually turned off the lights. Yea that was the easy one. Now I have 4 other scenes where I want to use the variable to control the color temperature when it turn on the RGB bulb. I will let you know if I can get this to work. All my scenes are activated programmatically by a scene activator and that scene activator is managed in Rule Machine as a "Push" the scene activator button.
Found that if you click the color Temperature in the Temp column you can either assign or use the slider for the variable. Just tested and works. It's going to take a bit to rework my automations for the button pushes but thanks again. It is exactly what I was looking for.
