While looking for solution to my issue, I came around this post. I am using fileparser to log data from my remote weather station (Ecowitt) and everything works fine except the rain. I have implemented my own pre-processing where I log the delta-rain but that doesn't work for some reason (might my timing issue in the scripts). I am logging the dailyRain and other values, too. Just in case. I don't know how to e.g. use the dailyRain in the NOAA report.
As I read this: https://github.com/weewx/weewx/issues/491 I assume this could resolve it. Are there any more details on the use? sreda, 6. maj 2020 ob 00:00:03 UTC+2 je oseba John Kline napisala: > If you have some experience programming, you might consider writing a > driver for your weather station (as opposed to hacking something just for > rain). > > See: > http://www.weewx.com/docs/customizing.htm#porting > > On May 5, 2020, at 1:56 PM, Johann Schneider <johann.s...@gmail.com> > wrote: > > > Hello everybody! > Thank you for your answers. > Sorry for my difficult to understand question. > So my weather station sends the measured values every 15 seconds. > If it sends rain, I get the hourly rain value and the rain value for the > whole day.
