Add units and improve descriptions

* Add min-max to descriptions when not covered by min/max values.
* Add units

NOTE: per style guide, 0-99 should not be accepted as percent, however, in this particular case (except Dimmer Level), percent is percent humidity, and values are absolute and not a relative range, thus I added % as units.
