What the owner is owed · EU Data Act

The data your building makes is yours to take.

Free, machine-readable, continuous — on request, at the same quality the vendor sees.

Every reading, event and log your building generates is accessible to you by right — not as a favour, not behind a professional-services quote. The data holder must hand it over without undue delay, in the same quality it has itself.
