Cumulus Support

I am gathering data on daily sunshine hours from a separate sensor to my W-8681 weather station. Is there anywhere I can input these figures manually into a Cumulus file that would enable me to graph the results using Cumulus.
Thanks for any info

Daily sunshine totals are logged in dayfile.txt, so you could use the dayfile editor in Cumulus to input them, but Cumulus currently doesn't have any charts for sunshine hours anyway.
