The biggest hurdle was the requirement to run owserver and the problems some were encountering when starting it under systemd. That has possibly been solved with Nevilles find and that is documented in the readme at... https://github.com/glennmckechnie/weewx-owfs But, I believe you now have a working owserver so that issue is mute. > Others seemed to have better luck installing Weewx using Python 2.

Can Weewx 4.1 be installed using Python 3 using the *1-Wire *interface?* I'm running that combination: 4.1 with python 3. > If so, any special steps?* For 1-wire? Only the steps that are being refined in the various threads (obviously the latest thread holds the latest updates). If you have owserver running now, there is no (good) reason why it will stop running if you swap to python 3. Mathews owfs.py picks up the the appropriate module seamlessly. I know with certainty that the versions in my fork work. You have a working configuration in weewx.conf so the steps should really be minimal. > I tried following the Installation Guide to install on a test Ubuntu system > but got errors about Cheetah 3 not found (or something like that). Pass. Each distro will have its own quirks as it plays catch up with the python 3 push. For a pi I'd stick to raspbian or whatever they are calling it now - Raspberry Pi OS? > 2. What is the benefit of using Python 3 rather than Python 2 (other than 3 > is supported)? If you have a working install and it's doing what you want then there's probably no reason to change. It's only if you need to do an operating system update, or want to try another skin, weather station, use another data source that you may run into issues, but that's all crystal ball stuff. It's probably not so much that 3 is supported, it's that main stream support for 2.7 has dried up. With a vengeance in some cases. That leaves us playing catch up, but dare I say it ... actually winning! -- Cheers Glenn rorpi - read only raspberry pi & various weewx addons https://github.com/glennmckechnie -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
