Openhabian - Arduino via USB

Thank you!
I’ve done this. (call sudo openhabian-config via ssh - done all “10 | Apply Improvements”)

ls -al /dev/ttyACM0
crwxrwxrwx 1 root dialout 166, 0 Dec 30 15:43 /dev/ttyACM0

(I verified with minicom the info is comming in on ttyACM0)

grep ‘dialout’ /etc/group
dialout:x:20:openhabian,openhab

So I think, the permission should be OK.

In an other thread
vzorglub posted for someone other with the same problem “Can you post the serial.cfg file, please?”
It should be in etc/openhab2/services
If it is not there then the binding didn’t install properly

The problem in this thread was (I think) never solved.

I have also nothing like serial.cfg

sudo ls /etc/openhab2/services
addons.cfg dashboard.cfg readme.txt rrd4j.cfg runtime.cfg

I added in (somewhere - I do not remember) some cfg file “bindings=serial” (I could add more bindings comma seperated). This was told in some forumpost.

in PaperUI -> Add ons -> Bindings ->

Serial Binding binding-serial1 - 1.13.0

seems to be installed.

So what can and should I do next?
Thank you in advanced,
Andi
