Events: state

The Events: State node listens for state changes of entities within Home Assistant. It triggers a flow in Node-RED whenever an entity's state changes, allowing you to automate responses to various conditions, like turning on lights when motion is detected or sending a notification when a door is opened.

Configuration:

Entity required

Type: string

The entity ID is used to listen for state changes. This can be a entity ID, regex, or a substring. If a regex or substring is used, the node will listen for all entities that match.

Example:

light.kitchen (entity) listens for state changes of the light.kitchen entity
^light.* (regex) listens for state changes of all entities that start with light.
light (substring) listens for state changes of all entities that contain light in the entity ID

If State

Type: string

If the conditional is evaluated as true send the message to the first output otherwise send it to the second output. If blank there will only be one output.
