My last edit reminded me. I started using the dallas temperatures library on the arduino so it's code is very different and much cleaner. It's still in bodge it together to see if it works stage though so it's far from pretty but here is the complete arduino code as it currently stands.

#include <OneWire.h>
#include <DallasTemperature.h>

// Data wire is plugged into port 22 on the Arduino
#define ONE_WIRE_BUS 22
#define TEMPERATURE_PRECISION 9
#define delayTime 2000     // the delay before restarting the loop

// Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
OneWire oneWire(ONE_WIRE_BUS);

// Pass our oneWire reference to Dallas Temperature. 
DallasTemperature sensors(&oneWire);

// arrays to hold device addresses
DeviceAddress s1, s2;

void setup(void)
{
  // start serial port
  Serial.begin(9600);
  
  // Start up the library
  sensors.begin();

  //printStatus();

  // assign address manually.  the addresses below will beed to be changed
  // to valid device addresses on your bus.  device address can be retrieved
  // by using either oneWire.search(deviceAddress) or individually via
  // sensors.getAddress(deviceAddress, index)
  //insideThermometer = { 0x28, 0x1D, 0x39, 0x31, 0x2, 0x0, 0x0, 0xF0 };
  //outsideThermometer   = { 0x28, 0x3F, 0x1C, 0x31, 0x2, 0x0, 0x0, 0x2 };

  // search for devices on the bus and assign based on an index.  ideally,
  // you would do this to initially discover addresses on the bus and then 
  // use those addresses and manually assign them (see above) once you know 
  // the devices on your bus (and assuming they don't change).
  // 
  // method 1: by index
  if (!sensors.getAddress(s1, 0)) Serial.println("Unable to find address for Device 0"); 
  if (!sensors.getAddress(s2, 1)) Serial.println("Unable to find address for Device 1"); 

  // method 2: search()
  // search() looks for the next device. Returns 1 if a new address has been
  // returned. A zero might mean that the bus is shorted, there are no devices, 
  // or you have already retrieved all of them.  It might be a good idea to 
  // check the CRC to make sure you didn't get garbage.  The order is 
  // deterministic. You will always get the same devices in the same order
  //
  // Must be called before search()
  //oneWire.reset_search();
  // assigns the first address found to insideThermometer
  //if (!oneWire.search(insideThermometer)) Serial.println("Unable to find address for insideThermometer");
  // assigns the seconds address found to outsideThermometer
  //if (!oneWire.search(outsideThermometer)) Serial.println("Unable to find address for outsideThermometer");

  
  // set the resolution to 12 bit
  sensors.setResolution(s1, 12);
  sensors.setResolution(s2, 12);

  
}

// function to print a device address
void printAddress(DeviceAddress deviceAddress)
{
  for (uint8_t i = 0; i < 8; i++)
  {
    // zero pad the address if necessary
    if (deviceAddress[i] < 16) Serial.print("0");
    Serial.print(deviceAddress[i], HEX);
  }
}

void printStatus(void)
{
  // locate devices on the bus
  Serial.print("Locating devices...");
  Serial.print("Found ");
  Serial.print(sensors.getDeviceCount(), DEC);
  Serial.println(" devices.");

  // report parasite power requirements
  Serial.print("Parasite power is: "); 
  if (sensors.isParasitePowerMode()) Serial.println("ON");
  else Serial.println("OFF");
  
  // show the addresses we found on the bus
  Serial.print("Device 0 Address: ");
  printAddress(s1);
  Serial.println();

  Serial.print("Device 1 Address: ");
  printAddress(s2);
  Serial.println();
  
  // print the device resolutions
  Serial.print("Device 0 Resolution: ");
  Serial.print(sensors.getResolution(s1), DEC); 
  Serial.println();

  Serial.print("Device 1 Resolution: ");
  Serial.print(sensors.getResolution(s2), DEC); 
  Serial.println();
}
// function to print the temperature for a device
void printTemperature(DeviceAddress deviceAddress)
{
  float tempC = sensors.getTempC(deviceAddress);
  //Serial.print("Temp C: ");
  Serial.print(tempC);
}

// function to print a device's resolution
void printResolution(DeviceAddress deviceAddress)
{
  Serial.print("Resolution: ");
  Serial.print(sensors.getResolution(deviceAddress));
  Serial.println();    
}

// main function to print information about a device
void printData(DeviceAddress deviceAddress)
{
  //Serial.print("Device Address: ");
  printAddress(deviceAddress);
  Serial.print(",");
  printTemperature(deviceAddress);
  Serial.println();
  delay(30);
}

void loop(void)
{ 
  // call sensors.requestTemperatures() to issue a global temperature 
  // request to all devices on the bus
  //Serial.print("Requesting temperatures...");
  sensors.requestTemperatures();
  //Serial.println("DONE");

  // print the device information
  printData(s1);
  printData(s2);
  delay(delayTime);
