Hi Lasse. The answer to your specific question is that we do not currently use data collected from any station (public or private) for any purpose other than internal analysis to facilitate individual station QC and auto-calibration as well as general improvements to sensor hardware and data processing.
That said, we do intend to use anonymized (non-personally-identifiable) data collected from the smart weather network in other data products such as forecasts, hindcasts and nowcasts. But we will only do that with consent from the individual station owner. Regarding personally-identifiable information (PII), and ways to share your data while maintaining your privacy, please see the discussion here: Station Privacy and PII Concerns
