Node-RED is preinstalled on the Aragon Master. Node-RED hosts a central part of the home automation logics. Node-RED is also available for users to add their specific logics. Users can download useful and interesting Node-RED flows from our Node-RED library for Aragon2.
Browser-based flow editing
Node-RED provides a browser-based flow editor that makes it easy to wire together flows using the wide range of nodes in the palette. Flows can be then deployed to the runtime in a single-click.
JavaScript functions can be created within the editor using a rich text editor.
A built-in library allows you to save useful functions, templates or flows for re-use.
Social Development
The flows created in Node-RED are stored using JSON which can be easily imported and exported for sharing with others.
An online flow library allows you to share your best flows with the world.

Q: What are the advantages to use on-device installation of Node-RED for home automation compared to a cloud based solution like IFTTT ?
Answer:
1. Security & Privacy: On-device installation of Node-RED offers a much higher level of security and privacy compared to a cloud based solution like IFTTT as all the data remains securely stored locally within the user’s home network.
2. Customization: On-device installation of Node-RED provides a much higher level of customization compared to a cloud based solution like IFTTT as users can tailor the automation to their exact needs.
3. Cost: On-device installation of Node-RED is significantly more cost effective compared to a cloud based solution like IFTTT as users do not have to pay any subscription fees.
4. Reliability: On-device installation of Node-RED is more reliable compared to a cloud based solution like IFTTT as users are not reliant on an external service to provide the automation services.
