I have done this but all devices with different ROM Have the same temperature but only one Thermocouple is connected. That is the Problem! hmm
I do not understand why. I get different ROM addresses, but all send me the same Temperature.
If i test my script with one ROM that is not correct it writes wrong device. So the CODE should be ok!
I defined it like this
DeviceAddress Max1 = { 0x3B, 0x94, 0xE2, 0xDF, 0x02, 0x00, 0x00, 0xFE };
then
float tempC = sensors.getTempC(Max1);
but all ROMs that I test shows the same Temperature. What is wrong with me
