# Adding a KNX Device

Use the **Add Device** button to integrate **KNX devices** into the **nomos system Controller**.

**Steps to Create a New KNX Device:**

1. **Add Device:**
   * Click on the **Add Device** button. A window will open for setting up the device.
2. **Name of the Device:**
   * Enter the desired **name** for the device, for example, **"Licht Test"**.
3. **Select Room:**
   * Choose the **room** where the device is located. In this example, it is the "**Test**" room.
4. **Select Device Type:**
   * Click on the drop-down menu labeled **Type** to select the device type.
   * Various **device categories** are available:

     * **Lighting:** Dimmer, Light, RGB
     * **Ventilation:** Fan, Fan with Speed Control
     * W**indow Shading:** Shading, Shading without Position, Shading without Angle
     * **Heating & Cooling:** Heating, Heating (Setpoint Offset), Air Conditioner, Thermostat Variant TA
     * **Switches:** Trigger, Switch, Scene

5. **Enter Group Addresses:**

   * After selecting the device type, the columns for the group addresses available for this device will appear.
   * In the individual fields, you can now add your desired group addresses.
   * It is not necessary to fill in all states or values for the desired device to appear in the app/Visio. You can also enter only individual group addresses (e.g., ON/OFF), and only this function will be available in the app/Visio.
   * Note that the correct data types for the desired group addresses must be set in the ETS. If they have an incorrect DPT rate, it will be transferred to your nomos system Controller, and the function of this group address may not work correctly.
