### Embedded broker (Deprecated)
|
||||
|
||||
Home Assistant contains an embedded MQTT broker called [HBMQTT](https://pypi.python.org/pypi/hbmqtt). If you don't have an MQTT broker, you can configure this one to be used. If configured, Home Assistant will automatically connect to it.
|

As of release 0.92, the embedded broker has been marked as deprecated. This means bugs may not be fixed, and the functionality may be removed in a future release.

There is [an issue](https://github.com/beerfactory/hbmqtt/issues/62) with the HBMQTT broker and the WebSocket connection that is causing a memory leak. If you experience this issue, consider using another broker like Mosquitto.

#### Owntracks
|
||||
|
||||
To use Owntracks with the internal broker a small configuration change must be made in order for the app to use MQTT protocol 3.1.1 (Protocol Level 4).
|
||||
|
||||
In the Owntracks preferences (Android: v1.2.3+, iOS: v9.5.1+) open **Configuration Management**; Find the value named `mqttProtocolLevel` and set the value to `4`. The application will now use MQTT 3.1.1 to connect, which is compatible with the embedded broker.
|
||||
|
||||
#### Settings
|
||||
|
||||
If you want to customize the settings of the embedded broker, use `embedded:` and the values shown in the [HBMQTT Broker configuration](http://hbmqtt.readthedocs.org/en/latest/references/broker.html#broker-configuration). This will replace the default configuration.
|
||||
|
||||
```yaml

embedded:

The [embedded MQTT broker](/docs/mqtt/broker#embedded-broker) does not save any messages between restarts. If you use the embedded MQTT broker you have to send the MQTT discovery messages after every Home Assistant restart for the devices to show up.

The simplest but not the coolest way as a human to interact with a Home Assistant sensor is launching a command manually. Let's create a "Mood" sensor. For simplicity Home Assistant and the MQTT broker are both running on the same host. The needed configuration snipplets to add to the `configuration.yaml` file consists of two parts: one for the broker and one for the sensor.

Party people, 0.16 is here! The big thing with this release is that we have completely removed the barrier to get started by MQTT by being able to launch an embedded MQTT server: [hbMQTT]. Just add `mqtt:` to your config and a broker is launched and connected with Home Assistant. See the [documentation][embedded server] for more info.

Download the [sample script](https://github.com/home-assistant/home-assistant-dev-helper/blob/master/ha-mqtt-demo.py). It depends on [paho-mqtt](https://pypi.python.org/pypi/paho-mqtt). If you run the script inside your [Home Assistant's virtual environment](/docs/installation/virtualenv/) then you are good to go as the dependency should be present if you have used MQTT before. Otherwise, install it with `$ pip3 install paho-mqtt`. The same applies to the embedded broker.
