Action Nodes
Learn about action nodes that perform operations like sending messages and notifications.
Action nodes perform operations that affect the outside world — sending messages, triggering notifications, or calling external services.
Overview
Action nodes are typically placed at the end of a workflow, after data has been processed. They execute an action based on the workflow's results.
Available Actions
| Action | Description |
|---|---|
| MQTT Publish | Publish a message to an MQTT topic |
| MQTT Publish Custom | Publish a message with custom MQTT settings |
| Notification | Send a notification alert |
Using Action Nodes
Action nodes receive data from previous nodes and use it to perform their operation:
- Configure the action settings (topic, message format, recipients)
- Map variables from previous nodes to the action parameters
- Execute when the workflow runs
Best Practices
- Always test actions with sample data before deploying
- Use descriptive message formats that include context
- Consider rate limits when sending frequent notifications
- Log action results for debugging and monitoring
