 An ESP8266 is actually not sufficient, because Modbus communication works fail-free only with hardwareserial. ESP8266 has only one Hardwareserial port which is used by serial/debug output. ESP32 has 3 Hardewareserial ports and we use one of them. Another reason is available memory for such huge json definition or such large modbus answers.
