In this line:<\/p>\n

int insideThermometer = (int)insideThermometer;\n<\/code><\/pre>\n
You create a local variable and assign it to itself. Not what you wanted. The global var you are trying to use is <\/p>\n
DeviceAddress insideThermometer = { 0x28,  0xFF,  0x83,  0x51,  0xB2,  0x17,  0x4,  0x8A };\n<\/code><\/pre>\n
If you look at the source code<\/a>, DeviceAddress<\/code> is typdef’d as <\/p>\n
typedef uint8_t DeviceAddress[8];\n<\/code><\/pre>\n
If you want to get the temperature you need to call sensors.getTempC(insideThermometer)<\/code>, which you already do in the printTemperature<\/code> function. Since you call that function before testing the temp, just modify it to return the temp:<\/p>\n
float printTemperature(DeviceAddress deviceAddress)\n{\n  float tempC = sensors.getTempC(deviceAddress);\n  float tempF = 0;\n  if (tempC == -127.00) {\n    Serial.print(\"Error getting temperature\");\n  } else {\n    Serial.print(\"C: \");\n    Serial.print(tempC);\n    Serial.print(\" F: \");\n    tempF = DallasTemperature::toFahrenheit(tempC);\n    Serial.print(tempF);\n  }\n  return tempF;\n}\n<\/code><\/pre>\n
Then change to<\/p>\n
int insideTempF = printTemperature(insideThermometer);\n....\nif (insideTempF > mintemp) {\n    ....\n<\/code><\/pre>\n
(You may want to change the name of the function to something like printAndReturnTemperature<\/code> as that more clearly states its new functionality.)<\/p>\n<\/p><\/div>\n
