OH3: Binding replacement via addons folder

Add-ons Bindings
1

Dear community,

just one short question from my side. Does anybody know (or has tried it him- or herself) whether it’s still possible to place binding files in JAR format directly into the addons folder? (In my case OH seems to ignore the files.) I’m using OH3 M2 in the docker-alpine container.

Thanks and Regards

You realize Docker-Debian is the default and the recommended? That is because the Alpine containers use openJDK & the Debian ones use Zulu,

Thank you for your reply. I’m aware of that difference but I’m testing some bindings in different constellations/environments and have been assuming that the java version shouldn’t have any influence on the addons folder handling. Am I wrong?

4

Generally the functionality of OH is more compatible with Zulu than openJDK. I believe it is developed with Zulu.

5

Ok, copied that. I switched to the debian container but still no reaction to changes in the addons directory.

6

Are you sure you select the right folder? It works for me on Debian (not docker) and Windows, so very unlikely it doesn‘t work in another Debian environment.

7

I think it’s the right folder as it was working in OH 2.5 before. But maybe another environment variable has to be set?

8

That‘s the wrong one. It‘s now named openhab/addons
not openhab2/addons

In docker there are volume mappings which have to be maintained, so I do use the correct openhab/addons folder.

Just a question to excluse everything. You do have the openHAB 3.0 version of the binding and not the openHAB 2.5 version?

Thank you four response - I really appreciate that. Both bindings were taken from the 3.0.0-snapshot branch. In case of incompatible binding files shouldn’t there be any comment in openhab.log?

Btw. I’ve read your gread summary concerning 3.x Bindings:

I should point out that when a jar is in the addons folder of openhab 3, it does not show up in the installed list. It is best to look for it in the INBOX and pressing the PLUS icon. I raised this on GitHub as an issue.

That is the same in OpenHAB 2. Manually installed addons do not show in the Paper UI.

Can anyone approve, that a jar binding in the addons folder leads to a log entry in openhab.log?

No. No log entries on my system. But the bundle shows up in list on the console.

The addons folder where? OopenHAB3 uses different folder names.

openHAB2 bindings will not work with openHAB3.

Looking at the binding list where? Manually installed bindings only show as installed in the Karaf console.

It is difficult to tell what is wrong.

Yes I know all of that. I don’t have old folders.
I add .jar file to /etc/openHAB/addons/

And I check bundle:list in karat console.
Even after reboot of RPI this binding isn’t adding to list, and it doesn’t appear in any place in new UI.

Maybe you could add some details concerning your problem:

  • What binding are you talking about?
  • Does the binding version match the OH-version?

If the binding is not compatible (maybe wrongly compiled) the binding will not start and you will get no information openhab.log. If the version is correct but there is a dependency error during initialization you should see an error in openhab.log
