@thrasher Sorry for my bad writing.
So I want to use 2 piece of PZEM for my project and I test PZEM that connect to UART2 it can send value to monitor with speed 115200 and then I test to PZEM that connect to UART0 it not show any value excpet "NaN" from my monitor. how can I fix this?

I use PZEM V4.0 for my project, so I want to use it for 2 and I connect to TXRXD0,TXRXD2 and this is my code.

#include <PZEM004Tv30.h>

PZEM004Tv30 pzem(&Serial);
PZEM004Tv30 pzem2(&Serial2);

void setup() {
  Serial.begin(115200);

  Serial.print("Reset Energy");
  pzem.resetEnergy();
  pzem2.resetEnergy();

  Serial.print("Set address to 0x42");
  pzem.setAddress(0x42);
  pzem2.setAddress(0x42);
}

void loop() {

  float cur = pzem.current();
  Serial.print("Current: ");
  Serial.print(cur);
  Serial.println("A");

  float cur2 = pzem2.current();
  Serial.print("Current 2: ");
  Serial.print(cur2);
  Serial.println("A");

  delay(1000);
}

The result is not showing the value of UART0 (pin GPIO1,3).
How can I fix this?
