  • Issue of the topic: Homematic Binding doesn’t work anymore. I installed some more actors and having now round about ~160. I wanted to add these actors to my OH configuration via the thing files. After adding these actors (RC8 und OC8) the connection to the bridge is not working anymore. I tried it also only with a bridge in the thing file and with adding the Bridge via Paper UI. The autodiscoverd bridge is connected and online. If I search for the other things, i getting a buffering error, see under this post. Getting the same error, if I try to connect the brigde with my OH3 test system.

Has anybody a hint for me to reactivate the homematic connection with my things?

You could try the test version of the HM binding version 2.5.13 from here: GitHub - MHerbst/openhab-addons-test

I am not absolutely sure whether I solved the problem already in this version.

It is definitely solved in version 3 binding where you can configure a larger buffer.

Thanks for the Link,
i installed the 2.5.13, Buffer Error is still there.

On my test system with a 3.10 Snapshot i added your jar to my /usr/share/openhab/addons. I can find it in the console but not in the webui. How can i add things then?

See my comment here: Debugging Homematic IP: no updates on some HmIP devices after some time - #14 by MHerbst

If the binding is active it will automatically detect the CCU as bridge and after you have configured the bridge (see add-on documentation how to increase the buffer size) the other devices will be detected.

Thanks, its working with the Snapshot 3.1
