Imagine your smart home devices talking directly to each other, no cloud, no delays, just instant communication. That’s exactly what MQTT does!

MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol designed for smart home automation.

With MQTT running in Home Assistant, your sensors, switches, and smart devices all work together seamlessly, even without an internet connection.
