You are not telling us enough information. The archive field 'rain' should be the amount of rainfall in the archive period. What is your archive period? How often do you read the text file? What data is in the text file? Weewx does not use a rain value for 60 minutes. If the data from the text file is the daily accumulation then the driver needs to calculate the difference between two successive readings to determine the rainfall for the archive period.
The 'weewx page' can display whatever you want!! It is updated every archive interval. Rainrate will be the rain rate for the last archive period recorded, and the total will be an accumunlation of the rain column for all the daily archive records (and will probably actually be taken from the daily summary table). You need to be much more precise in your questions, and ideally you should tell us what data you have actually got in the database compared to what you expect to have.
