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.

To integrate MQTT into Home Assistant, add the following section to your configuration.yaml file:

# Example configuration.yaml entry
mqtt:
  broker: IP_ADDRESS

For detailed setup instructions, please refer to the MQTT broker documentation.
