Technical Implementation Made Simple

n8n's MQTT integration operates through a straightforward mechanism:

1. Connect: Configure the MQTT node with your broker's URL, port, and authentication credentials
2. Subscribe: Listen to specific topics where devices publish their data
3. Process: Transform incoming data using n8n's powerful workflow tools
4. Publish: Send commands back to devices or forward processed data to other systems

The integration supports QoS levels, retained messages, and secure connections via TLS, giving you complete control over your messaging infrastructure. By combining MQTT's efficient publish-subscribe model with n8n's extensive integration capabilities, you can create sophisticated IoT workflows that respond intelligently to real-world events.
