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. The rain value for the whole day is cumulative and is set to 0 at 00:00. The hourly rain value at the beginning of the rain is always calculated for one hour. I thought I could simply import the data into weewx with "fileparser". This also works with the other data. Just not with the rain values. John Kline's suggestion sounds great. That's how I would have imagined it. How can I implement something for the rain value?
