In order to add a device, 6 mandatory and 2 optional fields can be filled. To be able to add a device, all mandatory fields should be filled. The mandatory fields are designated by an asterisk '\*'. When done, click the **Create** button in the bottom right corner to add the device.&#x20;

### Mandatory fields:

1. &#x20;**Device name**: The name of the device. This name is used throughout SolidRed as a unique identifier to keep track of the device. **Note:** Once filled in, the name can not be changed. The "Label" field can be used to show the device under a different name.
2. **Sensor orientation:** the sensor orientation based on the position it is installed related to the asset.
3. **devEUI:** The device's globally unique Identifier in the IEEE EUI64 address space. The devEUI is provided on a file when purchasing the device.
4. **appEUI:** The device's global application ID in IEEE EUI64 address space that uniquely identifies the Join Server that is able to assist in the processing of the Join procedure and the session keys derivation. The appEUI is provided on a file when purchasing the device.
5. **Device type:** The type of device to add. The device type can be found in the device's documentation. Clicking the field will open a dropdown list including all available devices. The device type defines how the device is handled in SolidRed.
6. **Key**: The device specific encryption key. The key is provided on a file when purchasing the device.

### Optional arguments:

## 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://docs.twtg.io/docs/solidred-3.1/entity-management-features/device-management/add-device.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.
