WLED Integration, supported_color_modes doesn't include color_temp or rgbw

[harrismck]

The problem

I have an LED strip controlled by WLED that supports color temperature. I can set the color temperature via HomeAssistant actions, but the light entity shows up in HA with only "rgb" in the supported_color_modes.

For a while, I used this fork of the WLED integration to work around the issue, but the fork introduced some other problems. I thought an update to the official WLED integration fixed this, but it definitely seems broken now.

The main downside is that UI controls (cards, etc) don't have the UI to set color temp.

Are you sure you have rgbw leds? WLED's UI fakes out color temp with RGB led's where HA does not. I have a mix of both and rgbw wled entities do support color_temp.

Ah, right you are! I was fooled by WLED's UI, my actual rgbw leds do support it in HA.
The action with color_temp_kelvin still works for all of them though so I guess this is less of a bug and more of a feature request. If it is possible to set the color of a light in that way... I'd like to be able to do so in the UI!
