Revolution Pi Node-RED Checklist:

Image Types:

  1. Image Types: There are two image types for Revolution Pi devices: Full Image and Lite Image.

    • When using the Full Image, Node-RED is pre-installed. For instructions on starting Node-RED and creating your first flow, refer to the Node-RED Tutorial.

    • If you are using the Lite Image, Node-RED installation must be done manually. Instructions for manual installation can be found here.

    • All RevPi images can be found here.

After manually installing Node-RED using the Lite Image, you won't be able to start Node-RED via Pictory. Instead, you can access it through a web browser using the IP address of your RevPi, followed by port 1880. For example: http://192.168.1.xxx:1880.

To start Node-RED and configure it as a boot application, follow these commands on the command line:

#start node-red node-red-start # Start Node-RED on boot sudo systemctl enable nodered.service

Node-RED Components:

  1. Node-RED Components: Node-RED consists of several components. It operates as a third-party system on our platform. If you have any questions, please feel free to post them in our forum. There is a dedicated Node-RED category for this purpose.

Node.js:

  1. Node.js: Ensure you have Node.js installed.

    • To install or update Node.js, visit the official Node.js download page.
