Which pywws data file? (raw, hourly, ...) What period is the station console showing? (hour, 24 hour, ...)

The water comes from a bottle I used for test.

Rain rates of more than 5 mm per minute are assumed to be corrupt data and are ignored. (There can be problems if the wind gets into your rain gauge and rattles the see-saw from side to side.) You should get a warning message, depending on the verbosity you run pywws at.

If you have exceptionally high rainfall rates where you live then you can edit pywws/process.py and change line 266 accordingly.

Okay, there are many places where it rains a lot in a short time, so you might want to comment this in a text file :)

These cheap weather stations won't accurately record such high rainfall. Most of it will bounce off the funnel.
