-- Domoticz passes information to scripts through a number of global tables
--
-- otherdevices, otherdevices_lastupdate and otherdevices_svalues are arrays for all devices:
-- otherdevices['yourotherdevicename'] = "On"
-- otherdevices_lastupdate['yourotherdevicename'] = "2015-12-27 14:26:40"
-- otherdevices_svalues['yourotherthermometer'] = string of svalues
--
-- uservariables and uservariables_lastupdate are arrays for all user variables:
-- uservariables['yourvariablename'] = 'Test Value'
-- uservariables_lastupdate['yourvariablename'] = '2015-12-27 11:19:22'
--
-- other useful details are contained in the timeofday table
-- timeofday['Nighttime'] = true or false
-- timeofday['SunriseInMinutes'] = number
-- timeofday['Daytime'] = true or false
-- timeofday['SunsetInMinutes'] = number
-- globalvariables['Security'] = 'Disarmed', 'Armed Home' or 'Armed Away'
