Controling Homeautomation devices using wifi presence

This guide is not finished yet. I'm working on it :-)

This is a guide describing how to set up a device in Homeautomation that is automatically turned on or off based on whether a certain MAC address is connected to B3's wifi or not. This could then be used in the Homeautomation scheduling to turn other devices on or off based on this information.

First, copy the text below into

#!/bin/bash

HomeAutomationUrl="http://192.168.168.1/homeautomation/"

# Devices that affects HomeAutomation
homeDevices[0]="84:00:d2:e4:3b:9f" #Xperia Ray
homeDevices[1]="d0:df:c7:fd:8d:ea" #Galaxy Tab

# HomeAutomation device ids
HomeAutomationDeviceIds[0]="20" #Xperia Ray
HomeAutomationDeviceIds[1]="21" #Galaxy Tab

connected="AP-STA-CONNECTED"
disconnected="AP-STA-DISCONNECTED"

countHomeDevices=${#homeDevices[*]}

date >> /var/log/hostapd.log

for (( i=0; i<=$(( $countHomeDevices -1 )); i++ )); do

  if [ $3 = "${homeDevices[$i]}" ]; then

    connectionState=0

    if [ $2 = $connected ]; then
      connectionState=1
      echo "$3 Connected!" >> /var/log/hostapd.log
    else if [ $2 = $disconnected ]; then
        echo "$3 Disconnected" >> /var/log/hostapd.log
      else
        echo "What happened now?" >> /var/log/hostapd.log
      fi
    fi

    $(wget -O /dev/null -q ""${HomeAutomationUrl}"ajaxinterface.php?do=toggleStatus&status="${connectionState}"&deviceid="${HomeAutomationDeviceIds[$i]}"" )
  fi

done
