Getting wrong values when reading data from sensors with i2C TCA9548A i2C multiplexer getting bad values from BMP180 sensors multuplexer TCA9548A

DRY ^^
I think I get it you something like that?


#include <Wire.h>
#include <SFE_BMP180.h>

  SFE_BMP180 pressure;
//  SFE_BMP180 pressure_1;
//  SFE_BMP180 pressure_2;
//  SFE_BMP180 pressure_3;



#define TCAADDR 0x70
  void tcaselect(uint8_t i) {
  if (i > 7) return;
 
  Wire.beginTransmission(TCAADDR);
  Wire.write(1 << i);
  Wire.endTransmission();  
}

int maxtca=4; // nombre de voies utilisées

void setup() {
  Serial.begin(9600);
  Wire.begin();
          
  Serial.println("Starting Initialization");     
 
pressure.begin();
//   delay(100);
//pressure_1.begin();
//   delay(100);
//pressure_2.begin();
//   delay(100);
//pressure_3.begin();

Serial.println("Initialization Finished");


}

void loop() 
{ 
  char status;
for (byte tca = 0; tca < maxtca; tca++) { tcaselect(tca); 
  double T,P;

  status = pressure.startTemperature();
  if (status != 0)
  {
    // Wait for the measurement to complete:
    delay(status);

    status = pressure.getTemperature(T);
    if (status != 0)
    {
      // Print out the measurement:
      Serial.print("BMP: ");
      Serial.print(tca,1);
      Serial.print(" _ T: ");
      Serial.print(T,2);
    Serial.print(" °C, ");

      status = pressure.startPressure(3);
      if (status != 0)
      {
        // Wait for the measurement to complete:
        delay(status);

        status = pressure.getPressure(P,T);
        if (status != 0)
        {
          Serial.print("P: ");
          Serial.print(P,2);
          Serial.println(" mb ");
        }
        else Serial.println("error retrieving pressure measurement\n");
      }
      else Serial.println("error starting pressure measurement\n");
    }
    else Serial.println("error retrieving temperature measurement\n");
  }
  else Serial.println("error starting temperature measurement\n");   
 };  
    

   delay(1000);   
 
}

This "works" but it doesn't change the results

TCA9548A and BMP1802
