FYI: Milight has released a new version of its bridge controller and new RGBWW/CW bulbs which provide support for full colour mode and white mode with adjustable colour temperature. The bulbs use quality LEDs from Samsung.Another big plus is the new version 6 protocol is bidirectional and provides error detections! So, the new version 6 is getting much closer to the features other (more expensive) lightning systems provide
Unfortunately, the new protocol is rather complex and it will take some time to support it as part of Pimatic. I have just received the new bridge controller and started experimenting with it.
