Topic: WeeWX - Weather34 template daily Chart not available

[lombaseggel]

Hi all,

i had a well working WeeWX installation with the weather34 template. Since today 1.45 there is no more update of the daily chart. I see only monthly and yearly csvīs beeing generated in the chartdata. Any ideas how to fix that? My site: steinenbronn-wetter.de

I don't use weather34 template, but my guess is that something in your setup changed to Daylight Saving Time at 2am, when DST took effect here in the states (if I'm correct, it shouldn't have in Germany, do you have a console set up for the US or something?).

So first I would make sure all your components are on the correct time, and then back up your data before trying the next step.

I also had trouble with my setup after the DST change.  I solved it on my Davis VP by using the command

Code: [Select]

wee_device --dump, hopefully the missing reports will be generated at the next archive interval, or you can rebuild them.  Dumping the data logger does not clear the logger, but "dumps" it to the database, so if it doesn't work for some reason your data is still there (but still back up before hand just in case).

Thanks SnowHiker!
The option --dump is not available with my hardware. All time settings are fine
I see this errors in the log:

i read that this can be caused by a sensor beeing offline. As the other reports are fine, i will wait till tomorrow morning to see if this solves on its own

Thanks
