If you are importing a single record and using rain = cumulative the imported rain and rainRate values will always be zero, this is expected behaviour. The reason being that WeeWX records rainfall data on a per archive interval basis; in other words each archive record contains the rainfall that was recorded in that archive period, for example in the last five minutes if using a five minute archive interval. When the import source rainfall data is cumulative or a running total wee_import calculates the rain field value as the difference in this cumulative or running total value between successive records. The If there is only one record then this difference cannot be calculated and hence rain is recorded as zero. Likewise for rainRate; if there is no rain data then there can be no rainRate.
The use of the rain config option in a CSV import config file is covered here <http://weewx.com/docs.html/latest/utilities.htm#csv_rain> in the Utilities Guide <http://weewx.com/docs.html/latest/utilities.htm>. If you must import a single record at a time you must convert your source rain data to be a per-record value and import using rain = discrete. wee_import was not designed with the regular import of single records in mind, rather it was designed for the bulk import of days/months/years of data.
