This project demonstrates how to use an ESP32 microcontroller to monitor soil moisture levels and communicate the data via MQTT to a broker. The project also includes an RGB LED for visual feedback ...

ArduinoHA allows to integrate an Arduino/ESP based device with Home Assistant using MQTT. The library is designed to use as low resources (RAM/flash) as possible. Initially, it was optimized to work ...

Makers, developers, and hobbyists who enjoy creating projects using the Arduino platform may be excited to learn that Adafruit has recently announced that their MQTT Arduino Library now supports the ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

Last time on Minimal MQTT, we used a Raspberry Pi to set up an MQTT broker — the central hub of a home data network. Now it’s time to add some sensor and display nodes and get this thing running. So ...

Despite its small form factor, the Raspberry Pi is a highly capable system you can grab for well under $100. Depending on your interests, it can double as anything between an emulation system, stream ...
