/dev/ttyUSB0 No such port - AGAIN

In my testing I found things usually worked when starting OH but failed when a binding was restarted. It could not find the serial port.

22

Are you running the latest version of the binding?

Is nrjavaserial (bundle) running in openHAB?

23

Yes it is the latest version and yes it is runing:

openhab> bundle:list -s | grep serial

24

Why are there 2 versions running?

I’m out of ideas and time this morning. Maybe try searching the forum for “serial port not found” or similar, not involving MySensors.

26

@CrazyIvan359 as mentioned by @Bruce_Osborne

Try using the console stop/remove one of them, could be a conflict not seen in logs, see if that helps.

They may need to restart OH too? I duobt just stopping a bundle would be sufficient. Is there a way to stop a bundle from auto-starting with OH?

28

Not that I know of.

Just pick the one you want to use, then from the console use
bundle:uninstall to remove the other.

29

With the extra complexity I would try a few things to troubleshoot. First - if you don’t have it already I’d grab the Portainer docker app and run it. This is a web admin GUI for docker and it will allow you to not only edit / redeploy current containers but also enter a command shell within the container itself. This way you can confirm the serial port is there and accessible within the container. If all is well there then you can go on to troubleshooting openHAB. When jumping into the container you can go in as root so all permissions should be fine - as long as docker is running as a user with access to the ports. From what I see In your config I’d just confirm that you have the group IDs matching and openhab is running as a user with access to the tty ports

When I do this both bundles will disappear…

Use the bundle number 278 or 279 to identify the one to remove.

I already use Portainer and yes I can connect to the docker container and can manualy read from ther serial port by using cat /dev/ttyUSB0

33

Ok that worked one of the bundles is now removed however still no luck

Did you restart OH after removing the bundle?
