LimitlessLED not able to switch to warm white / cold white while an RGB color is active

Make sure you are running the latest version of Home Assistant before reporting an issue.

You should only file an issue if you found a bug. Feature and enhancement requests should go in the Feature Requests section of our community forum:

Home Assistant release (hass --version): 0.49.0

Python release (python3 --version): Python 3.4.2

Component/platform: limitlessled

Description of problem: When trying to switch from any color back to cold white/warm white, nothing happens, whether by dragging the color temperature slider or calling light.turn_on with color_temp/kelvin parameter. The bulb has to first be switched back to "white mode" by setting an RGB white.

Expected: The bulb should switch to white mode automatically when it is currently in RGB color mode.

Problem-relevant configuration.yaml entries and steps to reproduce:

light:
  - platform: limitlessled
    bridges:
      - host: 10.47.173.144
        groups:
        - number: 1
          type: rgbww
          name: Decke
        - number: 2
          type: rgbww
          name: Couch
        - number: 3
          type: rgbww
          name: Schreibtisch
        - number: 4
          type: rgbww
          name: Tisch
        - number: 1

1. Set bulb to any RGB color
2. Try to switch to a warm white/cold white

I opened without realizing a duplicate: https://github.com/home-assistant/home-assistant/issues/9107. There is some extra information to be found.

@PheiPheiPhei

One quick fix that i found it's to insert in ˜/homeassistant/components/light/limitlessled.py after line 350 the following: self._color = WHITE (check the indent to be the same as line 350). This has the following effect: As soon as you set the color_temp to a valid value, the color will default to white:

light.living_room_table_light:
  state: on
  brightness: 255
  #color_name: white -> not needed anymore / has to be removed
  color_temp: 154

@happyleavesaoc - FYI

I don't have an rgbww bulb to test this fix with. I could see if it has adverse effects on the v5 bridge though.

[andrei-radulescu]

this should only affect rgbww - but the transition is not smooth when changing from a RGB color like before 0.49. There where some fundamental changes in that release that don't agree much with v6 - especially with transitions.

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates.

Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment :+1:

@balloob Nope :) a new release won't fix this. A suggestion for the fix can be found in the upper comment.
