In the meantime all my problems seem to be resolved - probabely due to
recent software updates:
1. No longer any USB problem after upgrading to recent raspbian (buster
5.4.72-v7+).
Previously, I encountered USB problems after some weeks. To detect them I
wrote a simple watchdog and rebooted my raspberry automatically. After
reboot USB always did recover. Additionally I did a reboot once per day.
Now these problems are gone, and my raspberry is up since 38 days (the day
when I did the upgrade onto buster).
2. I've updated to weewx 4.x based with python 3.
Beware, to use python 3 you have to use ANOTHER repository (see the
corresponding weewx documentation). If you don't switch the repository you
will stay with python 2. AND you must use special releases of the wh23xx
driver (NOT the official one, it's still at pyhton 2 as far as I know) and
for forecast.
Concluding: After all these changes all my problems with that kind of
weather station are gone. Maybe one exception: If there is very heavy rain,
the base station will loose its contact with the sensor array despite the
short distance (only some meters). But of course that's not a weewx problem.
I even use the same raspberry to run FHEM smart home and kodi multimedia.
