 *  Version: v1
 *
 *  Updates:
 *  -------
 *  02-27-2016 : Initial commit.  Device handler for an Iris or SmartSense open/close sensor to be used as a doorbell.
 *  03-17-2016 : Due to ST's v2.1.0 app totally hosing up SECONDARY_CONTROL, implemented a workaround to display that info in a separate tile.
