Exposed Nodes

Nodes Available for Exposure

The following nodes can be exposed to Home Assistant, appearing as switches that can be toggled to enable or disable them in Node-RED:

• Device
• Events: all
• Events: state
• Poll State
• Sentence
• Tag
• Time
• Trigger: state
• Webhook
• Zone

This feature provides a cleaner alternative to creating input_booleans in Home Assistant for controlling flow activation.

Triggering Exposed Nodes via nodered.trigger

Exposed nodes can be activated using the nodered.trigger service call with the following parameters:

entity_id

• Required
• The entity_id of the exposed node to be triggered, as seen in Home Assistant. For example, use switch.my_node if that is the node's entity_id.

output_path

• Optional
• Default: 0
• Can be a comma-separated list of output paths.
• Determines which output path(s) the message will be sent through:
  • 0: Send through all output paths.
  • 1: Send through the first output path.
  • 2: Send through the second output path, and so on.

message

• Required
• The message to be sent when triggering the node. This should be a valid JSON object. For example, { "payload": "hello world" } would set msg.payload to hello world.
