Thanks for the feedback.
Regarding the weewx version required, there is no weewx version which would
support the extension at this time. Have you ever patched weewx code in the
installer? I suppose I could write fallback code, but it makes the extension
just a little bit 'heavier'.
Regarding then Config in the installer, I could not see how to include Config
comments inline. Is it possible to include Config comments via the inline
Yes, the extension installs well via wee_extension.
