The files today.ini and yesterday.ini are used by Cumulus to store Highs and Lows for each of the two days. These files are located in the Cumulus Data folder.

The today file is written to throughout the current day as new High or Lows for the day at reached. At the end of a day (either midnight, or 9am depending on your configuration), the today.ini file is rolled-over to become yesterday.ini and a new today.ini is created.

If you close down and restart Cumulus during the day it will read these files at startup.

Normally you would not need to edit these files, however rarely you may wish to edit the rain data if there has been a quirk in your weather station reporting during the day and the figure is abnormally inflated.

Note: If you do edit either of these files, you must close Cumulus down first!
