Hey there,
i just installed installed openHab 2.2.0-1 on a Qnap TS-251. The installation worked and I can access Openhab.
I created a user account in the NAS with RW permission to the share where openHAB is installed and I installed the KNX binding.
Its possible to access the conf folder and edit and save for example the items file. But it
s not possible to edit and save the knx.cfg file. Does anybody have an idea whats wrong?
Problem solved! I had to make the changes with the admin user.
