Re: ESPEasy-20200328 can't change rule sets
In full-screen mode it appears at the BOTTOM with a window showing the rules to the RIGHT.
If I reduce the width of the window, then it moves to the TOP of the screen.
I don't have an issue with that behaviour.

You can then do all sorts of things with the data... store it on the Pi's SD card (local file), write it to a database (local or remote) or send it to other places.
