Having no Pi experience I can't really tell how easy it is to install WeeWX on it.

I can nevertheless claim that the Debian package installation (should also work on Ubuntu, Mint and derivatives) is pretty straight forward and flawless. Also, the installation of extensions/new functionality is subsequently much easier. Does CumulusMX architecture provide some sort of plug-ins mechanism?

I am no Linux expert myself. But for that my matter I know nothing about Arduinos and almost nothing about electronics but I am willing to...

BTW, I am with you as far as Weather Display is concerned. It's a messy patchwork. And a resources hog.
