Good evening MDAR,
I was on vacation in July and I must have missed your message dated from 19 July…until tonight 
.
Meanwhile I reinstalled Openhab a few times because an Openhabian upgrade ruined everything. Pi was running hot and no rules where executed anymore. I ran your revisited zip (see last message) but still no Velbuslink connection via TCP/IP. All the rest(OH) is working fine again. I didn’t have a lot of time recently but I’m wondering if others experiencing the same problem?
It’s not an urgent one but if I can help you testing…let me know.
Kind regards and sorry for this dust covered reply!
Jona
