That's a lot of questions! Answer to a few of them: Wettest day of the month: $month.rain.maxsum Time of the wettest day of the month: $month.rain.maxsumtime Driest day of the month: $month.rain.minsum Time of the driest day of the month: $month.rain.minsumtime
Similar pattern for the wettest / driest day of the year. Similar pattern for the wettest / driest day for all time (use tag $alltime) To get wettest/driest month or year would require some custom code (aggregates like ".maxsum" work only for days). You can either write a custom search list extension <http://www.weewx.com/docs/sle.html>, or a custom xtypes aggregation <https://github.com/weewx/weewx/wiki/WeeWX-V4-user-defined-types>. See the xtypes extension weewx-xtypes <https://github.com/tkeffer/weewx-xaggs>. You may find it useful if for no other reason than as a guide to how to write a custom aggregation. It wouldn't be hard to extend it to do things like historical highs and lows for months and years. -tk On Sun, Sep 25, 2022 at 6:00 AM michael.k...@gmx.at < michael.kainzba...@gmx.at> wrote: > How to calculatate the maximum or minimum daily/monthly/yearly sum of a > value? > > E.g.: the wettest day of the month (so far)?
