When you say it is missing the names in the string, do you mean the row names?

In other words, you are creating a CSV file, do you want the first row to be the column names OR do you want the data string to contain both the value of the sensor and sensor name?

currently looks like this: 1527420724072,18.125,19.625,18.125
do you want it to be:1527420724072,“Head_Temperature”, 18.125,“Condenser_Temperature”,19.625, “Parrott_Temperature”,18.125
