'pyephem' / extended almanac data

[f4n...@gmail.com]

When I start my weewx sdr instances, I always see this in the log:

weewx.engine: 'pyephem' not detected, extended almanac data is not available

which extended almanac data am I missing and how can I fix it?

In terms of what you are missing without pyephem you might want to read the Almanac section in the Customization Guide. Practically though, if you are running something like the Seasons skin you will not see any detailed Sun and Moon rise/set/position details. For other skins it depends on the skin, but without pyepehem you will only have access to tags for sun rise/set and moon phase and moon % fullness, any other $almanac tag will not be available.

How to install pyephem - the WeeWX setup.py install instructions contain instructions for installing pyephem for your OS, just look in the appropriate tab under '1. Install prerequisites' for the pyephem/ephem install command applicable to your OS.

In a Debian derivative you can just use:
sudo apt install python-ephem
or
sudo apt install python3-ephem
