Your problem sounds very like the one encountered by Howard Walter and described at "weewx-owfs failure with new Raspbian Stretch" https://groups.google.com/d/msg/weewx-user/CfhGLIF8aaU/W5fEscuPBQAJ That link points to the last post in the thread with a confirmed solution. Step through the method there and see if it then works again. In short, everything was setup as it should have been (as it was when working before) except for those same error messages. Dec 7 17:35:26 wx OWFS[23185]: DEFAULT: owlib.c:(208) Cannot open USB bus master Dec 7 17:35:26 wx OWFS[23185]: DEFAULT: owlib.c:(52) No valid 1-wire buses found Dec 7 17:35:26 wx OWFS[23185]: import of driver failed: (<class 'ow.exNoController'>) The solution is to install and run owserver, then point owfs.py to use that through ' interface = localhost:4304 ' rather than ' interface = u '. It still uses the usb dongle, just via a different route. Before you implement that change. What version of python-ow and owserver (if installed) are you running at the moment? apt show ow-python apt show python-ow also run them after the change has been implemented to catch owserver if it was missing (and any update to python-ow.) And, can you also post the section from weewx.conf that lists your OWFS configuration ...
