this is the place to ask. maybe there is someone else running a ws23xx on 
an rpi?

i am running a ws23xx but it is on an x86_64 system (with an ancient 
version on debian), i'm afraid i am not much help

Linux saga 3.2.0-4-amd64 #1 SMP Debian 3.2.81-2 x86_64 GNU/Linux

can you try running weewx on an x86/x86_64 system?

you might have to hunt around the rpi forums for information about serial 
and usb-serial settings.  i seem to recall the rpi default configuration of 
the modem/tty causing problems for some serial communications.

you could also look at some of the resources listed in the comments in the 
ws23xx.py driver file.  the driver is based mostly on Russell Stuart's 
implementation, with some bug fixes.  if you can get his original 
implementation to work, that might provide a clue about what is different 
about the serial setup on arm/rpi.  or perhaps try the Kenneth Lavrsen 
Open2300 implementation.

i'm happy to incorporate whatever you find so that the weewx ws23xx driver 
will work reliably on any platform, but i'm afraid i do not have time right 
now to set up an rpi or other arm platform to do the exploratory work.
