OpenHAB 1.x auf dem Raspberry Pi
Erstmal den Raspberry auf den aktuellen Stand bringen und die benötigte Java-Umgebung installieren:
apt-get update
apt-get -y upgrade
rpi-update
apt-get -y install default-jdk unzip
Dann kümmern wir uns um OpenHAB:
(Beim schreiben dieser Anleitung, war gerade die Version 1.8.3 aktuell. Schaut nach, welches die derzeit aktuelle Version ist und ersetzt die 1.8.3 durch die aktuelle Versionsnummer!)
version="1.8.3"
mkdir -p /opt/openhab
cd /opt/openhab
wget https://bintray.com/artifact/download/openhab/bin/distribution-${version}-runtime.zip
unzip distribution-${version}-runtime.zip
rm distribution-${version}-runtime.zip
cd addons
wget https://bintray.com/artifact/download/openhab/bin/distribution-${version}-addons.zip
unzip -o distribution-${version}-addons.zip
rm distribution-${version}-addons.zip
cd ..
cp configurations/openhab_default.cfg configurations/openhab.cfg
wget https://bintray.com/artifact/download/openhab/bin/distribution-${version}-demo.zip
unzip -o distribution-${version}-demo.zip
rm distribution-${version}-demo.zip
./start.sh
Nachdem OpenHAB gestartet ist, können wir und mal die Demoumgebung anschauen. Hierzu im Brower das OpenHAB aufrufen.
Die IP muss vermutlich angepasst werden:
http://192.168.1.10:8080/openhab.app?sitemap=demo
Mit Strg+C
können wir openHAB jetzt wieder beenden.
Damit unser openHAB später nicht als root läuft, geben wir jetzt dem Benutzer "pi" die entsprechenden Berechtigungen um openHAB zu starten:
cd /opt/
chown pi:pi openhab -R
OpenHAB beim booten automatisch starten:
Zuerst müssen wir das Init-Script mit folgendem Inhalt anlegen:
/etc/init.d/openhab

Jetzt die Dateirechte anpassen und für den automatischen start eintragen:
chown root:root /etc/init.d/openhab
chmod 755 /etc/init.d/openhab
update-rc.d openhab defaults
Jetzt kann openHAB mit
service openhab start
gestartet werden.
Bleibt am Ende noch zu erwähnen, das für ein Produktionsbetrieb nicht einfach alle Addons in den addons-Ordner kopiert werden sollten. Kopiert nur die, die wirklich gebraucht werden. Denn beim starten von openHAB werden alle jar-Dateien im addons-Ordner eingelesen. Dies kann bei allen Addons den start auf einem Raspberry, schon mal einige Minuten dauern lassen.
