Filter for POI type within range of N meter

Sometime the charger is not exactly at a location (e.g. restaurant, fast food) and not associated with it, but it is close by.
Would be great if could filter for all chargers with a restaurant within the range of 200m.

Thanks! This is not really possible to implement efficiently with the current architecture, where the most popular data sources (GoingElectric and Open Charge Map) are loaded from their servers directly, and they don't have any additional POI-based filters in their APIs. But I'll keep this in mind for the new backend, which is currently in development.

Would an approach be possible to get first the positions from EV data sources and in a second step to check the result list against another POI database with restaurants etc. (not sure how such data is available e.g. from OSM).

Yes, but for GoingElectric we use server-side clustering at low zoom levels, so comparing lists locally is not possible. Once such a filter is active, we'd have to disable server-side clustering (which, at a certain point, will mean we have to make multiple requests to load all chargers in the viewport) and always additionally query a POI database for the same viewport, so loading times for large areas would be fairly slow. So it would be better to do this at the server side.
