Transition from white to color fails for RGBW groups. #11

Closed janLo closed 7 years ago

janLo commented 7 years ago

The RGBW group set the target color to None if there is a transition from RGB_WHITE (https://github.com/happyleavesaoc/python-limitlessled/blob/master/limitlessled/group/rgbw.py#L117). It then calls hue_of_color(color) (https://github.com/happyleavesaoc/python-limitlessled/blob/master/limitlessled/group/rgbw.py#L129) which causes a TypeError: 'NoneType' object is not iterable:
