Installed 4.4 using latest install method in documentation - configure apt,
install. It runs fine. Then I look for the "latest" info on installing
owfs, and I found and followed this
https://github.com/weewx/weewx/wiki/owfss & I read the introduction.
At this point I should note I have previous weewx running for several yrs
including a Davis and the Sheepwalk "rpi3v2" pi hat which provides ow bus,
the 4 measurements are incorporated into my system just fine. I installed
that using the setup.py, and I'm sure I followed something similar to my
above quote, if not that exactly. I'm not going to touch that setup.
This
sudo PYTHONPATH=/usr/share/weewx python /usr/share/weewx/user/owfs.py
--readings
has NEVER worked for me even on the existing PI3b running weewx 3.91 but
data comes through fine, so I wasn't surprised about it. Anyway here is
some pertinent settings:
pi@PI4BUSB:~ $ sudo python -V
Python 2.7.16
Note: I also have Python v3 installed, it was installed via pip3 to get the
almanac stuff.

Weather station type: Simulator

Somewhere I have gotten caught up in the disconnect between the different
documentation between github & Weewx documentation. Like I said, I have
this ow host adapter running just fine on weewx 3.9.1 on a Pi3b, for
several years, installed via setup.py method (although my instint tells me
the setup method may not be the problem).
I'd appreciate your help, Thanks.
