If you work with modern building automation, you know that bridging the gap between a technical backend and a sleek, user-friendly frontend can sometimes require a little bit of custom engineering. Recently, I was looking for a flawless way to control DALI2 DT8 RGBW luminaires through a graphical interface. Specifically, I needed a solution for Node-RED Dashboard 2.0 that communicates directly with the KNX Ultimate node using the 6-byte combined group object (DPT 251.600 Color Triplet). Standard dashboard color pickers often struggle with the separate white channel or don't format the payload exactly as the KNX bus expects. To solve this, I built a custom Template node utilizing Vuetify, and I’m sharing the code so you can drop it straight into your own projects. The ETS 6 Setup Before diving into Node-RED, ensure your actuator (or DALI gateway) is properly configured in ETS 6. You want to use the combined 6-byte group object for RGBW. This allows us to send the red, green, blue, a...
