With this functionality, you will be able to use light sensors to adapt luminaire power to the current daylight level. The light intensity will be kept constant and luminaire power will automatically adjust to a given value of light intensity.
Instructions
Find the DALI2 Devs Common, Vertex action, Vertex Feedback, Daylight Harvesting, and Vertex cluster node in the palette on the left side of the Node-RED.
Drag the nodes and drop them onto the workspace.
In DALI2 Devs Common node, in the Serial Number field, select the multisensor.
Uncheck the Light Sensor checkbox. Check the Illuminance level option.
5. Go to Daylight Harvesting node. Select the Feedback group which will be controlled and give feedback on current lux value. Set number of luxes in Daylight Harvesting value field and choose toleration (in luxes).
6. Go to vertex action node. Set mode as Direct Value and as action select Set brightness (scale logarithmic). Select the same group as for the Daylight Harvesting node.
7. Uncheck the Priority checkbox and set the priority as 0. This will enable the daylight harvesting function to operate after the lighting will turn on (triggered by multisensor or by switch).
8. Link all nodes together as in the screenshot below.
