Klimalogg driver fails after update to weewx 5.0.0.1

[Marco Biner]

Hello

seems that I am one of the rare users of the kl.py application from Matthew Wall.

As google does not help me with a solution here my problem.

After the last update of weewx to version 5.0.0.1 kl.py fails importing the driver:

the log file reports:

any help would be fine.

So this is a package install? Did you do try restating already? A friend had the same error with a package install update 5.0.0 =>  5.0.1 on Raspberry Pi OS, but with the ws23xx driver. He restarted the OS, then it worked. Maybe restarting udev or another daemon is sufficient also, I don't know.

Hi Michael

thanks for your hint, after a reboot it works, I did not assume that debian adapts wind*ws style to do a reboot after updates.

With new Version 5 installs, the user owning the daemon has changed. That sometimes requires logging out, then logging back in. A reboot should not be necessary.

reboot is not necessary.  however, it might be the easiest thing to do.  on most recent operating systems, the udev rules will take effect immediately.  if they do not, then unplug-then-replug the device will make them take effect, even on older operating systems.  the other part is ensuring that the owner of the daemon user is in the right group.  restarting the daemon process is sufficient to make that happen.

this should explain the ws23xx case, since the udev rule for that device is included in a weewx install.

in the case of klimalogg, the udev rule is also included with weewx, even though the kl.py driver is not.

if you install weewx using deb/rpm, it should just work.  check the udev file at /usr/lib/udev/rules.d/60-weewx.rules.

if you install weewx using pip, then you must install the udev rules that came with weewx (the setup-daemon.sh script will do this for you).  check for the udev rules at /etc/udev/rules.d/60-weewx.rules

NB: klimalogg uses the same usb transceiver used by the lacrosse ws28xx stations.  that transceiver uses product/vendor identifiers of 5555/6666.  those identifiers are the equivalent of using 'example.com' - ok for testing, but not what you should ship in your product.  but they did.

Hi Matthew

thank you for the detailed explanation.

As I am using the kl.py to survey the climate in my house together with a heatpump contolled by a solution from https://www.ta.co.at/ each update of weewx brings some surprizes :-)

But I am still convinced that Keffers application is a very good tool.
