Have read limited info on the value of adjusting light temperatures throughout the day. And, I think I understand your use case for building this app and how it has evolved over time with much input from others.
But, though I remember others mentioning needs/features that sounded applicable to my use case, I'm not 100% positive that I can do what I think I want to do...
The 'Advanced Brightness Options' menu is where I have spent most of my time as I want to control CT by mode (Early, Morning, Active Day, Evening, Relax & Sleep). In my residential application, many lights are not active during the day. But, for the ones that do happen to be turned on, I want those lights to follow color temperature rules by mode. And, since I do not currently have motion activation in most rooms yet, I'm not interested in setting a brightness level by mode. That will be handled by the Button Controller setup for the applicable Pico(s).
So, in the ABO menu, I'm leaving Brightness for each mode blank and entering the actual CT I want if a light happens to be turned on. When the mode changes, the CT for ALL configured bulbs should change without increasing bulb brightness above 0 for the currently OFF bulbs nor from current brightness setting for currently ON bulbs. That's what I'm assuming is possible with your app.
It seems like your core use case for app development was to, essentially, leave certain or all lights on throughout an occupied period of the day and have the app cycle through CT's automatically set by the app which is based on the arc of the sun via Zip Code.
Is my Use Case possible with your app or might I be better off with a simple Custom Action to set colorTemp by mode?
