How this maps to the API
We hide sensor numbers. Behind the scenes we use these raw endpoints:
CSV/api/raw/records
Externaldst=23
Internaldst=21
Barodst=19
HealthNDJSON payloads recommended
Different stations may use different dst values for "External". We auto-detect using /api/latest and choose dst=10 (WLL) or dst=23 (Console) when possible.
