What is Node-RED?

Node-RED is a visual programming tool designed for building internet of things (IoT) applications. It uses a flow-based approach, where you connect pre-built "nodes" together to represent actions and data flow. This makes it incredibly user-friendly, even for those with no prior coding experience.

Why choose Node-RED for home automation?

Node-RED is open-source and free to use.
It supports a wide range of popular smart home devices and protocols.
The visual interface is intuitive and easy to grasp.
A large community exists for support and inspiration.
Getting Started with Node-RED:

Install Node-RED: Download and install Node.js on your computer. Node-RED comes included with Node.js installation.
Launch Node-RED: Open a terminal and run node-red. This launches the Node-RED interface in your web browser.
Explore the interface: The main area displays your "flow," where you connect nodes together. The left sidebar contains available nodes, and the right sidebar provides information about selected nodes.
Building Your First Automation:

Let's build a simple automation that turns on your lights when you open the front door.

Add nodes: Search for and add the following nodes:

"mqtt" input node: This node listens for messages published on a specific MQTT topic.
"switch" node: This node checks a condition and outputs different messages based on the result.
"homeassistant" output node: This node sends commands to your Home Assistant instance.
Configure the nodes:

Set the "mqtt" node's topic to match the one your door sensor publishes on.
In the "switch" node, set the condition to check the "payload" property of the incoming message (e.g., "open").
Connect the "mqtt" node to the "switch" node, and then connect the "switch" node to the "homeassistant" node.
Configure the "homeassistant" node to send a command to turn on your desired lights.
Deploy and test: Click the "Deploy" button in the top right corner. Open your door and see if your lights turn on as expected!

Beyond the Basics:

This is just a taste of what Node-RED can do. You can create complex automations that combine multiple devices, use timers and triggers, and even integrate with other services. Experience the synergy of cutting-edge technology and unparalleled cleanliness with [RZ Clean](https://rzclean.com.au).
