Rule Nodes

Rule Nodes are the building blocks of Rule Chains. Each node processes one incoming message at a time and routes the result to connected nodes via named relations (Success, Failure, True, False, or custom names).

Nodes fall into seven categories:

• 

  Filter

  Route messages based on conditions — no data modification

• 

  Enrichment

  Add attributes, telemetry, or entity details to message metadata

• 

  Transformation

  Modify payload, metadata, type, or originator

• 

  Action

  Perform system operations — persist data, manage alarms, send RPC

• 

  External

  Publish data to external systems (Kafka, MQTT, REST, cloud, email)

• 

  Flow

  Control routing between rule chains and queues

• 

  PE only

  Analytics

  Aggregate data streams and compute statistics
