OK, I took a quick look at the original Groovy DTH for the dimmer, written by the always impressive @krlaframboise , and while I am limited in my understanding because I use a screen reader, it looks like that was created with a whole bunch of child devices which handled the setting of the individual colors and blink rates for the indicator LEDs.
The original edge Driver architecture didn’t use a parent/child construct but they did add one later because they couldn’t get voice control of the individual components without it.
So my guess is you could use exactly the same approach in an edge driver and build on the work that @krlaframboise did for the groovy version as long as there’s not some new limit on the number of child devices.
So I would suggest going to the author of the new edge driver and making that suggestion to them.
Here’s the link to the Groovy DTH for the dimmer so you can see what I mean
Once you have those child devices, turning them on and off from a regular routine should be very straightforward. They’ll just look like another RGBW smart bulb.
