Do you have an idea which of your rules does throw this error? It slightly looks like a scheduled rule using a cron expression. Would be nice to know how the code looks like.

If you are not able to identify it please open an issue on GitHub for it. Thanks.


Did Somebody Upgrade on Ubuntu from 2.5.x to 3 and could Share some Details about the steps to perform?
I understood I can Just install OH3 via apt get and it should Copy over all My Text config? Is that true for Things, items, Scripts, Sitemaps, Rules, persistance and DB configs etc?

Will the install also automatically deactivate the oh2 Service?

I use many bindings with over a 1000 items and have some fear how Long I will need to clear Out all little issues then :laughing:

Check the release notes and scroll to the section titled Upgrade.

Before you do that, check the entire release notes carefully especially if you’re “using many bindings” - v1 bindings will not work.

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
