Generate Dashboard Report

Use this node to capture a screenshot of a ThingsBoard dashboard using a headless browser and save it as a blob entity — for example, generating a PDF or PNG snapshot of a live dashboard to attach to an email report, or archiving a visual record of device state at the time of an alarm.

• Use system reports server — when enabled, uses the system-configured reports server endpoint. When disabled, specify a Reports server endpoint URL directly in this node.
• Use report config from message — when enabled, reads the report configuration from the incoming message data under the reportConfig key.

1. Load the report configuration from message data or static settings.
2. Submit the dashboard capture request to the reports server.
3. Save the screenshot as a blob entity.
4. Append the blob ID to message metadata under the attachments key.
5. Route via Success.
6. On error (invalid config, server unreachable, capture failure, user not found): route via Failure.
