Help me combine the coding

Need Help With My Project

Coding for Arduino UNO (Measuring current using acs712 20A current sensor)

int mVperAmp = 100; // use 185 for 5A, 100 for 20A Module and 66 for 30A Module
double Voltage = 0;
double VRMS = 0;
double AmpsRMS = 0;

void setup(){
pinMode(A0, INPUT);
Serial.begin(9600);
delay(10);
Serial.println(F("Init...."));
}

void loop(){
Voltage = getVPP();
VRMS = (Voltage/2.0) *0.707; // sq root
AmpsRMS = (VRMS * 1000)/mVperAmp;
float Wattage = (220*AmpsRMS)-20; //Observed 18-20 Watt when no load was connected, so substracting offset value to get real consumption.
Serial.print(AmpsRMS);
Serial.println(" Amps RMS ");
Serial.print(Wattage);
Serial.println(" Watt ");
Serial.println("");
}

float getVPP()
{
float result;

int readValue; //value read from the sensor
int maxValue = 0; // store max value here
int minValue = 1024; // store min value here

uint32_t start_time = millis();

while((millis()-start_time) < 1000) //sample for 1 Sec
{
readValue = analogRead(sensorIn);
// see if you have a new maxValue
if (readValue > maxValue)
{
/*record the maximum sensor value*/
maxValue = readValue;
}
if (readValue < minValue)
{
/*record the maximum sensor value*/
minValue = readValue;
}
}

// Subtract min from max
result = ((maxValue - minValue) * 5)/1024.0;

return result;
}

Coding for nodemcu (Controlling relay)

#define BLYNK_PRINT Serial
#include<ESP8266WiFi.h>
#include<BlynkSimpleEsp8266.h>
char auth[] = "IoeQOU61afoVkwUrFHoQKZ4hHmWSYMz6";
char ssid[] = "SIANTAN@unifi";
char pass[] = "JRT25623";

BLYNK_WRITE(V0)
{
  if (param.asInt()) {
    digitalWrite(16, HIGH);
  } else {
    digitalWrite(16, LOW);
  }
}
BLYNK_WRITE(V1) {
  if (param.asInt()) {
    digitalWrite(5, HIGH);
  } else {
    digitalWrite(5, LOW);
  }
}
BLYNK_WRITE(V2) {
  if (param.asInt()) {
    digitalWrite(4, HIGH);
  } else {
    digitalWrite(4, LOW);
  }
}

void setup()
{
pinMode(A0, INPUT);
Serial.begin(9600);
delay(10);
Serial.println(F("Init...."));
Blynk.begin(auth,ssid,pass);{
}
pinMode(16,OUTPUT);
pinMode(5,OUTPUT);
pinMode(4,OUTPUT);
}
void loop()
{
  Blynk.run();
}

Combine both coding

#define BLYNK_PRINT Serial
#include<ESP8266WiFi.h>
#include<BlynkSimpleEsp8266.h>
char auth[]="IoeQOU61afoVkwUrFHoQKZ4hHmWSYMz6";
char ssid[]="SIANTAN@unifi";
char pass[]="JRT25623";
const int sensorIn = A0;
int mVperAmp = 100; // use 185 for 5A, 100 for 20A Module and 66 for 30A Module
double Voltage = 0;
double VRMS = 0;
double AmpsRMS = 0;


BLYNK_WRITE(V0)
{
if (param.asInt()) {
digitalWrite(16, LOW);
} else {
digitalWrite(16, HIGH);
}
}
BLYNK_WRITE(V1){
if (param.asInt()) {
digitalWrite(5, LOW);
} else {
digitalWrite(5, HIGH);
}
}
BLYNK_WRITE(V2){
if (param.asInt()) {
digitalWrite(4, LOW);
} else {
digitalWrite(4, HIGH);
}
}

void setup()
{
{
pinMode(A0, INPUT);
Serial.begin(9600);
delay(10);
Serial.println(F("Init...."));
}
 Serial.begin(9600);
  Blynk.begin(auth,ssid,pass);
pinMode(16,OUTPUT);
pinMode(5,OUTPUT);
pinMode(4,OUTPUT);
}

void loop(){
Voltage = getVPP();
VRMS = (Voltage/2.0) *0.707; // sq root
AmpsRMS = (VRMS * 1000)/mVperAmp;
float Wattage = (220*AmpsRMS)-20; //Observed 18-20 Watt when no load was connected, so substracting offset value to get real consumption.
Serial.print(AmpsRMS);
Serial.println(" Amps RMS ");
Serial.print(Wattage);
Serial.println(" Watt ");
Serial.println("");
}

float getVPP()
{
float result;

int readValue; //value read from the sensor
int maxValue = 0; // store max value here
int minValue = 1024; // store min value here

uint32_t start_time = millis();

while((millis()-start_time) < 1000) //sample for 1 Sec
{
readValue = analogRead(sensorIn);
// see if you have a new maxValue
if (readValue > maxValue)
{
/*record the maximum sensor value*/
maxValue = readValue;
}
if (readValue < minValue)
{
/*record the maximum sensor value*/
minValue = readValue;
}
}

// Subtract min from max
result = ((maxValue - minValue) * 5)/1024.0;

return result;
Blynk.run();
}

After combined both codings, I can get the reading of measured current from the current sensor(acs712 20A) but can not control the relay throught blynk. Anyone can help to notice my mistake on combining both of the code.Thank you

I’ve removed your unformatted code, as your post was unreadable, and anyone attempting to help you would find that copying your unformatted code would prevent it from compiling because characters like quotation marks are corrupted by the forum when code is posted like this.

Please use the pencil icon at the bottom of your gfirst post to edit the post and put your code back in - this time with tripple backticks at the begining and end of each of the two sections of code.
Triple backticks look like this:
```

Also, you’re unlikely to get anyone to help unless you explain what it is that the two pieces of code are supposed to do, and what it is that you want the combined piece of code to do, and which type of device (Arduino or NodeMCU) it is meant to run on.
Information about what each of the widgets in your project are for would also help.

Pete.
