Good to have you here! On wettercube.de you now find everything about the WetterCubes in one place: the family from the first WetterCube through the WetterCubePlus to the WetterCube Fusion and the additional module Next, the roadmap and a comparison.
If you want to get started right away: the web installers flash the firmware straight from the browser onto your board, with no detour via GitHub. All guides, settings and help are neatly organised in the wiki.
Which board you need and how to print a case is explained on the page Hardware and case. A matching case for the Fusion is in the works; the free 3D-print file will be available here on the blog and on the hardware page as soon as it is ready.
In the blog I will report on new versions and progress. Questions and ideas are welcome through the contact form.
