# Positioning Devices in a Room
The visualization function in the nomos system Controller allows you to graphically represent and personalize the structure of a room by uploading an image and positioning devices accordingly. This feature enhances the overview and simplifies device management.
**Steps to Use the Visualization and Position Devices:**
1. **Upload Image:**
* After initiating the visualization function via the "**Visu**" button for a room, upload an image of the room, such as a floor plan or room layout.
* **Step:** Click "**Upload Image**" to select the image to be used for visualization.
2. **Manage Devices:**
* Once the image is uploaded, devices assigned to the room appear as **pink fields** on the screen. Each of these fields represents a device, such as:
* *Lampe Test 2*
* *RTH Test 2* (Thermostat)
* *Steckdose Test 2* (Lighting)
* Current Weather
* These devices can now be placed on the image.
3. **Move Devices:**
* The **pink fields** representing the devices can be freely moved on the image.
* **Step:** Drag each pink field to the location in the room where the respective device is physically situated, e.g., the lamp near a table or the socket on the wall.
* This flexible arrangement helps reflect the actual physical placement of devices in the room
4. **Save Visualization:**
* After all devices are correctly placed on the image, click the "**Save**" button to secure the changes.
* This visualization remains saved and can be edited at any time.
5. **Remove Image:**
* If you want to change or remove the image, you can click the “**Remove Image**” button and upload a new one.

## 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/rooms/positioning-devices-in-a-room.md?ask=&goal=
```
`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.
