Has anybody an idea why it crashes ?
After the crash I can turn the lights on (with the app or classic ui) but if I turn on the lights with LCN (Wallbutton) openhab does not recognize it.

When I restart the pchk (LCN-Software) and Openhab the log says Authentification failed, so that I had to reinstall the service

Hi Jörg,

i know this problem from my 1.8.3 installation. I restart the openhab service, but not to reinstall something. What does you mean with “reinstall”.

But i have no idea why this happen. In case i work on the openhab settings, the problem occur much more often, instead of the normal daily workload.
Sometimes i work with a 2. “development system” at my openhab installation parallel. This might force the problem sometimes. But i don´t have a resilient statistic about it.

On the other hand, i had problems with the installation, because some of my LCN ModuleID comment had german “Umlaute”. Not a joke! I removed them and the system was stable!

Regards
Ralf
