Harness the power of your Obd2 Torque app and Node-RED to create a real-time vehicle data dashboard. This guide will show you how to seamlessly transmit data from Torque Pro directly to your Node-RED server, allowing you to visualize and monitor your car’s performance in real-time.
To begin, configure your Torque Pro app for data logging and web server upload. Navigate to Settings > Data Logging and Upload within Torque. Ensure that “Upload to web server” is checked. In the “Webserver URL” field, input your Node-RED server address, typically formatted as http://your.nodered.server:1880/torque/. This URL serves as the endpoint for Torque to send your vehicle’s diagnostic data.
Next, import the following Node-RED flow into your Node-RED environment. This flow is designed to receive the data transmitted by Torque Pro via HTTP GET requests and process it for visualization or storage.

designed to:
- Receive HTTP GET requests: The
http innode listens for incoming data from Torque Pro at the/torqueendpoint. - Respond with “OK!”: The
http responsenode sends a confirmation back to Torque Pro, ensuring data transmission is successful. - Process and Display Data: Various
changeandui_gaugenodes extract specific PID (Parameter IDs) from the Torque data, such as RPM, speed, coolant temperature, and more. These values are then displayed on your Node-RED dashboard using gauges and text elements. - Optional Data Storage: The flow includes nodes for storing the raw JSON data into a MySQL database and publishing to an MQTT broker. These can be removed if you only require real-time visualization.
With this setup, you can now monitor your vehicle’s vital signs in real-time through your custom Node-RED dashboard, leveraging the power of OBD2 torque data for insightful diagnostics and performance analysis.
