I am new to OpenHAB and I have a question. When I type xxx.xxx.xx.x:8080, the main page appears, but the Location, Equipment, and Properties tabs, as you can see in the picture, do not show up!
There is very little user based access control in openHAB. For the UI, there are basically just three settings: not logged in at all, logged in as a user, and logged in as an administrator. The not logged in user has only access to the overview page and any pages in the side panel that have been set as accessible. But, under Settings → API Security, there is an option, Implicit User Role. If you turn this on then not logged in users will be treated the same as logged in basic users.
