Update Raspberry Pi

[Stefan Heidrich]

Hello,

translated from German using Deepl

I updated my Raspberry Pi today, and Weewx was also updated from 5.2.0 to 5.3.1. Unfortunately, I wasn't paying attention and didn't notice that /etc/weewx/weewx.conf was set to a default configuration with the simulator. I was able to delete the incorrect entries in the database by deleting the entries from that time period:

SELECT COUNT(*)
FROM archive
WHERE FROM_UNIXTIME(dateTime)
BETWEEN '2026-05-24 10:00:00'
AND '2026-05-24 10:45:00';

But how do I remove incorrect data—such as evapotranspiration, UV index, and solar radiation—from the analysis? I also don’t really want to see the battery status for the indoor temperature sensor, transmitter, console battery, heater voltage, power supply, and reference, since they aren’t available.

Hi John,

thanks for your reply, but it doesn't really help me. I deleted the incorrect data in the ET, UV, and radiation tables, but the graphs are still coming up blank. Unfortunately, the wiki article doesn't explain how to prevent this.
And it doesn't explain how I can remove the irrelevant data for signal quality, internal temperature sensor, transmitter, console battery, heating voltage, power supply, and reference from the sensor status. I'd also like to get rid of the current UV index and solar radiation readings. Could you please tell me how to do that?
And why is the current, functioning station replaced by the simulation during the update in the first place?

 I'd also like to get rid of the current UV index and solar radiation readings. Could you please tell me how to do that?

That's covered by the wiki page, specifically

echo "UPDATE archive SET UV=NULL;" | sqlite3 /var/tmp/backup.sdb

Then you need to drop dailies and rebuild them, this is covered on the wiki page too

weectl database drop-daily

weectl database rebuild-daily 

And why is the current, functioning station replaced by the simulation during the update in the first place?

 

 I've never had that happen when I upgrade so I can't tell you
