Using Hue Bulbs in sitemap/panel (2010 lights)?

Hello all:

I’m trying to set up my HabPanel currently. I’ve got Hue A19 Gen 3 bulbs which support whites and colors. I can’t seem to figure out how to dim the bulbs using the sitemap or Habpanel view. The binding shows 4 channels:

  1. Color (Color)
  2. Color Temperature (Dimmer)
  3. Alert (String)
  4. Color Loop (Switch)

How do I set up a dimmer to adjust the brightness? Connecting to the color temp dimmer, as expected, changes the color temperature.

The paperUI has separate slide bars for Color, Brightness and Saturation. Below is an example of the events.log output when I adjust brightness on the paperui control:

2018-02-16 16:26:59.692 [vent.ItemStateChangedEvent] - LivingRoomOverheadB_Color changed from 40,85,87 to 40,85,100

So it looks like it has color listed as something similar to I think a CIE type system. Is there a way to create a specific dimmer that only adjusts the brightness?

Thank you!
