Back around May 2020 the python3-ow version of ow disappeared from the RPi and Debian repos. Where it went, or why no-one knows. There is a user group post titled "python3-ow for OWFS" where this cropped up.
All that aside, you need pyownet (the module using 'pip3 install pyownet' if the apt repo doesn't have it) and owserver (from OWFS using sudo apt-get install owserver). The following is a fork of the original owfs driver / service and is known to work with weewx4 and your i2c combo. You should also find that the --readings stanza should work with this version. https://github.com/glennmckechnie/weewx-owfs The README at that fork should hold enough info to expand on those dependencies, if not ask for clarification. pydoc_owfs.txt will also hold some clues regarding the owserver configuration. ie:- server: device /dev/i2c-1 # for a pi using i2c-1 server: port = 4304 On 02/04/2021, vince <vinceska...@gmail.com> wrote: > There appear to be two pages in the wiki with slightly different filenames. > > Try https://github.com/weewx/weewx/wiki/owfs and look at step1 which > mentions python3 specifically. > > On Thursday, April 1, 2021 at 11:38:52 AM UTC-7 vince wrote: > >> If you use python3, you need python3 versions of all python modules 'and' >> >> python3-compatible versions of all drivers, extensions, and skins you >> install. >> >> That should be somewhat obvious I'd hope, given hundreds of posts since v4 >> >> came out with people battling the python3 transition. >> >> On Thursday, April 1, 2021 at 9:14:13 AM UTC-7 messyp...@gmail.com wrote: >> >>> I didn't see anything in the documentation I read about how to get "the >>> python3 version of the library the driver needs".
