# Z-Wave

The Z-Wave integration allows you to connect and control Z-Wave compatible devices directly through the **nomos system Controller**.

A **Z-Wave USB dongle** is required for the direct connection of Z-Wave devices to the nomos system Controller.

Since Z-Wave is a wireless protocol, it's important to pay attention to the physical placement of the controller. The nomos system Controller (with Z-Wave USB dongle) should be placed centrally in the building to ensure **optimal range and signal strength** in all directions.

{% hint style="warning" %}
**Important:** Use a USB extension of at least 30 cm between the dongle and the nomos system Controller.
{% endhint %}

**Z-Wave Integration:**

1. **Activate Integration:**
   * Click the **on button** to activate the Z-Wave integration.
2. **Manage Devices:**
   * This button opens a menu where you can manage the available Z-Wave devices. Here, you can add, edit, or restart the network scan to find hidden devices. When pairing devices, make sure to refer to the manufacturer’s instructions and user manuals for each product. Depending on the manufacturer, certain steps may need to be performed directly on the device.
3. **Remove Device:**
   * This option allows you to remove Z-Wave devices from the network. Make sure to **correctly remove the device from the network** before physically disconnecting it to avoid communication issues. Again, refer to the manufacturer’s instructions and user manuals for specific steps that may need to be done on the device itself.
4. **Network Update:**
   * This button is used to update the Z-Wave network. This can be helpful when new devices are added or when the positions of Z-Wave devices in the building change.
   * A network update can optimize the connection between the devices and the control center.
5. **Reset:**
   * This function completely resets the Z-Wave network and removes all added devices.
   * **Warning:** This function should only be used if all devices are removed and the network needs to be set up again, as all configurations will be deleted.

{% hint style="info" %}
**Notes:**

* Z-Wave devices communicate through a mesh network, meaning each device can relay signals to other devices to extend the range.
* Before resetting the network, make sure to back up all important data.
* When making changes to the network, use the “Network Update” to optimize communication between the devices.

# 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/z-wave.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.
