So, I’ve expanded this after realizing that, in my excitement, I limited myself to only setting color via the Hue/Saturation mode, and not by Color Temperature. So I added another slider with a custom background to match the Color Temp slider in the standard light entity card, along with an input_boolean to determine which input to use.
It works perfectly, except that I could not figure out how to do it all within the Button Card itself, so had to move the logic to a Script and call the Script instead when clicking the Custom button at bottom right.
I also combined my individual Hue lights into this v-stack, and moved it along with my other light stack to its own tab in the UI. The new card looks like this:
I wish we could format number values in standard entity rows on the entity card, so I may try to replace these with Thomas Loven’s Slider Entity Row to gain more control over formatting.
