Saxo, this customization worked for me with SAUDIO LED RGB Color Changing Bulbs E26. Instead of overriding the Support_features setting (in my case it was 3) to 63 I used 191 to include SUPPORT_WHITE_VALUES. It added another adjustable control which doesn’t seem to do much for me, but it might for you. In my case, selecting the very center of the color wheel puts it in white mode and the temp adjustment then works. (note: Adjusting the warmth also puts it into the white mode.) Thank you so much for this. How did you find it?
