Features of Zhaga-D4i interface standard Easy to add or upgrade sensors and/or communication nodes:– Enables future-proof luminaires that can keep pace with rapid developments in digitalnetworking and sensing technology. Intra-luminaire DALI-2 bus:– Enables bi-directional interaction between sensors and/or communication nodes and LEDdrivers using the well-established and standardized DALI protocol. D4i drivers are smart:– Able to report operational and diagnostic data to an external network, and can provideinventory-related information about the luminaires. IoT connectivity:– With a suitable wireless communication node, the luminaire is able to interact with an externallighting-control network, and to participate in the IoT.5
