Just an observation, but the code for getting the temperature looks way too complex. What model of sensor are you using?

You need to include the spark-dallas-temperature library in your code.

To get the temperature in Celsius you can just do:

ds.requestTemperatures();
float celsius = ds.getTempCByIndex(0);

Also, you should probably change:

OneWire ds = OneWire(D4);  // 1-wire signal on pin D4

to

DallasTemperature ds(new OneWire(D4));

getSoilTemp should look like this:

void getSoilTemp()
{
  ds.requestTemperatures();
  float celsius = ds.getTempCByIndex(0);
  float fahrenheit = ds.getTempFByIndex(0);
  Serial.print("  Temperature = ");
  Serial.print(celsius);
  Serial.print(" Celsius, ");
  Serial.print(fahrenheit);
  Serial.println(" Fahrenheit");
}

Also, you can substitute a timer by putting this in your loop():

if (millis()/1000 % 1 == 0) // Every second
{
  getSoilTemp();
}
