IoT Device Control via MQTT and Webhook - n8n Workflow | Neura Market

    IoT Device Control via MQTT and Webhook

    Control IoT devices like ESP32 remotely using a webpage with on/off buttons that trigger n8n webhook, MQTT publish, and GPIO toggle.

    This n8n workflow demonstrates practical IoT control using MQTT protocol. A simple HTML webpage presents 'on' and 'off' buttons. Clicking a button sends the value via webhook to n8n (e.g., http://localhost:5678/webhook/pin-control?value=on). The workflow's Set node formats the payload, then the MQTT node publishes it to a cloud broker on a specified topic. A remote ESP32 microcontroller subscribes to the broker, reads the payload, and toggles GPIO2 accordingly—turning an LED on for 'on' or off
