You can add more temperature sensors to your existing schema. Follow the directions in the section *Adding a new type to the database* in the copy of the Customizing Guide *that came with your 3.9.X version* (Version 4.x uses a different method).
If you wish to use Python 2 on buster, use the Debian 9 (squeeze) instructions: *wget -qO - http://weewx.com/keys.html <http://weewx.com/keys.html> | sudo apt-key add -wget -qO - http://weewx.com/apt/weewx-python2.list <http://weewx.com/apt/weewx-python2.list> | sudo tee /etc/apt/sources.list.d/weewx.listsudo apt-get updatesudo apt-get install weewx* -tk On Sun, Jun 21, 2020 at 10:44 AM Michael Form <maf.01...@gmail.com> wrote: > Tom: > > Thank you for your response.
