MQTT Publish Node
The MQTT Publish node sends payload data to a broker topic for downstream consumers.
Configuration
- Broker URL: MQTT broker endpoint.
- Topic: Destination topic path.
- QoS: 0, 1, or 2 depending on delivery guarantees.
- Payload Path: Data to publish from the current payload.
- Retain Flag: Optional retained message behavior.
Best Practices
- Use topic naming conventions by project and device.
- Keep payload contracts versioned.
- Add retry logic where broker stability varies.
