Hi Chris, Sorry it took so long, I started a new job a few weeks ago, and hobbies have taken a back seat! Let me start by saying that all the information, and better descriptions of what is happening can be found in the Weewx Customization Guide that TK and the guys have put together. http://weewx.com/docs/customizing.htm
All of the back end is contained in one file, On my system \usr\share\weewx\user\ArchiveSearch.py Look at Defining New Tags <http://weewx.com/docs/customizing.htm#defining_new_tags> in the docs, the similarities should be immediately apparent. This then get's included in the search list extensions in skin.conf. You can then include your new tags in your *.tmpl files, to be generated each time the generator runs. First the ArchiveSearch.py: I removed most of the comments that are in the documentation for the sake of brevity. It is worth noting that you may need to install python relativedelta on your system for this to work. *import datetime* *import time* *from dateutil.relativedelta import relativedelta* *from weewx.cheetahgenerator import SearchList* *from weewx.tags import TimespanBinder* *from weeutil.weeutil import TimeSpan* *from weeutil.weeutil import archiveDaySpan* *from weeutil.weeutil import archiveWeekSpan* *from weeutil.weeutil import archiveMonthSpan* *from weeutil.weeutil import archiveYearSpan* *class ArchiveSearch(SearchList): # 1* * """My search list extension"""* * def __init__(self, generator): # 2* * SearchList.__init__(self, generator)* * def get_extension_list(self, timespan, db_lookup): # 3* * """Returns a search list extension with two additions.* * Parameters:* * timespan: An instance of weeutil.weeutil.TimeSpan.

Here is a snippet from my Year tab. You will see how the new tags are being used, again i removed some bits for brevity. <div class="card" > <h1><i class="fa fa-history m-rot" ></i> History: Last Year to Date</h1> <div> <table class="tablespacer"> <tr><td colspan=3><h3>Outdoor Conditions</h3></td></tr> <tr><td>High Temperature</td><td>$last_year_to_date.outTemp.max</td><td>$last_year_to_date.outTemp.maxtime</td></tr> <tr><td>Low Temperature</td><td>$last_year_to_date.outTemp.min</td><td>$last_year_to_date.outTemp.mintime</td></tr> <tr><td>Average Temperature</td><td>$last_year_to_date.outTemp.avg</td><td></tr></tr> <tr><td>High Heat Index</td><td>$last_year_to_date.heatindex.max</td><td>$last_year_to_date.heatindex.maxtime</td></tr> <tr><td>Low Wind Chill</td><td>$last_year_to_date.windchill.min</td><td>$last_year_to_date.windchill.mintime</td></tr> <tr><td>High Dewpoint</td><td>$last_year_to_date.dewpoint.max</td><td>$last_year_to_date.dewpoint.maxtime</td></tr> <tr><td>Low Dewpoint</td><td>$last_year_to_date.dewpoint.min</td><td>$last_year_to_date.dewpoint.mintime</td></tr> <tr><td>High Humidity</td><td>$last_year_to_date.outHumidity.max</td><td>$last_year_to_date.outHumidity.maxtime</td></tr> <tr><td>Low Humidity</td><td>$year.outHumidity.min</td><td>$last_year_to_date.outHumidity.mintime</td></tr> <tr><td>High Barometer</td><td>$last_year_to_date.barometer.max</td><td>$last_year_to_date.barometer.maxtime</td></tr> <tr><td>Low Barometer</td><td>$last_year_to_date.barometer.min</td><td>$last_year_to_date.barometer.mintime</td></tr> <tr><td colspan=3><h3>Wind and Rain</h3></td></tr> <tr><td>High Wind Speed</td><td>$last_year_to_date.wind.max $last_year_to_date.wind.gustdir</td><td>$last_year_to_date.wind.maxtime</td></tr> <tr><td>Average Wind</td><td>$last_year_to_date.wind.avg</td><td></td></tr> <tr><td>RMS Wind</td><td>$last_year_to_date.wind.rms</td><td></td></tr> <tr><td>Vector Average Speed</td><td>$last_year_to_date.wind.vecavg</td><td></td></tr> <tr><td>Vector Average Direction</td><td>$last_year_to_date.wind.vecdir</td><td></td></tr> <tr><td colspan=3><h3>Indoor Conditions</h3></td></tr> <tr><td>High Inside Temperature</td><td>$last_year_to_date.inTemp.max</td><td>$last_year_to_date.inTemp.maxtime</td></tr> <tr><td>Low Inside Temperature</td><td>$last_year_to_date.inTemp.min</td><td>$last_year_to_date.inTemp.mintime</td></tr> </table> </div> </div> Before you do any of this to your system, I would take an hour and read through the *entire* customization guide. You may not understand everything as you read it, but it will help you. I asked many stupid questions that were covered in the guide when I was getting started.
