@inmg_dmc Hello, if you have Purple Air sensor and have it set as public, we will automatically display it.

Hello @Wauzal, thank you for your suggestion! We will consider it when developing future features.
As a temporary solution, you can mark a station you like as your Favorite (via heart icon by the search tab), so it can be distinguished from the others.

@brunop74 The error is likely somewhere in your setting. The API key has no errors if you correctly copied it from the station detail.

Radar is about real time observations, well available on Windy maps (select "Weather Radar" layer).
As a real time observation, it cannot follow forecast model data computed for the future...
