I tried to upgrade to OH 3.1.0 M4 and tried also 3.1.0 snapshot. In both environments the innogy binding does not connect at all. The binding connects with release 3.0.2, although it often gets disconnected in the night, followed by a timeout. It does not automatically reconnect without a restart of OH, but at least it’s running. Can I deliver logs? I can upgrade again and send you any logs for a further analysis of the problem, if this helps
BTW: if someone has an idea, why the binding goes offline in the release build, it is highly appreciated. I have installed the certificates as documented and followed all the instructions written in this forum. Without success. Interesting is, that the deconz binding goes offline as well, but this is reconnecting.
