About this video

Node Red has quite rightly generated a huge head of steam in the 3 years since IBM released it as an Open Source project. Here I quickly review the interface and short circuit some of the installation and upgrade problems. If you need a reason to learn OO JavaScript then this too is an excellent starting point.

Related article summary

Node-RED, developed by IBM, is a browser-based visual flow editor for IoT and home automation that integrates well with Home Assistant. The article explains Node-RED features, compatible hardware, and contrasts it with Home Assistant YAML automations. It provides two detailed projects: a Raspberry Pi Node-RED UI-driven home automation and a standalone Pi + Sonoff/ESP8266 + MQTT system (with Sonoff-Tasmota flashing, Mosquitto MQTT setup, Node-RED dashboard, security, and expansion ideas). Step-by-step installation, wiring, Node.js/npm fixes, MQTT testing, dashboard setup, Sonoff programming, and securing the broker are covered.
