Re-connect permanent devices after OH restart

Does anybody know how to reconnect permanent devices (e.g. wall mounted tablets) automatically with openhab after openhab has been restarted?
Doesn‘t matter if it is server-side or client-side

Tasker would be one possibility ?

Hi Wolfgang,
thanks for replying.
What‘s the idea behind this?
tasker polls oh-server if it is available, and if not, tasker sends a command to the browser to refresh the website?

Yes. Either refresh the browser or restart the browser.
