Multiple Devices

Why do I have to reconfigure the dashboard on every device?

Which dashboard are you talking about ?

My guess HABPanel

I’m quite new to this topic, so I don’t know which dashboard name it is. The only name I have is “Openhab”.

Any other information/image?

its the standard openhab dashboard

If it is the “standard” dashboard (reachable via ip:8080 or
it should be the same on all devices.
