The Bluetooth® Mesh to DALI Gateway Specification

Unlocking the potential of commercial connected lighting
The Bluetooth® Mesh Networking to DALI Gateway Specification enables D4i certified intelligent luminaires to be provisioned, managed, and controlled on a Bluetooth® Mesh Networking lighting control network, enabling significant advancements in energy efficiency and improvements to the occupant experience. A standardized gateway also removes one of the biggest barriers to realizing the true potential of IoT lighting by allowing data stored in the luminaires to flow freely to building management systems, enabling additional building services and more efficient operation of building management systems, such as HVAC and security.
The collaboration

The Bluetooth Special Interest Group (SIG) and the DALI Alliance have collaborated to specify a standardized gateway to allow D4i certified luminaires to be controlled by a Bluetooth® Mesh Networking lighting control network. The collaboration between the Bluetooth SIG and the DALI Alliance brings together the trade association that oversees Bluetooth® technology, the leading IoT standard for wireless lighting control networks, and the organization responsible for the leading IoT standard for intelligent luminaires.
Interoperability between lighting control systems and intelligent luminaires benefits everyone on the value chain, from manufacturers to end users. The market will benefit from a wider selection of interoperable intelligent lighting components that will help accelerate the adoption of intelligent, IoT-enabled lighting systems in retrofit and new-build environments.
The Bluetooth® Mesh Networking to DALI Gateway Specification represents a key step in enabling lighting control systems to shift from a single-function solution to a platform that feeds building management systems, and helps position intelligent lighting infrastructures as central to satisfying the growing demand for increased energy efficiency and improved occupant experience in sustainable, human-centric buildings.
