I have migrated my OH2.5 to OH3 a few weeks ago. Since then, time and again I am trying to start gradually moving my old basic ui sitemap to the new system, but I just cannot get going and end up being completely lost.
By clicking around a bit cluelessly in the overview page, I may have messed up something, but I am not sure if it should build up automatically or not.
I have seen that others have “Overview, Location, Equipment…” Tabs at the bottom of the page. I do not have these.
I feel there should be something in it by e.g. looking here: Building Pages in the OH3 UI: documentation draft (1/3)
Is there a way to “initalize” the overview page again?
My model now looks like this.
The overview page is now completely empty.
On a side note: I also do not know how to get the dimmer to show correctly. It is “physically” a numeric/integer mqtt channel and I used to control it with a Number item and a slider in the classic UI.
