***Note that it is perfectly possible to have two successive lines in a standard log file with same time, although this should not happen in normal running, it can result from a hiccup or other interference on your device. If you are asking MX to upload the contents of this file, a second line with same time is ignored, only the first line with a particular date and time is uploaded. | |||
** All Remaining fields are spot values, either what has just been read from your station, or a derived value calculated from a set of values read from your station. For these value fields, Cumulus may have converted from the unit used by your weather station to the unit that you have requested to use, and there will be some inaccuracy inevitable in such conversions. Where the value to be stored is a real number with decimal places, Cumulus will use a decimal comma or decimal point depending on which is defined in your locale, do be careful not to change that locale if you need to change your device or update it, as Cumulus can only read files where the same decimal separator is used everywhere. | ** All Remaining fields are spot values, either what has just been read from your station, or a derived value calculated from a set of values read from your station.
