MQTT


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.

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:

# Example configuration.yaml entry
mqtt:

To connect to your own MQTT broker:

# Example configuration.yaml entry
mqtt:
  broker: IP_ADDRESS_BROKER

The minimal setup uses the embedded MQTT broker, however a separate broker is advised for more stability.
