# DMX/Art-Net™

With the DMX integration (Art-Net™) you can control DMX-based lighting through the nomos controller and use it in scenes and automations.

**Steps to Set Up:**

1. **Activate the DMX integration:**
   * Click the **“On” button** to activate the DMX integration.
   * The nomos controller will then automatically search your network for Art-Net nodes (interfaces). The devices it finds appear under the **“Discovered Nodes”** tab.
2. **Add a device:**
   * Switch to the **“Devices”** tab and click **“Add Device”**.
   * Choose the matching type: **Switch**, **Dimmer**, **RGB** or **RGBW**.
   * Assign the **DMX universe** and the **channel(s)** (1–512) that correspond to the address of your fixture.
   * Note: Set the DMX address (universe/start channel) on the fixture itself before assigning it.
3. **Control DMX devices:**
   * Once added, you can control the devices directly in the nomos app – for example switching on/off, dimming the brightness, or adjusting colors (RGB/RGBW).
4. **Universe synchronization (optional):**
   * Under the **“Sync”** tab you can mirror an input universe onto an output universe.
5. **Use DMX in automations:**
   * Include DMX devices in scenes and automations, for example to switch lighting moods based on schedules or events.

{% hint style="info" %}
**Important:** Art-Net nodes must be on the same network as your nomos controller to be discovered.
{% endhint %}

{% hint style="warning" %}
**No nodes found?** Check the network connection and the power supply of the Art-Net interfaces.
{% endhint %}

{% hint style="info" %}
**Reachability:** The reachability of the DMX devices depends on the connection to the controller. After a controller restart, the DMX devices automatically report as reachable again.
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://documentation.nomos-system.com/nomos-system/integrator-en/skills/dmx.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
