How to Install Mosquitto MQTT Broker on Raspberry Pi & Connect ESP32
In this video, I show you how to turn your Raspberry Pi into a local IoT server using the Mosquitto MQTT Broker. We will go step-by-step from installation to controlling an ESP32 over your local network without relying on any cloud services.
*💡 What you will learn:*
Setting up a local MQTT Broker on Raspberry Pi
Understanding Publisher vs Subscriber concepts
Sending data between ESP32 and Raspberry Pi
Controlling hardware over Wi-Fi without the Cloud
