 *
 *  Aeon Home Energy Meter v2 (US)
 *
 *  Author: Barry A. Burke
 *  Contributors: Brock Haymond: UI updates
 *
 *  Genesys: Based off of Aeon Smart Meter Code sample provided by SmartThings (2013-05-30). Built on US model
 *			 may also work on international versions (currently reports total values only)
 *
 *  History:
 * 		
 *	2014-06-13: Massive OverHaul
 *				- Fixed Configuration (original had byte order of bitstrings backwards
 *				- Increased reporting frequency to 10s - note that values won't report unless they change
 *				  (they will also report if they exceed limits defined in the settings - currently just using
 *				  the defaults).
 *				- Added support for Volts & Amps monitoring (was only Power and Energy)
 *				- Added flexible tile display. Currently only used to show High and Low values since last
 *				  reset (with time stamps). 
 *				- All tiles are attributes, so that their values are preserved when you're not 'watching' the
 *				  meter display
 *				- Values are formatted to Strings in zwaveEvent parser so that we don't lose decimal values 
 *				  in the tile label display conversion
 *				- Updated fingerprint to match Aeon Home Energy Monitor v2 deviceId & clusters
 *				- Added colors for Watts and Amps display
 * 				- Changed time format to 24 hour
 *	2014-06-17: Tile Tweaks
 *				- Reworked "decorations:" - current values are no longer "flat"
 *				- Added colors to current Watts (0-18000) & Amps (0-150)
 *				- Changed all colors to use same blue-green-orange-red as standard ST temperature guages
 *	2014-06-18: Cost calculations
 *				- Added $/kWh preference
 *	2014-09-07:	Bug fix & Cleanup
 *				- Fixed "Unexpected Error" on Refresh tile - (added Refresh Capability)
 *				- Cleaned up low values - reset to ridiculously high value instead of null
 *				- Added poll() command/capability (just does a refresh)
 * 	2014-09-19: GUI Tweaks, HEM v1 alterations (from Brock Haymond)
 *				- Reworked all tiles for look, color, text formatting, & readability
 *	2014-09-20: Added HEMv1 Battery reporting (from Brock Haymond)
 *	2014-11-06: Added alternate display of L2 and L2 values instead of Low/High, based on version by Jayant Jhamb
 *  2014-11-11: Massive overhaul completed (see GitHub comments for specifics)
 * 				-
