Little obsessive possibly but I like my website stats to update every 15 minutes at 00, 15, 30 and 45 past the hour. Currently the only way I can do that is by remembering to restart Cumulus at either 00, 15, 30 or 45. Not impossible to do that - but be nice if I didnt have to.
Days since last rainfall
I know the screen shows when the last rainfall was. Be a nice touch if we could say "x" days since last recorded rainfall.
Excellent software - installed out the box (as it were) and run fault free for the last six weeks.
