-- Tellstick Switch Handler
-- Created by: Brian Schmidt Pedersen (@briped)
--
-- The device names from the Tellstick MUST be the same as the device names 
--   defined in domoticz, or this script will not work.
--
-- The script is hacked together from several sources, without any knowledge of
--   Lua, so just about everything can probably be done better than my attempt.
--   This also means that no support is given beyond the comments found in this
--   script, and the use of this script is at your own risk.
