Multiple ESP32 WiFi (Free MQTT Broker)
In this video, I'll show you how to communicate between different ESP32s using a free public broker that allows us to connect from any internet network. This project uses an SSD1306 OLED display to monitor the variables published to MQTT topics from two ESP32s. I hope you enjoy the video.
