# Based on the excellent community work here : https://www.domoticz.com/forum/viewtopic.php?t=6264
# Adapted to my configuration
# Last Update 20160903
# Used to detect if smartphones are in by l2ping on bluetooth and if no response search for the smartphone in arp table
## Installation ##
# Add this script in the /etc/rc.local like that :
# /path/to/your/script/script.sh BTMAC WiFiMAC SwitchID &
# ATTENTION the "&" is very important !!!
