Witam !!
Pobrałem bibliotekę WebServer_WT32  Płytkie ustawiłem na WT32-ETHO1
Próbowałem też a płytką ESP32 DEV Module
Arduino 1.8.19
Mama problem z kompilacja Błąd poniżej

\Arduino\libraries\WebServer_WT32_ETH01\src/WebServer_WT32_ETH01.h:63:4: error: #error This code is designed to run on ESP32 platform! Please check your Tools->Board setting.

  ModbusTCP Server with 4 coils
  Using WT32-ETH01 Board

  Library modbus: ArduinoModbus
  Library for ethernet connection: https://github.com/khoih-prog/WebServer_WT32_ETH01
  Use Arduino Library Manager Installation:
      The best and easiest way is to use Arduino Library Manager. Search for WebServer_WT32_ETH01,
      then select / install the latest version
