# The right

**New devices must be born open.** Products placed on the market after Sep 2026 must make their data accessible by design.

Data accessibility becomes a product requirement, like safety. When you specify new building systems, 'where does the data come out?' is a question the manufacturer must already have answered.[^eli]
