MQTTDevice32 is an Arduino sketch for the ESP32 Wemos D1 mini modules. MMQTTDevice32 enables sensors, actors and an induction hob GGM IDS2 to be communicate via WLAN and MQTT with CraftBeerPi V4. MQTTDevice32 supports more actors and sensors with a faster dual core CPU than MQTTDevice4.
- Web Interface (WebIf) for easy configuration, backup and restore
- Server Sent Events (SSE) for WebClients
- Temperature sensors
- Dallas DS18B20 Sensors (digital)
- Search for connected sensors based on OneWire addresses
- PT100 and PT1000 sensors (analog)
- MAX31865 Amplifyer
- MQTTDevice32 supports max 6 sensors
- MQTTDevice4 supports max 3 sensors
- Dallas DS18B20 Sensors (digital)
- Actors (max 15)
- GPIO selection
- used GPIOs are hidden
- inverted GPIO
- PWM values between 0 and 100% are sent. MQTTDevice "pulses" with a cycle of 1000ms
- MQTTDevice32 supports up to 15 actors
- MQTTDevice4 supports 10 actors
- Induction hob
- induction hob GGM IDS2 can be controlled directly
- Nextion HMI Touchdisplay support
- Audio signals Piezo Buzzer
- WebUpdate firmware
- mDNS support
- Event handling
- File explorer
- support for different languages
A detailed MQTTDevice documentation is available on gitbook: documentation
- Download Firmeware.zip
- unzip Firmware.zip
- edit Flashen.cmd:
- change "COM3" in line 6 und line 8 "esptool.exe -p COM3" as you need
- open command line (cmd.exe) and change into firmware.zip directory
- start script "flashen.cmd"
Script flashen.cmd use esptool.
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!
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
