(Classic) Single button + sensor + daylight

The lighting turns on when the button is pressed. Luminaires adjust the light intensity depending on the amount of daylight (daylight harvesting). When a sensor stops detecting the presence the lighting turns off. Use this scenario when you want one button to turn the light on and the other to turn it off (single button mode).

Instructions

Find the following nodes in the Node-RED palette:

DALI2 Devs Common x2
Daylight Harvesting
vertex action x4
vertex cluster

We have two DALI2 Devs Common nodes, one for the On/Off button and the second node for the multisensor. In the On/Off Button node, with button no. 1 we set the brightness to 100% on a selected group. Button no. 2 sets the brightness to 0% (turns off the group).

See the picture below and configure the vertex action nodes on your own. The VA: 100 node should have a priority set to 255 in order to enable daylight harvesting function. Daylight harvesting will then start to work after turning on the lighting from the ON button.

2. Configure the VA: 0 node:

3. In the DALI-2 multisensor node, we have 2 instances The first instance is responsible for presence/movement detection and the second one is a light sensor instance. See the picture below and configure the settings on your own:

Set the t1 and t2 times in the motion/presence sensor section.
Check the Illuminance level checkbox in the Light sensor section.

4. In VA: Motion sensor node select the same group as in the VA: 100 and VA: 0 nodes.

5. Daylight Harvesting node configuration: Daylight Harvesting.

6. Configure the VA: DH node:

Make sure that the Priority is set to “0”.

7. Connect all nodes, link VA nodes with vertex cluster and click Deploy.

What can I modify?

Brightness levels after buttons pressing. Change that in VA: 100 and VA: 0 nodes.
Change the value of Daylight harvesting value.
Change the presence and transition times in the DALI-2 multisensor node.
Optionally if you use a 4-button wall panel, you can add further buttons to e.g. set different brightness levels or scenes triggering.
You may not need a light sensor and can have only an ON/OFF button + OFF from the sensor function. If so, delete nodes that are not needed.
