This is related to Upgrade from 3.4.3 to 5.1.3: habpanel shows black screen
However, since then I read the docs, forum, tubes, AI and nada; I was unable to fix it. Worked on 3.4.3; does only work on my dev machine; no other browser or devices.
I am unable to find the “star” or any UI setting to set a default page. I wonder how this worked before.
Any hints appreciated.
Did you try this:
?
Sorry, can’t test, not using HABPanel anymore 
Thanks, I found this link too, but it made no difference to the clients if I set it to true or not; unless a restart is required. If the latter is the case, I will not use it, as my system is production and I won’t restart it like a yoyo to experiment. 
I set this up years ago; it did what I needed it to do.
So, given this experience, may I ask what interface you are using?
Do we know what most are using? I may well switch.
You can probably get away with just restarting the HABPanel bundle. I have no idea if a restart is required, but it often is when caching is involved.
I would assume that those that don’t use sitemaps, mostly use MainUI itself. You can make custom layouts, widgets etc. there as well, you should be able to do more or less what you do in HABPanel.
Thanks… MainUI = BasicUI?? I never paid much attention to UIs (when automation works, there is not much really a use for it); so despite of a decade with OH, this is an area I don’t know much.
I uninstalled HABpanel. and installed again; no change in behaviour.
I just installed a new browser; same result: black.
I will do some research to figure if the UI panels works and how to manage it; but if it is these basic (boring) cards (like on the OH demo server), then “no thanks”. There is a market place… I have to see/learn what technology it is using.
Anyway… looks like I have to dive into this (what I have avoided for so long)
BasicUI is the one rendering sitemaps as far as I remember. PaperUI and all the others are history, MainUI is that name of the “regular” UI in OH since version 3.
You can get MainUI to display information in quite flexible ways, using custom widgets etc., but I personally think there is much to be desired on the layout front. It’s dictated by Framework7, which MainUI is built on top of, who thinks that “mobile UIs”, especially Google’s, is “all that matters”. So, they don’t make it easy if you don’t like this “minimalistic” design. You can do pretty much anything using custom CSS etc., but it feels like you have to “fight it” instead of “work with it” IMO.
Because getting MainUI to behave if you don’t like the one “design” it has means a lot of frustration, I’ve attempted and given up multiple times myself. So, I still use a combination of sitemaps and HABPanel 
Thanks.
I have decided to ditch HABpanel and go with MainUI. Just started building my first page to replicate my HABpanel. (It/fonts render nicer on the rPi panel)
I personally don’t like fancy graphical stuff, so I am using Sitemaps with BasicUI.
A lot of visualized data on a tiny little smartphone display, very easy to create and maintain:
Also Sitemaps are sufficient for some graphs:
And if i need more data on a single graph:
I have one Android tablet on the living room wall to see and control some data, but mostly we are using speech control through Alexa and the Matter binding.
Nice; I use the sitemaps too, on PC and iPhone; but these info panels are strategically places where we do not have devices.
Now my replacement is complete!
Six hours for using this the first time is acceptable
PC view: (which we do not use)
RPi view
The bold and big is for us oldies (70) to read this from 3 m (10 ft) away
You need to go to http://openhabian:8080/overview/ first in the same browser where you want to run habpanel. Then login to Openhab. If you now call Habpanel you will have the star to configure your Habpanel pages.
