Waveshare has recently launched the DALI2 expansion Module for ESP32-Pico series boards. The board is designed to enable DALI communication for customized control of multiple lighting groups. This new board is compatible with various ESP32-based modules such as ESP32-S3-Pico and similar boards like the ESP32 PowerFeather which we have written about in our previous posts. This new module connects to the board via email sockets and the screw terminal is used for connecting external DALI devices.

DALI or Digital Addressable Lighting Interface is a standard protocol for controlling lighting in building automation systems. The newer DALI2 version improves on the original by offering better interoperability, multi-master configurations, and improved energy management. DALI2 also supports bidirectional communication, allowing controllers to both send commands and receive feedback from lighting devices, enabling more advanced automation and diagnostics. For more details, you can check Wikipedia.
