Panels have a universal design and are equipped with status LEDs. They are available in 2, 4, 6, and 8 buttons versions.
How to use it in the LMS design?
To use switches in the project, you need to remember the specific Ethernet2DALI limitations.
Additionally, you can use the feedback diode function to monitor the state of the DALI groups. You can program these diodes.
The panels are compatible with the European standard electrical junction box (Ø60). There are two ways of mounting - using stickers or screws. Both are included in the box with the wall panel.
How to commission it?
Wall panels have several diodes. One for each push button and one on the top. The middle-upper diode is used for identification.

Step-by-step instructions
To program logic within the Node-RED tool you need to use a DALI2 Devs Common node, which is available in the node palette on the left-hand side of Node-RED UI.
Click this node to enter the configuration window. Choose the serial number of the device in the Serial Number field. Then uncheck the box (or boxes) at each DALI2 Input Unit. It depends on how many buttons from the panel you want to program.
Then select the mode for each button. For the standard toggle button use Mode: Normal. If you need to create a function of dimming choose Mode:ESDIM.
Then click Done in the upper right corner of the window.
Then you need to find the vertex action node in the palette. Select the group you like to be controlled by this switch. Then define the action you want (single button, toggle button, triple button, etc.).
In order to turn on the appropriate button LED, configure the change nodes, which will work as feedback:
| Info |
|---|
Payload syntax:{“feedback“:{“A1“: B1, “A2“: B2,….}} Ax : button instance number starting from “0“. Bx : LED state (0-OFF,1-ON). |
Remember to connect your flow to the vertex cluster node.
Then click the Deploy button at the upper-right corner of the Node-RED.

This method uses dali2devs node. This node allows you to manage events from DALI 2 device e.g buttons. The difference between this node and DALI2 Devs Common node is that you can only use one instance of the button. On the other hand, turning on appropriate button LEDs is simplified thanks to the usage of vertex feedback node.
Step-by-step instructions
Configure the dali2devs node accordingly. In the Dali2 Device field, specify the button instance you’ll use. Enter the properties tab of the vertex feedback node and select the appropriate luminaire group.
Connect the flow as shown and click Deploy.
