Create a dashboard and send telemetry

A dashboard in ThingsBoard is a configurable interface for monitoring and managing devices in real time. In this step, you will create a dashboard directly in the Edge UI, add a widget to visualize telemetry, and send data to confirm it works.

1. In the Edge UI (http://localhost:8080), go to Dashboards and click Add dashboard (+) ⇾ Create new dashboard.

2. Enter a name and click Add. The dashboard opens in edit mode.

3. Click Add widget, select Charts ⇾ Time series chart, set your device as the entity and temperature as the series key, then click Add.

4. Click Save in the top-right corner to exit edit mode.

1. Go to Entities → Devices and click on your device to open its details. Click Check connectivity.

2. A dialog appears with a pre-configured command for your selected protocol and operating system. Copy the command and run it in your terminal. A 200 OK response confirms Edge received the data.

3. Switch back to your dashboard — the chart updates within a few seconds.
