Hi all,
I have created a system but when viewing the serial out put I get "No more addresses" at the end of the serial output. I have had a look through my code but I cannot find the statement being put at the end only at front of the program where if the sensor is not found then this statement is displayed.
I will attach my program, just to clarify The highlighted text is what I do not want in the serial output (see capture.png).
Sorry if I've worded it awkwardly!
Here is my code as requested 
#include <U8glib.h>
#include <OneWire.h> //temperature lib
OneWire ds(10); // declare on pin 10 with a 4.7 ohm resistor
U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NONE|U8G_I2C_OPT_DEV_0); // I2C / TWI
void setup()
{
//start serial connection
Serial.begin(9600);
//configure pin2 as an input and enable the internal pull-up resistor
pinMode(A5, INPUT); //Water Sensor
pinMode(13, OUTPUT);
pinMode(9, OUTPUT); //Buzzer
beep(50);
delay(1000);
if ( u8g.getMode() == U8G_MODE_R3G3B2 ) {
u8g.setColorIndex(255); // white
}
else if ( u8g.getMode() == U8G_MODE_GRAY2BIT ) {
u8g.setColorIndex(3); // max intensity
}
else if ( u8g.getMode() == U8G_MODE_BW ) {
u8g.setColorIndex(1); // pixel on
}
else if ( u8g.getMode() == U8G_MODE_HICOLOR ) {
u8g.setHiColorByRGB(255,255,255);
}
}
void loop()
{
byte i;
byte present = 0;
byte type_s;
byte data[12];

float celsius, fahrenheit;
//read the sensor value into a variable
int waterVal = analogRead(A5); //read the waterlevel and put it to an int
Serial.print("The water value is "); //print out the value of the sensor
Serial.print(waterVal);
delay(1000);
if (waterVal > 570) { //if the water value is above 700 the led comes on and buzzer beeps
highwater();
}
else

digitalWrite(13, LOW);
}
if ( !ds.search(addr))

Serial.println(F("No more addresses."));

// we might do a ds.depower() here, but the reset will take care of it.

}

void beep(unsigned char delayms)

Here is the output:
