Fileparse Installation Issue

Hi All,

I have a fresh install of version 5.2.0 running on a Raspberry Pi running Trixie OS. The installation went smoothly with no issues except I did have to add myself to the weewx group in order to access files. The issues came when I attempted to use the fileparse driver. I installed the driver using the following command:

weectl extension install /etc/weewx/examples/fileparse

When I executed the command I got the following error:

pi@raspberrypi:~ $ weectl extension install /etc/weewx/examples/fileparse
Using configuration file /etc/weewx/weewx.conf

Can someone point me in the right direction?

Thanks in advance!

Probably a permissions problem. Try adding yourself to the 'weewx' group:

sudo usermod -aG weewx my-user-name
exec bash

-tk

Hi Tom,

I confirmed that I (user pi) am in the weewx group and ran the command as you suggested, but the outcome is the same! I tried running the command using sudo and it worked!

Any ideas?

Addtional information. After running the command the fileparse installation appeared to finish successfully, however, when I started weewx, it failed with the following:

Permission denied generally means you tried to read or write from/to someplace you aren't in the required group to succeed doing that. The problem going away via sudo (which you shouldn't almost ever need to do typically for weewx v5) generally confirms that.

Keyerror frequently means a typo or something missing from weewx.conf so you probably should post that for more eyeballs taking a look.

FWIW, on my system while files are assigned to the weewx group, group permissions are 400 (read-only).

This was a fresh install of weewx 5.1.0 using `apt install weewx` on Unbuntu 24.04

You have 'station= fileparse' all in lowercase but your stanza is [FileParse] in mixed case, which I think is your problem.

Try 'station = FileParse' and see if that helps.

The key error likely is you are defining a station type with no matching [name] stanza.

Hi Vince,

That was it! Changed to match the stanza title and all is well!

Thanks to all who contributed!
