In this session we will install the Mosquitto Broker for MQTT communication on a Raspberry Pi board.

There are several brokers you can use. In home automation projects, we use the Mosquitto Broker installed on a Raspberry Pi.

MQTT stands for Message Queuing Telemetry Transport. MQTT is a simple messaging protocol, designed for constrained devices with low bandwidth. So, it’s the perfect solution to exchange data between multiple IoT devices.

MQTT communication works as a publish and subscribe system. Devices publish messages on a specific topic. All devices that are subscribed to that topic receive the message.

The MQTT broker is responsible for receiving all messages, filtering the messages, deciding who is interested in them, and then publishing the message to all subscribed clients.
