Node-RED<\/strong> Node-RED is a low-code programming platform that lets you create automation and integrations through graphical workflows. Thanks to its intuitive drag-and-drop interface, Node-RED is particularly appreciated in the field of home automation<\/strong> for its simplicity and ease of integration with a wide range of protocols and services.<\/p>\n\n\n\n

In this tutorial, you'll learn how to install Node-RED on your Raspberry Pi and create automations for your home automation system or IoT projects.<\/p>\n\n\n\n

Why use Node-RED for home automation?<\/h3>\n\n\n\n

Node-RED connects peripherals<\/strong> such as sensors, home automation management systems, or web services by creating flows<\/strong> automation. For example, you can use Node-RED to :<\/p>\n\n\n\n

    \n
  • Automate your home's lighting according to the brightness outside.<\/li>\n\n\n\n
  • Receive alerts on your phone when specific events occur.<\/li>\n\n\n\n
  • Control your devices with Home Assistant<\/strong>, Jeedom<\/strong>or Mosquitto MQTT<\/strong> for managing messages between different IoT devices.<\/li>\n<\/ul>\n\n\n\n

    Step 1: Installing Node-RED on Raspberry Pi<\/h3>\n\n\n\n
      \n
    1. Preparing your Raspberry Pi<\/strong> :\n
        \n
      • Make sure that Raspberry Pi OS<\/strong> is installed on your Raspberry Pi. If this is not the case, follow this tutorial to install Raspberry Pi OS Lite<\/strong> with Raspberry Pi Imager<\/strong>.<\/li>\n\n\n\n
      • Connect to the Raspberry Pi via SSH<\/strong> with this command:\n
          \n
        • ssh pi@<IP_de_votre_Raspberry_Pi><\/code><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Install Node-RED<\/strong> Node-RED can be easily installed with a script available on GitHub. Run this command in your SSH terminal:\n
            \n
          • Copy code : bash <(curl -sL https:\/\/raw.githubusercontent.com\/node-red\/linux-installers\/master\/deb\/update-nodejs-and-nodered) <\/code><\/li>\n\n\n\n
          • Validate questions with y<\/code> to authorize the installation of dependencies.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
          • Start Node-RED<\/strong> Once installation is complete, launch Node-RED with :\n
              \n
            • Copy the code : node-red-start <\/code><\/li>\n\n\n\n
            • Node-RED is now active. You can access the interface via a browser by entering the following address:\n
                \n
              • http:\/\/<IP_de_votre_Raspberry_Pi>:1880<\/code><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n\n\n\n
              • Automate Node-RED startup<\/strong> To have Node-RED start automatically each time the Raspberry Pi is booted, activate the service with this command:\n
                  \n
                • sudo systemctl enable nodered.service<\/code><\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

                  Step 2: Create automations with Node-RED<\/h3>\n\n\n\n

                  Example 1: Controlling lights with MQTT<\/h4>\n\n\n\n
                    \n
                  1. Install an MQTT broker such as Mosquitto<\/strong> on your Raspberry Pi.<\/li>\n\n\n\n
                  2. Use MQTT nodes<\/strong> in Node-RED to publish and subscribe to MQTT messages, enabling you to send commands to your connected lights.<\/li>\n<\/ol>\n\n\n\n

                    Example 2: Notification of movement via Telegram<\/h4>\n\n\n\n
                      \n
                    1. Add a motion sensor<\/strong> compatible with your home automation system.<\/li>\n\n\n\n
                    2. Use input nodes<\/strong> to trigger a notification when the sensor detects movement.<\/li>\n\n\n\n
                    3. Add a node Telegram<\/strong> to send a message to your phone.<\/li>\n<\/ol>\n\n\n\n

                      Example 3: Integration with Home Assistant<\/h4>\n\n\n\n

                      Node-RED integrates directly with Home Assistant<\/strong>. You can use it to automate complex tasks such as blind control, temperature management or lighting scenarios. Simply install the Node-RED add-on from the Home Assistant interface.<\/p>\n\n\n\n

                      Conclusion<\/h3>\n\n\n\n

                      Node-RED<\/strong> is a powerful and flexible tool for home automation and IoT projects. Whether you're a beginner or an expert, you can quickly create complex workflows without writing code. With integrations for MQTT<\/strong>, Home Assistant<\/strong>and other services, Node-RED is the ideal platform for managing your connected systems.<\/p>","protected":false},"excerpt":{"rendered":"
