* Each time Cumulus (both 1 and MX) reads records from the weather station it applies any change to the 'total rain count' against today's total in its memory. This "Count" approach has been chosen because different weather stations output different values, and an independent count is a way of working that can be applied for any weather station. | * Each time Cumulus (both 1 and MX) reads records from the weather station it applies any change to the 'total rain count' against today's total in its memory.

**As you will see if you look in [[ | **As you will see if you look in [[diags_folder]], Cumulus stores the 'total rain count' figure at rollover, so by maintaining the current figure it can subtract off the start of day figure to deduce the rainfall today and this is shown on the front screen in Cumulus 1, labelled ''Today''. In Cumulus 1 the '''Edit''' menu gives access to the ''Today's rain'' screen and that provides the ability to edit the start of day figure so that the figure shown for today is correct. Equivalent functionality is provided in Cumulus MX. If there is no rain in a day, the start of day count will be the same at the start of the next day. | ||
**Today's rain is added to the figures (as described above) derived from dayfile.txt for what the front screen in Cumulus 1, labels '''This month''', and ''This year'' (this last figure is the seasonal total, you can choose for it to start on 1 January or any other month). Thus these figures are updated each time Cumulus receives a rain reading from the station (they all include today-so-far), and these figures will not be displayed if Cumulus is unable to read rain information from your station. | **Today's rain is added to the figures (as described above) derived from dayfile.txt for what the front screen in Cumulus 1, labels '''This month''', and ''This year'' (this last figure is the seasonal total, you can choose for it to start on 1 January or any other month).

** The today's total so far at each reading time is also added to the 'recent tag' array allowing total values for the day-so-far at one minute intervals for up to a week ago to be added as web tags to a web template. | ** The today's total so far at each reading time is also added to the 'recent tag' array allowing total values for the day-so-far at one minute intervals for up to a week ago to be added as web tags to a web template. | ||
