1. Just delete the plots. They will all get regenerated. 2. You had the classic "no clock" symptoms: when the reboot happened, the system started with the last time it had saved, which was hours old. This always causes unpredictable results. See the wiki article *Raspberry Pi <https://github.com/weewx/weewx/wiki/Raspberry-Pi>*.
It's well worth spending the $5 and installing a realtime clock. -tk On Sun, Jun 21, 2020 at 12:42 PM michael form <mike.f...@gmail.com> wrote: > I have attached a section of the syslog file.
