A simple light switch that turns on all the lights and off everything hooked up to the Powerbar system.
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
done
It runs from the /etc/rc.local
Currently it only polls once every second so please be patient . .
As you can see from the code the safest way to boot the thing is with the button in the OFF state and after it is booted switch the lights ON.
This is not meant to replace the Lightswitch project, but just a quickly built addition to switch on the lights when you enter, and switch off everything when you leave without the need to go to powerbar.ti
