A simple light switch that can turn on and off the Powerbar lights.

It's a simple GL-Inet device running some curl and bash magic

#!/bin/ash

echo 20 > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio20/direction

state=`cat /sys/class/gpio/gpio20/value`

while true
do
        if [[ `cat /sys/class/gpio/gpio20/value` -eq 0 && $state -ne 0 ]]
        then
                curl -d state=Off http://powerbar.ti:5000/preset/alloff
                state=0
        fi
        if [[ `cat /sys/class/gpio/gpio20/value` -eq 1 && $state -ne 1 ]]
        then
                curl -d state=Off http://powerbar.ti:5000/preset/lightson
                state=1
        fi
        sleep 1
