Raspberry Pi MQTT environment for Internet of Thing
In this Project I will show how I have self-hosted an MQTT environment with the help of a mosquitto broker running on a Raspberry Pi and let ESP32 microcontrollers publish sensor data and subscribe to control LED through the broker. these data will be persisted in a Node-RED UI. (Based on the ESP32 MQTT Publish/Subscribe DS18B20 Temperature to Node-Red Video on my channel) and use cpolar enables public network users to access intranet services normally.
the ESP32 code is placed on my blog :
