Let me start by saying I am completly new to this. I can not seem to find a post with the ptoblem I am having.
I have setup my raspberry pi using this tutorial
I have been sucessfull up untill connecting mqtt part 7.
sudo nano /etc/openhab2/services/mqtt.cfg
My putty sceen has lines to change. The only items are the get help and exit comand area. I can not change broker url. Is this needed with mqqt 2.4 binding? What do I need to do to correct this?
