Hi, 
Due slow death of my old weather station ( Lacrosse WS2-550, monitored and 
saved for 14 years with Weather Display ) and death of dedicated laptop 
(very similar age) running Weather Display,  I'm trying to move to new 
weather station (DYI Based ) and to weewx. 

I made weewx 5.1 working over weekend (connected by MQTTSubscriber/Driver 
to my weather station), but I have failed with importing of historical 
data. WD Import in documentation 
(https://weewx.com/docs/5.1/utilities/weectl-import-wd/#mapping-data-to-archive-fields)
 
maps log file field *rainlastmin* to weewx field *rain*. Unfortunatelly, 
this field is 0.0 in my log files and only accumulated *dailyrain* log 
field is properly populated.  I tried to map field *dailyrain *with units 
*mm*  and reimport (no errors during import), but it seems that weewx field 
rain expects really delta in particular minute. I have checked it on 
1.1.2024, where 0.3mm rain happened on 19:57.  I checked base records, and 
between record 1187 and 1425 (last minute of day) is in database stored 
value 0.03, so import works, but NOAA report ( and archive_day_rain table)  
shows total rain value for day 7.17. After some investigation, I found that 
7.17 is close to (1425-1187)*0.03
I have changed all units to METRIC ( for me easier to calculate than US 
units) , generated new database before running import. 
My main questions/issues :
Any idea, how to fix import ? 

Is really weewx rain field expected to be *rain delta* from last period (I 
need to adjust code of my Weather station to provide this form of data)  ?

Thanks, Vaclav
