Hi Tom I am again disturbing you. As I said I managed it to summarize my energy production with your hint, but it is still not satisfiying my wish. Here my code to summarize the production of a month: #set $month_total=0 #for $day in $month.days <tr><td>$day.dateTime.format("%A %d.%m.%y")</td><td>$day.electric_ed.last</td><td> #if $day.electric_ed.last.raw is not None #set $month_total += $day.electric_ed.last.raw #end if #end for #set $month_total = $month_total / 1000 #set $month_total = "%.2f" % $month_total <tr><td>Total des Monats </td><td>$month_total KWh</td><td>
starting the sum with: #for $day in $month.days starts the first day of a month, what I need is to set the starting time one month back from today. I tried to set the starting day with $month($months_ago=1) #for $day in $month($months_ago=1).days gives an error: TypeError: month() got an unexpected keyword argument 'months_ago' As the graphic shows the values of the last week, rsp. the last month I would like to present in the table also the values of the last week, resp. the last month, not the values starting from monday or the the 1. of a month. So how do I set the correct start day for the summarisation? Regards Marco -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
