The `mqtt_eventstream` component connects two Home Assistant instances via MQTT.
|
|
|
|
## {% linkable_title Configuration %}
|
|
|
|
To integrate MQTT Eventstream into Home Assistant, add the following section to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
mqtt_eventstream:
|
|
publish_topic: MyServerName
|
|
subscribe_topic: OtherHaServerName
|
|
```
|
|
|
|
{% configuration %}
|
|
publish_topic:
|
|
description: Topic for publishing local events.
|
|
required: false
|
|
type: string
|
|
subscribe_topic:
|
|
description: Topic to receive events from the remote server.
|
|
required: false
|
|
type: string
|
|
ignore_event:
|
|
description: Ignore sending these [events](/docs/configuration/events/) over mqtt.
|
|
required: false
|
|
type: list
|
|
{% endconfiguration %}
|
|
|
|
## {% linkable_title Multiple Instances %}
|
|
|
|
Events from multiple instances can be aggregated to a single master instance by subscribing to a wildcard topic from the master instance.
|
|
|
|
```yaml
|
|
# Example master instance configuration.yaml entry
|
|
mqtt_eventstream:
|
|
publish_topic: master/topic
|
|
subscribe_topic: slaves/#
|
|
ignore_event:
|
|
- call_service
|
|
- state_changed
|
|
```
|
|
|
|
For a multiple instance setup, each slave would publish to their own topic.
|
|
|
|
```yaml
|
|
# Example slave instance configuration.yaml entry
|
|
mqtt_eventstream:
|
|
publish_topic: slaves/upstairs
|
|
subscribe_topic: master/topic
|
|
```
|
|
|
|
```yaml
|
|
# Example slave instance configuration.yaml entry
|
|
mqtt_eventstream:
|
|
publish_topic: slaves/downstairs
|
|
subscribe_topic: master/topic
|
|
```
