iPhone presence detection

[npinguin]

Hi

I am looking for an iPhone presence detection solution.

I found many iPhone detection bash scripts like this one

Code:

script (/opt/openhab/iphonedetect.sh)
#!/bin/bash
MAC=${2//-/:}
declare -a DEVICES
hping3 -2 -c 10 -p 5353 -i u1 $1 -q >/dev/null 2>&1
DEVICES=arp -an | awk '{print $4}'
CHECK=$MAC
if [[ ${DEVICES[*]} =~ $CHECK ]]
then
echo "ON"
else
echo "OFF"
fi

[*]


But nothing in lua.

Did anyone over here already implemented a script and wants to share this?

Thanks
Nicky
