Hello
I am trying to get a RP3 to talk to a older Dallas OneWire weather instrument.
The WeeWx installation works with the simulator and outputs weather reports but will not start when I use OWFS as the driver in the weewx.conf.
The 1wire is connected to the RP3 via a i2C board and this is working as I can see data via a browser at localhost:2121
Using the latest build for Raspban.
On restart Weewx reports

Hi Gordon,
python3-ow disappeared from the RPI linux repo, which leaves you with
the fallback module - pyownet. That module is used along with the
requirement of a running owserver (from owfs, which it sounds like you
have one running already).
Mathews driver for the owfs has been forked to...
https://github.com/glennmckechnie/weewx-owfs
where there are additional notes in the README (as well as notes in
the drivers source).
That driver is working here, and has been used by others with weewx4
and python3 (also with an i-2C board) so once you're over that
initial module hiccup you should hopefully be okay.
basically, the notes for your issue are...
python3.x for weewx versions > 4
sudo apt-get install owserver
pip3 install pyownet (if it is not available via apt-get.
(use apt-get install pip3-python to install pip3 )
Once you have pyownet installed and running, that fork of the driver
should then work for you.

Hi Gary
python-ow installed just fine but python3-ow gives file not found unable to locate package error.
wee_extension --install weewx-owfs.zip worked.
sudo PYTHONPATH=/usr/share/weewx python /usr/share/weewx/user/owfs.py iface=i2c-1 --sensors
Gives
Traceback (most recent call last):
File "/usr/share/weewx/user/owfs.py", line 191, in <module>
from weewx.engine import StdService
File "/usr/share/weewx/weewx/engine.py", line 20, in <module>
import configobj
ImportError: No module named configobj
Even though I have installed configobj previously.
Any thoughts?
Cheers
Gordon

You need to follow Glenn’s advice.
As an aside you are running WeeWX under python3 so you need a python3 version of the python ow bindings; python-ow is a python2 library so that is why it does not work with your WeeWX install even though it was successfully installed
