MQTT Eventstream

The mqtt_eventstream integration connects two Home Assistant instances via MQTT.

# Example configuration.yaml entry
mqtt_eventstream:
  publish_topic: MyServerName
  subscribe_topic: OtherHaServerName

Configuration Variables

Looking for your configuration file?
publish_topic string (Optional)

Topic for publishing local events.

subscribe_topic string (Optional)

Topic to receive events from the remote server.

ignore_event list (Optional)

List of events which will not be sent over mqtt.

Multiple Instances

Events from multiple instances can be aggregated to a single parent instance by subscribing to a wildcard topic from the parent instance.

# Example parent instance configuration.yaml entry
mqtt_eventstream:
  publish_topic: parent/topic
  subscribe_topic: child/#
  ignore_event:
    - call_service
    - state_changed

For a multiple instance setup, each child instance would publish to their own topic.

# Example child instance configuration.yaml entry
mqtt_eventstream:
  publish_topic: child/upstairs
  subscribe_topic: parent/topic

# Example child instance configuration.yaml entry
mqtt_eventstream:
  publish_topic: child/downstairs
  subscribe_topic: parent/topic
