script_device_presencedetection.lua

--[[Intention of this script is to arm security system if all mobile devices are out of home (= no one is at home).
The script also disarms the security system, if armed, when at least one of the mobile device is detected.
Device detection is based on Presence detection script which can be found from the Domoticz wiki (https://www.domoticz.com/wiki/Presence_detection).]]
