Arduino IDE can not compile the sketch. #51

Hi. After installing esp32 in arduino IDE using the updated method ( not the old git method), the pzem-004t sketches can not be compiled. It worked before when i was using the old method to install esp32 in arduino IDE. This is the error:

Arduino: 1.8.3 (Windows 10), Board: "ESP32 Dev Module, Disabled, Default, QIO, 80MHz, 4MB (32Mb), 921600, None"

Can you try renaming serial port variable to smth like PzemSerial instead of Serial2 ?
