SmartThings:Color the Weather
/*
Color the weather
Daniel Root
www.danielroot.info
Should work (but not yet tested with) Phillips Hue devices and any SmartThings device that supports "capability.colorControl".
See https://codebender.cc/sketch:28062 for Arduino code that works with the Arduino SmartShield.
