Sorry, in case I create too much spam, but I'm trying to dig deeper into WeeWx and while I was checking out the database structure I can not fully understand how the day tables are managed. I'm using mysql so I checked the weewx/manager.py (the DaySummaryManager classs) and all mysql.py files.
The daily tables look like this (e.g for my temperature): [image: pic.png] <about:invalid#zClosurez> I first assumed that every observation type (like radiation, temperature, rain etc.) gets it's own daily table (and that is right). Then every daily table contained one row for every day the station was up and running and every row will have a min and max value of that day (for the specific observation type). I could not test the station over a longer period of time so far but to me it seems that a daily table will always only hold one single row? I'm confused as as you can see in my picture posted above, the dateTime is from the day before (02.03.2019) and the min/max timestamps are from another day, the day after (03.03.2019). How will weewx get the hi/lo values for every single day in a month for example if the daily tables only hold one single row? It's been a long day so maybe I'm just being dumb right now but I'm confused and I don't like being confused ;). I hope someone will be so kind to clear this up for me. Thank you very much, henry.
