for the latest openhabian I want to give it a static address.
I know, there are other ways to overcome this but DHCP addresses are in some areas only for mobile devices and not for servers. And, at least, openhabian is a server.
I tried a few things which have been described here around, but nothing really worked for me.
If there is an old method and a new(er) method, I would go for the new method
Kindest regards and thank you very much for helping a beginner,
