or not ;-(

After re-powering the board, the sensors reverted to the 85C state:

  "search": [
    "28cc2e230500006b",
    "283260dc04000001"
   ]
 }
initial: 85
initial: 85
=undefined
0: undefined
1: undefined
{ "cb_temp": 26.3125 }

I guess if you executed other code before the first actual call to getTemp() this would work out ok....

By setting the mode to 9 bit so the conversion is shorter:

var sensors = s.map(function (device) {
  var t=ds.connect(ow, device);
  t.setRes(9);
  t.getTemp();
  t.setRes(12);
  return t;
});

{
  "search": [
    "28cc2e230500006b",
    "283260dc04000001"
   ]
 }
initial: 25.4375
initial: 24.0625
=undefined
0: undefined
1: undefined
{ "cb_temp": 25.875 }
{ "cb_temp": 24.9375 }
