Interoperability certification in the works for IoT-connected lighting

February 1, 2019 – The Zhaga Consortium, a global lighting industry association, and the Digital Illumination Interface Alliance (DiiA) are jointly developing a certification program to ensure interoperability between LED luminaires and components for Internet of Things (IoT) applications.

The program will define ‘smart luminaire’ interfaces, based on the Digital Addressable Lighting Interface (DALI) protocol and complementary specifications from both organizations, including recently published DiiA specs for integrated power supplies and data storage and retrieval for energy reporting and asset management.

The goal is to simplify the addition of wireless communication nodes, sensors, drivers and other components to LED luminaires with plug-and-play interoperability. The program will start with outdoor lighting before moving indoors.

“Our joint certification program will provide the entire value chain with confidence in multi-vendor product interoperability,” says Ruud van Bokhorst, general manager (GM) of DiiA. “It will reduce complexity and add value for end users, allowing upgrades of digital functions for smart luminaires.”

Certified products will carry a mark indicating interoperability. Further details are to be announced in the second quarter (Q2) of 2019.
