* Required: ISY-26 software version 2.6.2 or newer.
*
* Version 3.3, 10/03/2008: Modified one line to accommodate changes in firmware >= 2.6.7
*
* Version 3.2, 03/02/2008: Added a filter for control and scene names beginning
* with a double-underscore, (like __name) to exclude them from the display.
*
* Version 3.1, 03/02/2008: At the suggestion of a reader who has dimmers, changed
* regex to accommodate intermediate "percent" states between on and off,
* translating them all into "On".
