D4i is the DALI Alliance extension of DALI-2 that standardizes in-luminaire energy, diagnostics, and asset data stored on the driver. D4i-certified luminaires report power consumption and operating data to the control system, turning every fixture into an IoT-ready data node.
D4i connects the protocol cluster to the data cluster: standardized driver-resident data powers analytics and maintenance workflows without proprietary lock-in.
Verify D4i certification per represented product; never generalize one manufacturer's capability across the portfolio.
