After I was way for an hour, I unlocked my screen. Surprise: at the right side of my panel, just left of my date/time indication there was a new icon. Hovering over it it said KDEconnect. I have no idea why it spontanious manifested itself.
Right click did not show any “remove” item. Clicking on it opened a window showing another system, which is in fact the name of another (also openSUSE 15.2) system on the LAN. Clicking left or right, but nowhere anything to delete/switch off/remove.
At last I tried Right click on the Panel and then Edit Panel. Several movements and click. With care, because I never know what does what. In the end I succeeded, while having the mouse over the KDEConnect icon, to remove. But it removed all icons there: Clipboard, the one thar tells me there is unread mail, same for unread RSS feeds and the one with the small triangle that shows “hidden icons”. So I am rather hampered in my workflow now.
Is there anybody who can understand my rather vague story (I am not good when I can not show CLI output) and point me how to restore those little icons left from the data/time?
Next question then is of course how to get rid of the KDEConnect one if that is still there again.
You’ve probably removed the system tray in error. On the panel, right click and choose ‘add widgets’. Look down the list for system tray. It should have a circled 1 in the corner if it’s still there. If it doesn’t then double click to add it back.
If you right click in system tray (be sure not to right click one of the icons) you should see ‘configure system tray’ - choose this. Under entries you can add or remove any of them. Kde connect should be one of the choices. Of course, if you don’t use kdeconnect, just uninstall it.
PS The files are stored in ~/.config/plasma-org.kde.plasma.desktop-appletsrc but it’s not easy to sort out which is which.
To begin with your file pointer. I do not have that directory in ~/.config. The only directory that has the word plasma is ~/.config/plasma-workspace. But that has two empty directories only (env and shutdown).
About your Widget suggestion. Because of the translation I had to search more thoroughly, but I found it. I also do understand now the number 1 in circle, those are the ones I already have. Then I tried to click on it, but that did not do much. In the end I moved it with the mouse and that did it! They are back!
(All the clicking had also created some system usage icons/widget at the right of the clock, but I managed to remove that again. Still much magic for me there >:))
Tidied up my own panel. Removed widgets from ~/.local/share/plasma_icons and replaced them with entries in the window list. No magic whatsoever anymore.
Not always. But an interface that removes a “widget” where I never saw, let alone clicked, a “remove widget” and that then is added by using “add widget”, it not a symmetric user interface. And as long as such things belong to KDE, it is magic. At least in the heads of the UI designers.
Then you may be the person to explain why that KDEConnect icon (apparently inside that widget) emerged all of a sudden. And with inside it the hostname of another desktop wuth openSUSE on my LAN.
And of course why I can nowhere find a possibility to remove that icon.
They make changes and refrain from documenting. They try to support old features. Users end up with a mixture of old and new configuration. Watch for entries in folders ~/Desktop, ~/.local/share/applications/ and ~/.local/share/plasma_icons/. Delete them all and restore only if needed.

The journal tells what happened. Not all clicks go where the user thinks they are going. Select ‘Edit Panel’, move the mouse over the icons and click ‘Remove’.
That is of course one of the things I tried. But because it is gone, I can not repeat that action now. And I hope it will never re-appear.
But IMHO there is still no explanation why it emerged in the first place. And why does it try to connect to another system on the LAN? In fact I find it rather scaring Some sort of desktop software that tries to contact a system in an unknown way. Not only the user (me) was flabbergasted, but the user reported this to the system manager (again me) and he sees this as a security isue until explained.
