Paho MQTT
The Paho component enables integration of applications with the MQTT protocol, facilitating communication between devices and systems in Internet of Things (IoT) environments.
Important notes:
- Supports connection to external MQTT brokers to publish messages and subscribe to topics.
- Integrations cannot be used as an MQTT broker (only as a client).
- Compatible with MQTT protocol versions 3.1.1 and 3.1.
URI Syntax: paho:topic
Main Fields
Path parameters
Query parameters
Example
The following flow publishes a message to a topic on an external broker without authentication and without using TLS through Integrations. The published message will be the payload sent to a REST endpoint.
The flow starts with a POST request to the /mqtt-01 endpoint with content in the body.
Then, it publishes to the MQTT broker:
- Topic:
sensedia-01 - Broker:
test.mosquitto.orgon port1883(TCP protocol without encryption) - No authentication (public test broker)
- The body content is published as a message to the topic.
