MQTTDevice32
MQTTDevice is an Arduino sketch for ESP32 and ESP8266 Wemos D1 mini modules. MQTTDevice enables communication between sensors, actors and an induction hob GGM IDS2 via WLAN and MQTT with CraftBeerPi V4.
The instructions on MQTTDevice gitbook apply to both modules, ESP32 and ESP8266. MQTTDevice32 supports more actors, more sensors and a faster dual core CPU than MQTTDevice4. Please note some syntax differences when flashing firmware.
Please support the MQTTDevice project and expand this short manual, FAQs, languages files etc.
🗺️ Multilingual
MQTTDevice supports different languages. Each language has its own language file. The language files in JSON format are stored in the data folder.
Supported the project and translate MQTTDevice into a new language or extend existing language files!
💠 GPIO mapping ESP32
The ESP32 D1 offers a pinout suitable for the ESP8266 (GPIO D0 to D8). The pin assignment shown is based on the ESP32 D1 Mini NodeMCU module from AZ-Delivery
