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.
