# Node-RED

Node-RED is an **open-source, flow-based tool** that lets you connect devices, APIs, and services with a simple drag-and-drop interface. It’s widely used for **home automation, IoT projects, data processing, and dashboards**, making it easy to integrate hardware and software without heavy coding.

This add-on is optional and not installed by default. To use it, go to the **Add-On** section and click **Install** to set up the service.
