There are several brokers you can use. Mosquitto is an Open Source MQTT (Broker) server that can be installed on a Raspberry Pi (but also on other platforms) to facilitate communication between connected objects (M2M). Mosquitto is an ideal tool for integrating objects connected to a home automation server such as Jeedom, openHAB, Domoticz or Home Assistant. The Raspberry Pi will be acting as the MQTT broker, and the Python client will be run from a separate desktop computer (optional, as this could be run on the Raspberry Pi). To follow along with this Instructable, you will need to have some basic knowledge of electronics, and how to use the Arduino software. The broker’s main responsibilities include collecting all messages, screening them, determining who is interested in them, and sending the messages to all subscribers. You have the choice of using multiple brokers. You might, for example, use a Mosquitto broker running on a Raspberry Pi or a cloud MQTT broker.

How to use MQTT protocol with ESP8266 12E Electronics

Once the MQTT Broker has received the message, it will send it to any devices (in this case, Device #2) which are subscribed to the same topic. In this project, we will be publishing to a topic using an ESP8266, and creating a Python script that will subscribe to this same topic, via a Raspberry Pi which will act as the MQTT Broker. This article covers setting up an MQTT broker on a headless Raspberry Pi 4. Because of the way it is spelled, some people refer to MQTT as “Mosquitto.” If you’d like to know how I setup the headless image for testing, I’ve provided some links at the end of this article. The image I’ve setup has ssh enabled so I can remotely log into it.
