(Classic) Dimming button
In Node-RED we can program any DALI device such as buttons, multisensors, relays, etc. Let’s say that we need to program a 4-button panel. Buttons will be responsible for:
turning on the light
turning off the light
dimming down the light
dimming up the light

Instructions
Find the following nodes in the palette on the left side of the Node-RED
DALI2 Devs Common
vertex action x4
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 panel you want. In this field, you have a list of all DALI devices found by your Vertex controller.
Make sure that the multisensor is properly connected to the Vertex. If not, you won’t be able to set up the parameters. The device with “no communication” status is marked as “NC” at the beginning of the name.
4. Below you have outputs of every Input Unit device - normally they are disabled. Clear 4 checkboxes to have 4 buttons to manage. Set the Mode as Normal for buttons that trigger constant light and ESDIM for dimming buttons.
5. You have 4 vertex action nodes for the same number of buttons. In these nodes set:
1st button for turning on the light:
Set the name as e.g. ON. Then select the Mode as Single button. Then you need to define action as Recall max level and choose the luminaire group you want to control.
2nd button for turning off the light (OFF):
Here, you need only to change the action to Recall off.
3rd button for dimming:
Set the name as e.g. Dimming down. Then select the Mode as Dimm button. Select the first action as Set brightness, e.g. 80% - this is the brightness level you want to start dimming. The second action set Step down cyclically. In this configuration with one click, you set 80% brightness level and when you click and hold you can dim it down to the preferred level.
4th button for Dimming up:
Set the name as e.g. Dimming up. Then select the Mode as Dimm button. Select the first action as Recall min level - this is a brightness level you want to start dimming. The second action set Step up cyclically. In this configuration with one click, you set a minimum brightness level and when you click and hold you can dim it up to the preferred level.
6. Link all nodes together. Connect Dali2 Devs Common node outputs to complementary vertex action nodes, and then connect the outputs of vertex action nodes to the vertex cluster node.
After you select the Deploy button - the blue dots on the nodes should disappear. The green squares will then appear to show the current status of the devices. It means that the viewed flow is already sent to VERTEX.
