> Unfortunately no simple or neat solution given WeeWX is not daylight saving aware
Well, looking on how the template is coded, the simple solution is such a no-brainer, I didn't even think of it. And that although you proposed it, you wrote the above, that there ist no simple solution: "So I suspect the issue is just with the label. You are manually setting the day_delta to 30, why not simply hard code the label" which is the simple solution, so thank you for that. https://github.com/brewster76/fuzzy-archer/blob/master/skins/Bootstrap/rain.html.inc#L20 But anyway, I also wonder what is really the issue. It may or may not be just the label. depending on how the day_delta sum is calculated. Is it the sum of the archive_day sums? Is it the sum of archive's rain column, over 30 x 24h? When I manually calculate the sum of the last 6 days of the previous month, and add it to the current months sum, I am (currently) off by 0.1mm, which is exactly the amount that was measured after the current daytime on day 31 in the past, from now. So the the data source is "archive" table, but I don't know if the DST changed could influence the total in a corner case. This total is wrong if you interpret the value as "sum of the latest 30 calendar days", but may be correct, if interpreted as "sum of the latest 30 x 24h". But I don't know if it is really calculated that way. gjr80 schrieb am Donnerstag, 24.
