weewx status throws a bunch of error which I can't figure out. Could you please help me to fix them? (earlier, weewx was working fine, but I don't know if the current issue is related to new linux OS or weewx.) Any help is much appreciated, thank you.

Probably an issue with the [WS23xx] section in your weewx.conf file. In particular, check the "port" option and make sure it is correct.

If you wish, you can post the section here and we can take a look at it. Just post the [WS23xx] section --- nothing else. We don't need to see passwords.

Many thanks, here is the config. Note: during my earlier installation of weewx (a few years ago), it doesn't ask for the port, but now in 2022, the installation asked for port and I did set one based on

$ ls /dev/usb/
hiddev0

$ cat /etc/weewx/weewx.conf
[WS23xx]
    # This section is for the La Crosse WS-2300 series of weather stations.
   
    # Serial port such as /dev/ttyS0, /dev/ttyUSB0, or /dev/cuaU0
    port = /dev/usb/hiddev0
   
    # The station model, e.g., 'LaCrosse WS2317' or 'TFA Primus'
    model = LaCrosse WS23xx
   
    # The driver to use:
    driver = weewx.drivers.ws23xx

The complete config is here https://pastebin.com/yTy3ShdT

The port should be a serial port, not a USB port. Something /dev/ttyUSB0. 

Unplug your station, then plug it back in, then use the command 'dmesg'. It may (or may not) tell you what the serial port is that it connected to.

my bad, I supposed to use wh23xx driver, not ws23xx driver

I'm using USB port but not serial port
/dev/usb/hiddev0

It works well now! thanks
