[Example] Radial brightness indicator for dimmable RGB and non-RGB lights

[Tobboss]

Based on the hype of the radial gradient indicator in this reddit post I created a variant for dimmable RGB and non-RGB lights.

It indicates the percental brightness and uses the actual color of the light. For non-RGB lights like my ShellyDimmer2 it uses a fallback color.
This is how I did it in the styling options.

.bubble-icon-container {
  background: radial-gradient(var(--card-background-color) 60%, transparent 0%), 
              conic-gradient(
                rgb(${hass.states['light.test_light'].attributes.rgb_color ? 
                     hass.states['light.test_light'].attributes.rgb_color : '255,255,255'})
                ${hass.states['light.test_light'].attributes.brightness / 255 * 100}% 0%, 
                var(--card-background-color) 0% 100%
              ) !important;
}

I am absolutely no JS expert. If you know a more elegant way to achieve this I am happy to know. For example accessing the actual button / icon color instead of the entities attributes and hard coded fallback values. Also the border of the gradient seems pixelated. Any idea how to smooth it?

Hi, thanks for sharing your variant.

I made a few adjustments:

1. I made the code more flexible by configuring it to read the entity variable directly.
2. I revised the brightness-related section because, for light entities that don't support this feature, the radial indicator wasn't displayed.

 .bubble-icon-container {
        background:
          radial-gradient(var(--card-background-color) 57%, transparent 0%), 
          conic-gradient(
            rgb(${hass.states[entity].attributes.rgb_color ? 
                 hass.states[entity].attributes.rgb_color : '255, 255, 255'})
            ${hass.states[entity].attributes.supported_features !== 0 ?
              hass.states[entity].attributes.brightness / 255 * 100 :
              state === 'on' ? '100' :  '0' }% 0%,
            var(--card-background-color) 0% 100%
          ) !important;
      }

Thank you very much! I absolutely love this enhancement, I am adding it to ALL my light cards! And thank you @Tobboss for the original post!
