This is a good question, and it took me a while to figure out how to work
around the limitations of pyephem. Try this:
1. Put the following in user/extensions.py:
import ephem
eros = ephem.readdb("433
Eros,e,10.8276,304.3222,178.8165,1.457940,0.5598795,0.22258902,71.2803,09/04.0/2017,2000,H11.16,0.46")
ephem.Eros = eros
2. Modify the WeeWX module weewx/almanac.py so that the function
_get_ephem_body() looks like this:
def _get_ephem_body(heavenly_body):
# The library 'ephem' refers to heavenly bodies using a capitalized
# name. For example, the module used for 'mars' is 'ephem.Mars'.
cap_name = heavenly_body.capitalize()
# If the heavenly body is a star, or if the body does not exist, then an
# exception will be raised. Be prepared to catch it.
try:
ephem_body = getattr(ephem, cap_name)()
except AttributeError:
# That didn't work. Try a star. If this doesn't work either,
# then a KeyError exception will be raised.
ephem_body = ephem.star(cap_name)
except TypeError:
ephem_body = getattr(ephem, cap_name)
return ephem_body
You are adding the two highlighted lines.
3. Then use this in your template:
$almanac.eros.rise
for when it rises, etc. (treat it just like any other planet).
Double check the answer. I'm not 100% confident this will work. If it does,
I'll add the changes for weewx/almanac.py to the code base.
