An external broker is more stable, this is something I did not know as a beginner. Especially because the embedded broker has a memory leak. It would have saved me a bunch of time and WAF trust issues if I would have had this piece of knowledge. Issue on memory leak: https://github.com/home-assistant/home-assistant/issues/11594

MQTT (aka MQ Telemetry Transport) is a machine-to-machine or "Internet of Things" connectivity protocol on top of TCP/IP. It allows extremely lightweight publish/subscribe messaging transport.
|
|
|
|
Your first step to get MQTT and Home Assistant working is to choose a [broker](/docs/mqtt/broker).
|
|
|
|
To integrate MQTT into Home Assistant, add the following section to your `configuration.yaml` file. Keep in mind that the minimal setup will run with [an embedded MQTT broker](/docs/mqtt/broker#embedded-broker):
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
mqtt:
|
|
```
|
|
|
|
To connect to your [own MQTT broker](/docs/mqtt/broker#run-your-own):
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
mqtt:
|
|
broker: IP_ADDRESS_BROKER
|
|
```
|
|
|
|
<p class='note'>
|
|
The minimal setup uses the embedded MQTT broker, however a separate broker is advised for more stability.
