Is there a way to remove the old bindings, to get rid of the following messages?

2020-12-22 17:35:14.583 [WARN ] [core.karaf.internal.FeatureInstaller] - The binding add-on 'http1' does not exist - ignoring it.```

If you have addons.cfg, remove it from that file. If not or if that doesn’t work, remove it from $OH_USERDATA/config/org/openhab/addons.config

Dear community members,

this thread is for posts of general interest and specific to the OH3.0 release ONLY.
Don’t post your personal issues or on stuff that isn’t really new in OH3.0.
If you keep doing, this quickly becomes a pile of text and waste of time for all of us
so please stay focused and mind the posting rules. Thank you.


Hello. what about telegram action? will it work? Or I should to make script for send messages?)

Hy Philipp
How do you resolved the issue? I have the same problem that the system started but no openhab is available @ ip-address:8080

@J-N-K After upgrading to OH3, I get a WARN from a HTTP Thing. Nothing changed in the configuration, this worked in OH2, with the HTTP2 binding (of course it was an older version, but I can’t say for sure which one was that).

Requesting '' (method='GET', content='null') failed: 403 rate limit exceeded

I would interpret this as too many requests in short time.

Yes this seems like so, but I have not changed anything in the config and in OH2, the same refresh rate did not caused this. I will try to increase the refresh rate.

Java didn’t got installed. (was still on 8)
check in terminal: java -version
you need java 11, if its not installed, its in openhabian config = Menu 46

Is there any issue with semantic classes and the registration at Google Assistant via I described the issue here: OH3 MainUI: How to register (and exclude) items for Google Assistant and Amazon Alexa?. In short, any Tradfri light included via MainUI with semantic class “lightbulb” automatically seems to receive tags that register them with Google Assistant which is not desired for me.

I’ve just downloaded OH3 onto a test Raspberry and so far everything seems to be working fine. One question though, is it possible to add Things textually like it’s possible to do with Items under the “Developer options”?

I have maybe a hundred MQTT things (shellies) that are all textually defined in my current OH2.5 setup and most of them are just copy-paste with an incremented number or similar. It would be a pain (to put it lightly) to manually enter them all and then link them to equipment.

In general, is creating “equipment” in batch processes possible?

No you cannot batch create Things (from text form) for the time being like you can do with Items.
But OH3 just works as OH2 used to so putting up your .things files will make them available in the config as it used to in OH2.

I did.
It was no issue at all.

  1. I updated Ubuntu to 20.04 LTS (before it was the former LTS version)
  2. I installed JRE 11 (Zulu) after adding the repository
  3. I installed OH3 package after adding the repository. OH3 did the migration of OH2 during this step.
  4. I purged the OH2 package
  5. I puged the JRE 8 package needed for OH2
  6. I reinstalled the OH3 package to fix the issue caused by the removal of the user openhab in step 4
  7. Rebooted

Everything was fine.
