ls -l /dev/ttyAMA0
crw-rw---- 1 root dialout 204, 64 Apr 22 23:04 /dev/ttyAMA0

be sure that user under which you are running the openhab runtime has access to this file.

In my case openhab. /dev/ttyAMA0 is owned by group dialout.
I had to add the user openhab to group dialout as follows.

sudo usermod -G dialout openhab

Add following line in /etc/default/openhab2 to be sure the serial port is started on service start (java has problem with non-standard ports).


If you have openhabian version of system you can use openhabian-config and check option under serial port -> add java options for razberry.

sudo systemctl stop z-way-server
sudo systemctl disable z-way-server
sudo systemctl restart openhab

Check /var/log/openhab2/openhab.log
