I'm still struggling with this. Here's the updated code: #errorCatcher Echo #from weewx.units import ValueTuple, ValueHelper #set $dayradiationacc=0 #for $dd in $week.days #set $light=$daylight(timestamp=$dd) #set $dayradiation=$light.radiation.sum.raw #set $dayradiationacc=$dayradiationacc+$dayradiation #end for #set $dayradiationavg=$dayradiationacc/$week.days #set $dayradiation_vh=ValueHelper(ValueTuple($dayradiationavg,$unit.unit_type.radiation,'group_radiation'),formatter=$station.formatter)
And the error: Jan 28 13:20:28 weather weewx[625144] ERROR weewx.cheetahgenerator: Evaluation of template /etc/weewx/skins/neowx-material/week.html.tmpl failed with exception '<class 'TypeError'>' Jan 28 13:20:28 weather weewx[625144] ERROR weewx.cheetahgenerator: **** Ignoring template /etc/weewx/skins/neowx-material/week.html.tmpl Jan 28 13:20:28 weather weewx[625144] ERROR weewx.cheetahgenerator: **** Reason: unsupported operand type(s) for +: 'float' and 'NoneType' Jan 28 13:20:28 weather weewx[625144] ERROR weewx.cheetahgenerator: **** Traceback (most recent call last): Jan 28 13:20:28 weather weewx[625144] ERROR weewx.cheetahgenerator: **** File "/usr/share/weewx/weewx/cheetahgenerator.py", line 348, in generate Jan 28 13:20:28 weather weewx[625144] ERROR weewx.cheetahgenerator: **** unicode_string = compiled_template.respond() Jan 28 13:20:28 weather weewx[625144] ERROR weewx.cheetahgenerator: **** File "cheetah__etc_weewx_skins_neowx_material_week_html_tmpl_1674912028_8195086_18355.py", line 930, in respond Jan 28 13:20:28 weather weewx[625144] ERROR weewx.cheetahgenerator: **** TypeError: unsupported operand type(s) for +: 'float' and 'NoneType' I'm sure there must be an easy way to do this, I need to calculate the average UV index and solar radiation based on daylight hours only.
