@damien
Is there an update for this sketch to use in V2?

@gohan
Due to work related schedule problems I won't be able to work on this code for a few weeks......

@gohan hey Gohan,
I will not be able to continue to work on my code till after the weekend....

@gohan oh.... ok..... pretty new at coding, but I guess you allready figured that out.....;-)

@gohan so I fixed that....... and now I get this in Domoticz....

so it seems I do get temp Id's from 17 to 32, but the values stay in 0,1,2 where the relays 1 and 2 don't work.....

@gohan seems like it's only early for one of us...... I,ll change it later today.....

@gohan seems like it's early for both of us.....;-)

@gohan no I didn't...

  // Present all sensors to controller
  for (int i=17; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
     present(i, S_TEMP);

    // Then set relay pins in output mode
    pinMode(pin, OUTPUT);
