Hi
I'm trying to install the Cumulus Realtime files using this description:
realtime.txt, realtime.xml and sunbird.txt copied to the skins folder
xsearch.py copied to the /usr/share/weewx/use folder (see attached
xsearch.py)
My skin.conf:
[CheetahGenerator]
search_list_extensions = user.xsearch.MyXSearch,
user.forecast.ForecastVariables
[[[Realtime]]]
template=realtime.txt.tmpl
[[[Realtime_xml]]]
template=realtime.xml.tmpl
[[[Sunbird]]]
template=sunbird.txt.tmpl
After restarting weeWX, I get this error:

I'm using weeWX version 3.7.1
Any ideas?
Thanks

"""Example of how to extend the search list used by the Cheetah generator.
This search list extension offers two extra tags:
'alltime': All time statistics.
For example, "what is the all time high temperature?"
'seven_day': Statistics for the last seven days.
That is, since midnight seven days ago.
To use it, modify the option search_list in your skin.conf configuration file,
adding the name of this extension. For this example, the name of the extension
is examples.xsearch.MyXSearch. So, when you're done, it will look something
like this:
[CheetahGenerator]
search_list_extensions = examples.xsearch.MyXSearch
Note that if your file skin.conf is from an older version of Weewx, this
section may be named [FileGenerator]. It will work just fine.
You can then use tags such as $alltime.outTemp.max for the all-time max
temperature, or $seven_day.rain.sum for the total rainfall in the last
seven days.
