Hello,

Since 21.10.2019 my UV plot is not generating.

I am getting error atached in weewx.err file. I also attached skin.conf and weewx.debug file. And I selected UV column from database from 20.10.2019 in archive.txt file. If you can help me to point me right direction how to fix this issue I will be very glad.

I have problem to generate plots for historical months  12.2014, 1.2015, 2.2015 (rain, wind direction, UV),  This problem in historical data occures since I updated to 3.9.0 if I am not mistaken. Historical plots I generate using wee_reports utility with timestamp parameter and specific skins for generating month and year plots. I can attache error log too but my priority is to fix generating of actual plot.

Thank you.
archive.txt
skin.conf
weewx.debug
weewx.err

I notice that the error occurred at a time when there was no database record: 28 October, 09:10. That should result in an error "generate time not in database" and the templates skipped.

Let's see if that has anything to do with the error. Could you try running wee_reports for that record, and then again for a record near then?

Hello, thanks for reply. I tried with time after 9:10, at 9:10 and before 9:10 all with same results. The gap in data is only because around 9:10 I restarted computer with weewx. But gap in data never created this kind of error beforeso I don't know if it can be this case.

OK, I think we're going to have to instrument the function. Please temporarily replace your copy of /usr/share/weewx/weeplot/utilities.py with the attached.

Then try running wee_reports again, then post the log.
