Embassy of Nerdistan Tuerstatuserkennung

readme.txt

Dieser Code läuft z.Z. auf einem TP-Link-Router, an dessen Reset-Button-Port ein
einfacher Fischer-Technik-Taster hängt.

1. Passwort in upload.sh anpassen.

2. Dateien kopieren:
handler.sh -> /etc/hotplug.d/button/42-reset-tuerstatus
upload.sh -> /root/tuerstatus

3. Cronjob fuer /root/tuerstatus anlegen

handler.sh

#!/bin/sh

LED='/sys/class/leds/tp-link:green:qss/brightness'

if [ "$BUTTON" != reset ]; then
	exit
fi

if [ "$ACTION" = pressed ]; then
	echo 0 > /tmp/tuer_offen
	echo 0 > "$LED"
elif [ "$ACTION" = released ]; then
	echo 1 > /tmp/tuer_offen
	echo 1 > "$LED"
fi

upload.sh

#!/bin/sh

SECRET='secret'
URL='http://embassy.ccchb.de/status/door/set'

if [ ! -r /tmp/tuer_offen ]; then
        exit 1
fi

OFFEN=$(cat /tmp/tuer_offen)
wget-nossl -q -O - --post-data="secret=$SECRET&isopen=$OFFEN" "$URL" | \
        head -c 4096 > /tmp/tuer_lastlog
echo $? > /tmp/tuer_exitstatus
