I don't have those sensors here so I can't say these work, but do these tags get the data you're seeking?
STAT$DAILYET$
STAT$MONTHLYET$
STAT$YEARLYET$
If so, just insert these tags into the template as follows:
For example, the Yesterday panel would be:
Find the line that says <div class="yestextremes" id="panel0">
and insert the following, e.g. right after the Rain Yesterday line.
<p>STAT$DAILYET$</p>
and it should look like this:
<div class="yestextremes" id="panel0">
<p> High: STAT$TEMPERATURE:MAX:YESTERDAY$ TEMPUNITS$ at STAT$TEMPERATURE:MAX:YESTERDAY:TIME$</p>
<p> Low: STAT$TEMPERATURE:MIN:YESTERDAY$ TEMPUNITS$ at STAT$TEMPERATURE:MIN:YESTERDAY:TIME$</p>
<p> High Heat Index: STAT$HEATINDEX:MAX:YESTERDAY$ TEMPUNITS$ at STAT$HEATINDEX:MAX:YESTERDAY:TIME$</p>
<p> Low Windchill: STAT$WINDCHILL:MIN:YESTERDAY$ TEMPUNITS$ at STAT$WINDCHILL:MIN:YESTERDAY:TIME$</p>
<p> High Humidity: STAT$EXTHUMIDITY:MAX:YESTERDAY$ % at STAT$EXTHUMIDITY:MAX:YESTERDAY:TIME$</p>
<p> Low Humidity: STAT$EXTHUMIDITY:MIN:YESTERDAY$ % at STAT$EXTHUMIDITY:MIN:YESTERDAY:TIME$</p>
<p> High Dew Point: STAT$DEWPOINT:MAX:YESTERDAY$ TEMPUNITS$ at STAT$DEWPOINT:MAX:YESTERDAY:TIME$</p>
<p> Low Dew Point: STAT$DEWPOINT:MIN:YESTERDAY$ TEMPUNITS$ at STAT$DEWPOINT:MIN:YESTERDAY:TIME$</p>
<p> High Pressure: STAT$PRESSURE:MAX:YESTERDAY$ PRESSUREUNITS$ at STAT$PRESSURE:MAX:YESTERDAY:TIME$</p>
<p> High Windspeed: STAT$WINDSPEED:MAX:YESTERDAY$ WINDSPEEDUNITS$ at STAT$WINDSPEED:MAX:YESTERDAY:TIME$</p>
<p> Rain: STAT$RAIN:TOTAL:YESTERDAY$ RAINUNITS$</p>
<p>STAT$DAILYET$</p>
</div>
You can follow a similar procedure for the Monthly and Yearly panels as well.
