ESP32 MQTT Publish Multiple Sensor Readings to NodeRed
1. Introduction - Currently, there are many IoT protocols such as: CoAP, MQTT, AMQP,. In this tutorial, I will introduce MQTT, one of the famous IoT protocols. This protocol is to control and transfer data between devices in an IoT network Note: for MQTTS please refer Demo 30: How to use Arduino ESP32 MQTTS with MQTTS Mosquitto broker (TLS/SSL).

ESP32 MQTT Tutorial This is a tutorial for getting an ESP32 set up as an Amazon IoT device using MQTT to communicate. Install Arduino IDE No matter what your platform is, you'll need the Ardiuno IDE installed. It can be installed on many platforms including Linux, Windows and MAC. Install ESP32 Support
MQTT Set up MQTT Client to Communicate with Broker Realtek IoT/Wi
Step 1 - Arduino IDE - Add ESP32 to the Board Manager. The Arduino IDE does not know about the ESP32 so the very first step we need to do leverage the the Arduino IDE's 'Board Manager' capability to provide support for the ESP32. In the Arduino IDE, open 'Preferences' and enter in one of the following URL's.

ESP32 MQTT Publish Subscribe with Arduino IDE Random Nerd Tutorials
In this ESP32 tutorial, we will learn to use ESP32 MQTT as a Publisher and Subscriber using Arduino IDE. There will be one ESP32 MQTT publisher and two subscribers. We will publish DHT11 and DHT22 sensor readings to MQTT with ESP32 and one ESP32 will act as a subscriber and Node-Red Dashboard will also subscribe to the MQTT topics and display.
