Mh any idea why the other workflows (test, lint, ..) are not running? This looks good, but green tests should be there.

[mpfeil]

Mh good question. Maybe because it is still WIP?

[ubergesundheit]

Mh it should run for pull_request against master branch anyway https://github.com/sensebox/openSenseMap-API/blob/master/.github/workflows/test.yaml#L3-L9
