After having given OpenHAB a go, I like the large number of systems it supports. One thing that I am not a fan of is the user interface either from the app or the web interface. As such I was wondering if it were possible to create my own GUI and what it would require? IS there any documentation on how to have the UI connect to the server?
I am a bit new at this, so I'm sorry if I am asking something very obvious - to me, so far it's not yet obvious.

Thanks!
