Hello everybody!
I have a little problem. Sorry for my very bad english. I come from Germany
and my English is not the best. My experience with weewx is also very
limited. I built a weather station 3 years ago. It consists of an Arduino
Mega and several sensors.
Among other things, a rain sensor that reports 0.16mm of rain per seesaw
The values are pushed to iobroker (similar to openhab) every 15 seconds.
Here is an excerpt from my Arduino codes:

The rain data are given every 15 seconds.
I get the values for rain of the last hour and the total amount since
midnight.
Now I have tried to collect the data using fileparse.
Iobroker writes the data to a file every minute.
See example:
outTemp=43.8
outHumidity=74.7
pressure=29.896
rain=0.00
windSpeed=0.8
Fileparse evaluates the data and pushes it onto weewx.
Unfortunately, the data is summed up every few minutes and the values no
longer fit.
For example, I have 0.15mm of rain in the last hour, then the value after
each loop adds up until the hour is over.

Is there a solution?
