You can also run Mosquitto MQTT broker on the cloud. ESP8266 NodeMCU MQTT – Publish DS18B20 Temperature Readings (Arduino IDE).ESP32 MQTT – Publish DS18B20 Temperature Readings (Arduino IDE).ESP8266 and Node-RED with MQTT (Publish and Subscribe).ESP32 MQTT – Publish and Subscribe with Arduino IDE.We have several MQTT practical examples that you can experiment with. Now, you can experiment with MQTT in your ESP32/ESP8266 IoT projects. In this tutorial, you checked that your Mosquitto Broker installed on the Raspberry Pi is running properly. This simple example shows how MQTT works and how your devices (for example: ESP8266 or ESP32, etc.) can be subscribed to the same topic to receive messages, or a device can publish messages to multiple devices. Since two clients are subscribed to testTopic topic, they will both receive the “Hello world!” message. ![]()
