Looking at your plots it seems you have an archive_interval of 60s (1 minute). While in my opinion there is no benefit having an archive_interval that low, the downsides are a fast growing database, a bad performance and kind of ugly plots, espicially with wind, windGust and windDir. The only advantage I can think of, by setting a shorter archive_interval than 300s, is you get a "more live" view of the currant weather and you don't have to wait for the archive_interval plus the time, the report generation and upload needs, to view what currently happening. If you don't want to relinquish having live data despite having an archive_interval that is producing nicer plot with a smaller database and a good performance: there are different skins that solve this problem. But this comes with extra configuration for the skin and things like MQTT for the live data.
Anyway: I'd always go for the standard value for archive_interval, which is 300s. [email protected] schrieb am Sonntag, 3.
