Problems with temperature sensor

[tomasandersson]

Hello
I have 10 dallas temp sensor into to an Arduino. The problem is that sometimes domoticz mixes temp sensors together. Any more having the same problem? Or does anyone have a solution.

Hi I also use DS18B20 but I have not any problems with the controller mixes the DS18B20. But all DS18B20 has a unique address, which you can read out and use.

No experience with domoticz, but this may help nevertheless: https://github.com/rejoe2/MySensors-Dallas-Address-ChildID-Consistency
You will find some sketches for using more than one DS18B20 on one bus and some explanation also.

General remark: as long as you do not change your hardware setup, you should find the same point of measurement reported under a specific temp-Child-ID using the standard sketches. The sketches above go a little further wrt. this.
