Hi,
I originally sent this to the author but posting here as well. I am trying
to use the $daylight tag to display the daylight average of UV and
Radiation values. It works fine in the current day and yesterday templates,
but generates an error when I try to use accumulator code for the week,
month and year templates, and the month and year report templates. I am
using the NeowWX-Material skin with WeeWX 4.8 on a RPi 4B 4GB running
Bullseye.
Code:
#from weewx.units import ValueTuple, ValueHelper
#for $dd in $week.days
#set $light=$daylight(timestamp=$dd)
#set $dayradiation=$dd.$light.radiation.sum.raw <-- this is where it fails
#set $dayradiationacc=$dayradiationacc.raw+$dayradiation.raw
#end for
#set $dayradiationavg=$dayradiationacc.raw/$week.days
#set
$dayradiation_vh=ValueHelper(ValueTuple($dayradiationavg,$unit.unit_type.radiation,'group_radiation'),formatter=$station.formatter)
...
<div class="row">
<div class="col-3 text-muted font-small">
$dayradiation_vh <br>
$Extras.Translations[$Extras.language].avg
</div>
<div class="col-6">
<h4 class='h2-responsive
'>$week.radiation.energy_integral.kilowatt_hour_per_meter_squared</h4>
</div>
<div class="col-3 text-muted font-small hi-text">
$week.radiation.max <br>
($week.radiation.maxtime.format($Extras.Formatting.datetime))
</div>
</div>
Error:

Any help, pointers or neater code would be appreciated!
