Thanks Gordon.

Here is the code modified to save the results to an array, updating every 1/2 sec and displaying every sec:

var pin = D5; // update for your hardware!
var ow = new OneWire(pin);
ds = require("https://raw.githubusercontent.com/espruino/EspruinoDocs/master/devices/DS18B20.js");

var s = ow.search();
console.log({
  search : s
});
var sensors = s.map(function (device) {
    return ds.connect(ow, device);
  });

var temps = [];
setInterval(function () {
  sensors.forEach(function (sensor, index) {
    sensor.getTemp(function (temp) {
      temps[index] = temp;
    });

  });
}, 500);

setInterval(function () {
  console.log(temps);
}, 1000);

{
  "search": [
    "28cc2e230500006b",
    "283260dc04000001"
   ]
 }
=undefined
