mqtt_statestream integration publishes state changes in Home Assistant to individual MQTT topics.
To enable MQTT Statestream in Home Assistant, add the following section to your
# Example configuration.yaml entry mqtt_statestream: base_topic: homeassistant publish_attributes: true publish_timestamps: true
(string)(Required)Base topic used to generate the actual topic used to publish.
(boolean)(Optional)Publish attributes of the entity as well as the state.
Default value: false
(boolean)(Optional)Publish the last_changed and last_updated timestamps for the entity.
Default value: false
(list)(Optional)Configure which integrations should be excluded from recordings. See *Include/Exclude* section below for details.
(list)(Optional)Configure which integrations should be included in recordings. If set, all other entities will not be recorded.
When any Home Assistant entity changes, this integration will publish that change to MQTT.
The topic for each entity is different, so you can easily subscribe other systems to just the entities you are interested in.
The topic will be in the form
For example, with the example configuration above, if an entity called ‘light.master_bedroom_dimmer’ is turned on, this integration will publish
If that entity also has an attribute called
brightness, the integration will also publish the value of that attribute to
All states and attributes are passed through JSON serialization before publishing. Please note that this causes strings to be quoted (e.g., the string ‘on’ will be published as ‘“on”’). You can access the JSON deserialized values (as well as unquoted strings) at many places by using
value_json instead of
The last_updated and last_changed values for the entity will be published to
homeassistant/light/master_bedroom_dimmer/last_changed, respectively. The timestamps are in ISO 8601 format - for example,
The exclude and include configuration variables can be used to filter the items that are published to MQTT.
1. If neither exclude or include are specified, all entities are published.
2. If only exclude is specified, then all entities except the ones listed are published.
# Example of excluding entities mqtt_statestream: base_topic: homeassistant exclude: domains: - switch entities: - sensor.nopublish
In the above example, all entities except for switch.x and sensor.nopublish will be published to MQTT.
3. If only include is specified, then only the specified entries are published.
# Example of excluding entities mqtt_statestream: base_topic: homeassistant include: domains: - sensor entities: - lock.important
In this example, only sensor.x and lock.important will be published.
4. If both include and exclude are specified then all entities specified by include are published except for the ones specified by exclude.
# Example of excluding entities mqtt_statestream: base_topic: homeassistant include: domains: - sensor exclude: entities: - sensor.noshow
In this example, all sensors except for sensor.noshow will be published.
