Python 2 and Python 3 keep separate libraries. What this means is that if something is installed for Python 2, it will not be available for Python 3. You must re-install for Python 3.
If you review the install instructions <https://github.com/matthewwall/weewx-mqtt/blob/master/readme.txt> for weewx-mqtt, you'll see that it tells you that for Python 3, you'll need: *sudo pip3 install paho-mqtt* This will install and make available a Python 3 version of paho-mqtt. -tk On Mon, Sep 14, 2020 at 10:29 AM Michael Sanphillipo <sanphill...@gmail.com> wrote: > I get the following error after changing from python 2 to 3.
