Packet too big when pressing the button

Hey guys I need help for my project. Sending sensor value is working well, but when I pressing the button for my relay on the Blynk app it keep saying “packet too big” and keep disconnecting from blynk. This is the notice :

[18819] Ready (ping: 11ms).
[77626] Ready (ping: 1722ms).
[77666] Packet too big: 47918

And here is my sketch :

  #define BLYNK_PRINT Serial    // Comment this out to disable prints and save space
  #include <ESP8266_Lib.h>
  #include <BlynkSimpleShieldEsp8266.h>
  
  // You should get Auth Token in the Blynk App.
  // Go to the Project Settings (nut icon).
  char auth[] = "*********";
  
  // Your WiFi credentials.
  // Set password to "" for open networks.
  char ssid[] = "*********";
  char pass[] = "*********";
  
  // Hardware Serial on Mega, Leonardo, Micro...
  //#define EspSerial Serial1
  
  // or Software Serial on Uno, Nano...
  #include <SoftwareSerial.h>
  SoftwareSerial EspSerial(8, 9); // RX, TX
  
  // Your ESP8266 baud rate:
  #define ESP8266_BAUD 19200
  
  ESP8266 wifi(&EspSerial);
  
  //Setup relay
  int pengurasPin = 3;
  int pengisiPin = 4;
  int katapangPin = 5;
  
  //Setup Sensor Turbidity
  int sensorValue = analogRead(A0);
    float ntu;
    float tegangan;
  String myStatus = "";
  
  //Setup Sensor TDS + Suhu
  #include <EEPROM.h>

  #define ONE_WIRE_BUS 6
  #define TdsSensorPin A1
  OneWire oneWire(ONE_WIRE_BUS);
  GravityTDS gravityTds;
  DallasTemperature sensors(&oneWire);
  //float temperature = 25,
  float suhu = 0;
  float tdsValue = 0;
  
  //Setup sensor jarak
  #define trigPin 11
  #define echoPin 12
  long duration, distance, tinggiAir;
  BlynkTimer timer;
  
  void sensorTDS()
  {
      //Sensor TDS + Suhu
      sensors.requestTemperatures();
      gravityTds.setTemperature(sensors.getTempCByIndex(0));  // set the temperature and execute temperature compensation
      gravityTds.update();  //sample and calculate
      tdsValue = gravityTds.getTdsValue();  // then get the value
      float suhu = sensors.getTempCByIndex(0);

     Blynk.virtualWrite(V6,tdsValue);
     Blynk.virtualWrite(V8,suhu);
  }

  void sendSensor(){
    tegangan = 00;
      for(int i=00; i<800; i++)
      {
          tegangan += ((float)analogRead(A0)/1023)*5;
      }
      tegangan = tegangan/800;
      tegangan = round_to_dp(tegangan,1);
      ntu = -49.17*tegangan+162.8;

     Blynk.virtualWrite(V5, ntu);
  }
  
  void sendTinggi(){
     digitalWrite(trigPin, LOW);
      delayMicroseconds(2);
      digitalWrite(trigPin, HIGH);
      delayMicroseconds(10);
      digitalWrite(trigPin, HIGH);
      duration =  pulseIn(echoPin,HIGH);
      distance = (duration/2)/29.1;
      tinggiAir = 17-distance;  
      Blynk.virtualWrite(V7, tinggiAir);
  }
  void setup()
  {
    // Set console baud rate
    Serial.begin(9600);
    delay(10);
    // Set ESP8266 baud rate
    EspSerial.begin(ESP8266_BAUD);
    delay(10);
    sensors.begin();
    gravityTds.setPin(TdsSensorPin);
    gravityTds.setAref(5.0);  //reference voltage on ADC, default 5.0V on Arduino UNO
    gravityTds.setAdcRange(1024);  //1024 for 10bit ADC;4096 for 12bit ADC
    gravityTds.begin();  //initialization
    pinMode(trigPin, OUTPUT);
    pinMode(echoPin,INPUT);
    pinMode(pengurasPin, OUTPUT);
    digitalWrite(pengurasPin, LOW); 
    pinMode(pengisiPin, OUTPUT);
    digitalWrite(pengisiPin, LOW); 
    pinMode(katapangPin, OUTPUT);
    digitalWrite(katapangPin, LOW);   
    Blynk.begin(auth, wifi, ssid, pass);
    timer.setTimeout(400, [](){
    timer.setInterval(1000L, sensorTDS);
    });
    timer.setTimeout(400, [](){
    timer.setInterval(1000L, sendSensor);
    });
    timer.setTimeout(500, [](){
    timer.setInterval(5000L, sendTinggi);
    });
  }
  
  void loop()
  {
  
    Blynk.run();
    timer.run();
  }
  
  float round_to_dp( float nilaibaca, int desimal)
  {
    float multiplier = powf( 10.0f, desimal );
    nilaibaca = roundf( nilaibaca * multiplier ) / multiplier;
    return nilaibaca;
  }

And here is my layout on blynk :

Thank you guys !

Software serial on the Arduino becomes unreliable at speeds above 9600
You should re-configure your ESP-01 to communicate at 9600, via an AT command, then change tour baud rate in the sketch to match.
