Developing

1. Rename config (TEMPLATE).h to config.hpp with correct settings

2. In main.ino create all devices and add them to device list

3. To use ESP32 with arduino IDE follow this manual: https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html arduino.additionalUrls

   Or use VSCode (recommended for better IntelliSense) with Arduino extension (needs similar config as Arduino IDE)

4. Use ESP32 Dev Module as selected board. Dont forget to set correct COM port.

5. Update c_cpp_properties.json with your path

   "env": {
      "pathToArduino": "your\\path\\to\\arduino",
      "pathToLib": "your\\path\\to\\lib"
   },

6. Install libraries

• ArduinoJson by Benoit Blanchon
• WebSockets by Markus Sattler
• ESP32Servo by John K.
• OneWire by Jim Studt
  • IMPORTANT: to fix 'rtc_gpio_desc' error visit: https://githubmemory.com/repo/PaulStoffregen/OneWire/issues/100 or Find 'rtc_gpio_desc' replace with 'rtc_io_desc' in the 'OneWire_direct_gpio.h' file solved the issue
• ModbusMaster (2.0.1) from https://www.arduino.cc/reference/en/libraries/modbusmaster/
• Arduino-Temperature-Control-Library from https://github.com/milesburton/Arduino-Temperature-Control-Library

Schemas

*With DS18B20 you can add multiple sensors to same pins because OneWire

*With H300 we also had to add 1k resistors between A-VIN and B-GND
