PZEM-017 v1.0

Arduino communication library for Peacefair PZEM-017 v1.0 Energy monitor, a slightly modify version of Jakub Mandula's PZEM-004T-v30 library (https://github.com/mandulaj/PZEM-004T-v30)

Common issue:

Make sure the device is connected to the 5v power!

Example

#include <PZEM017v1.h>

/* Use software serial for the PZEM
 * Pin 4 Rx (Connects to the Tx pin on the PZEM)
 * Pin 5 Tx (Connects to the Rx pin on the PZEM)
*/
PZEM017v1 pzem(4, 5); //WMOS D1 4=D1, 5=D2

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

void loop() {
    float voltage = pzem.voltage();
    if( !isnan(voltage) ){
        Serial.print("Voltage: "); Serial.print(voltage); Serial.println("V");
    } else {
        Serial.println("Error reading voltage");
    }

    float current = pzem.current();
    if( !isnan(current) ){
        Serial.print("Current: "); Serial.print(current); Serial.println("A");
    } else {
        Serial.println("Error reading current");
    }

    float power = pzem.power();
    if( !isnan(power) ){
        Serial.print("Power: "); Serial.print(power); Serial.println("W");
    } else {
        Serial.println("Error reading power");
    }

    float energy = pzem.energy();
    if( !isnan(energy) ){
        Serial.print("Energy: "); Serial.print(energy,3); Serial.println("kWh");
    } else {
        Serial.println("Error reading energy");
    }

    Serial.println();
    delay(2000);
}

Installation instructions

You should be able to install the library from the Library Manager in the Arduino IDE. You can also download the ZIP of this repository and install it manually. A guide on how to do that is over here: https://www.arduino.cc/en/guide/libraries

Thank you to @olehs and Jakub Mandula for this great library.
