Control ESP32 GPIO via Webhook and MQTT in n8n - n8n Workflow | Neura Market

    Control ESP32 GPIO via Webhook and MQTT in n8n

    This workflow allows you to control an ESP32 microcontroller's GPIO pins using a simple web interface, webhook, and MQTT protocol in n8n.

    The workflow demonstrates how to set up a control system for an ESP32 microcontroller using n8n, a webhook, and MQTT. A webpage with on/off buttons sends a value via a webhook to trigger the workflow. The workflow processes this value and publishes it to an MQTT broker, which the ESP32 subscribes to, toggling its GPIO pins accordingly. This setup is ideal for IoT applications where remote control of devices is required.
