You need to control the lighting in the room according to the presence of employees. You have a multisensor which allows you to detect the presence and movement of people. Using Node-RED you can program how the luminaires have to operate when the movement was detected and also when the room is empty.

Instructions

  1. Find the following nodes in the palette on the left side of the Node-RED.:

  • DALI2 Devs Common

  • vertex action

  • vertex cluster

2. Drag the nodes and drop them onto the workspace.

3. In the DALI2 Devs Common node, in the Serial Number field, select the multisensor.

4. Clear 1st checkbox to be able to program the Motion/presence sensor.

5. Define presence and transition times for the multisensor.

6. In the Vertex action node, select the mode as a motion sensor.

7. Select the group you want to control. Define actions on Presence, Transition, and No presence events. Below you have actions examples. On presence detection the lighting turns on, then when presence stops being detected (transition time) the luminaires are set to 10% of brightness. Finally, after the transition time, when there is still no movement, the luminaires go to their minimum brightness level.

8. Link all nodes together. Connect Dali2 Devs node output to complementary vertex action node and then connect the output of vertex action nodes to the vertex cluster node.

9. Select Deploy to save the program.
