What this does not say

Quoted verbatim from the section’s warnings field, exactly as the API returns it. They are not translated: a translation would show something other than what your response actually contains.

Straight-line EPSG:25833 distances to traffic sensors within 5 km. No driving distance and no road-relevance guarantee.
This is the identity-and-distance list; the sensors' own observations are in the traffic section, computed from the same match.

Fields

2 of 3 fields are value fields — the ones that decide whether a record actually says anything. The rest are context: identifiers, codes and timestamps. Fields marked “open” return values to anonymous callers; the rest require a key.

Field	Type	Role	Demo
sensor_id	string \| null	context	open
sensor_name	string \| null	value	open
straight_line_distance_m	integer \| null (m)	value	open
