My last idea: log into your karaf console, do a bundle:list, note the number most left to the line with the tcp binding (if any) then do a bundle:uninstall xxx where xxx is the number for the tcp binding.
I’ve logged on to the karaf console, and I’ve found the tcp binding (ID 188).
I uninstalled it (bundle:uninstall 188).
It doesn’t show up anymore. So whatever I’ve done, seems to be successfull.
However, when I reboot OpenHAB, I still get:
2017-02-22 15:02:30.165 [ERROR] [core.karaf.internal.FeatureInstaller] - Failed uninstalling 'openhab-binding-tcp1': Feature named 'openhab-binding-tcp1/0.0.0' is not installed
Also via PaperUI it is still installed. Uninstalling via PaperUI does not work.
