 *
 *  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
