I’m going to assume that you are running openHAB on Linux. According to this posting: this should be possible. Open the /etc/default/openhab2 file using vi, nano, or any other text editor and add or update the following options to the EXTRA_JAVA_OPTS variable: EXTRA_JAVA_OPTS="-Duser.country=DE -Duser.language=de" Next restart openHAB: sudo systemctl restart openhab2.service or simply reboot: sudo reboot
