Light_Level in % or Lux
-
The API states that V_LIGHT_LEVEL should be in %. The example sketch reports in lux. I think Lux should be the way to go (SI) as otherwise it is not clear what the reference is (sunlight? :))

Haha. Yep, the sun is the reference.
Agree, this is a "bug". The problem with the current V_* is that it contains no unit information. A backward compatible solution for this for the 1.5 release would be to introduce a V_LIGHT_LEVEL_LUX. Not pretty but it solves the problem without breaking anything.
2.0 will hopefully solve this without introducing different V_*.
