--[[Scripts receives temperature value from the temp & hum sensor located in the garage
	If received temperature value is lower than preset value (default 3degC), notification and email is sent.
	Interval of sending email notifications is set 24h by default (86400s)
	Setting debug variable true, script prints values that are coming in with device changed table
	Own variable GarageEmailSentSystemTime (type: Int) is used to store time in system seconds when last notification and email was sent
	Own variable GarageTempLimit (type: Int) is used to store temperature limit (min. value)
	Content of the script is executed only if device event came from sensor mentioned in devicename variable]]
