I am not sure how many of you use Milight LEDs or are interested in buying some. For sure, IWY Master and WIFI370 provide the better technical solution, but Milight has a much lower price tag. One of the downsides of Milight is the limited color control. It only provides 255 presets for hue, 19 presets for brightness, and absolutely no saturation control.
The intent is to support Milight as part of pimatic-led-light which currently provides a RGB color picker. See also http://forum.pimatic.org/topic/332/plugin-for-wifi-controlled-led-light-iwy-light
I have implemented a Milight adapter for the RGB color picker on a dev-branch, but the user experience is pretty average imho. Therefore, this is to suggest an alternative UI adapter (as part of pimatic-led-light) for Milight devices. The UI shall simply consist of a brightness slider (DimmerDevice with value 0 used for Off) and a Milight-specific Color Slider with 256 values, where 0…255 is used for the color presets and 256 for white mode. To give you a better idea of it I have drafted a prototype of the color slider - see https://jsfiddle.net/WittigMarcus/p0xw0jks/
Note, the Milight color wheel is completely different from the HSV color circle! See image below. This feature request is to get your feedback and to get an idea how many potential Milight users we have on board
