Application Note

This application note provides a practical guide to integrating Senquip devices with third-party MQTT endpoints. It demonstrates how to verify MQTT connectivity using public test brokers, configure publish and subscribe operations, and implement secure Transport Layer Security (TLS). The document also explains the architectural implications of mutual TLS (mTLS), including per-device certificate provisioning, trust configuration, and lifecycle management. These considerations are essential when connecting devices directly to external MQTT infrastructures. For many deployments, centralising security and certificate management via the Senquip Portal and accessing data through the Senquip API can significantly reduce operational complexity.
