EU Data Act · Chapter II · Business to Consumer and Business to Business Data Sharing
Article 3
Obligation to make product data and related service data accessible to the user
Precise reading
Connected products and related services must be designed and provided so that product and related-service data (including metadata) are, by default, easily, securely, free of charge, and where relevant and technically feasible directly accessible to the user, in a comprehensive, structured, commonly used, machine-readable format. Pre-contract transparency duties about the data apply. Bites for products/services placed on the market after 12 Sep 2026.
A summary of the operative demand, not the statute.
Plain reading
Data by design becomes a product requirement, like safety. The building's edge devices must be born legible to their owner.
