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, you need to setup the MQTT integration.

You will also need to setup an MQTT broker, please refer to the MQTT broker documentation.
