# Adding Devices to Clarity

This page provides general information about connecting edge devices to Clarity. See the [HMS eWON](/clarity/connect-data-sources/adding-devices-to-clarity/hms-ewon-setup.md) page for connecting their devices.

You can access the Add Device flow by clicking the `+` button next to `DEVICES` in the sidebar:

## Device Type and Login

Create a device name and a username and password that your device will use to authenticate itself to Clarity.

{% hint style="info" %}
Each edge device that connects to Clarity has its own unique username and password. This reduces the risk that all of your devices will be compromised because one device password is leaked.
{% endhint %}

### Protocol Types:

* **JSON**: Use this if you're not sure what to select. The JSON protocol type offers several options for decoding plain text data.
* **SparkPlug**: Use this if your edge device explicitly follows the SparkPlug/B MQTT standard.

After filling out the fields, click **Save**:

Once the device is created, Clarity will redirect you to the edit view for your device:

If your edge device successfully connects to Clarity, you will see the connected status at the top:
