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.
|
|
|
|
To connect to your [own MQTT broker](/docs/mqtt/broker#run-your-own):
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
mqtt:
|
|
broker: IP_ADDRESS_BROKER
|
|
```
|
|
|
|
You can also use the [embedded MQTT broker](/docs/mqtt/broker#embedded-broker). A separate broker is advised for more stability.
|
|
|
|
<div class='note warning'>
|
|
As of release 0.92, the embedded broker has been marked as deprecated. This means bugs may not be fixed, and the broker functionality will be removed in a future release.
|
|
</div>
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
mqtt:
|
|
password: hello
|
|
```
|
|
|
|
This allows you to connect to the MQTT broker with user `homeassistant` and password `hello`.
