Mit der alten Chassis hat das Raspberry Car wenig Möglichkeiten gehabt. Der Servo, den ich für die Lenkung verbaut hatte, ist nicht genau genug und zu schwach. Die Reifen sind aus relativ hartem Plastik und haben auf Teppichböden so viel Widerstand, dass der Motor es nicht mehr antreiben kann. Also muss etwas Neues her. Aber was?

openHab als Deamon starten
Um openHab als Deamon auf dem Raspberry zu starten und somit die Erreichbarkeit des Smart Homes zu garantieren, wird ein Init-Script benötig. Leider bringt openHab ein solches Script nicht von Haus aus mit. In einer Google Gruppe hat Thomas Brettinger ein Script gepostet, mit dem er diese Funktion ermöglicht hat. Dieses Script habe ich als Vorlage benutzt und folgende Zeilen angepasst:
Zeile 24: Korrektur des Pfades
Zeile 26: Benutzer verändertUm openHab dem Autostart hinzuzufügen fehlt noch folgender Befehl:

sudo update-rc.d openhab defaults |
Hier das auf mein System angepasste Script:
