|Add this line to cumulus.ini [Station] section

Cumulus (1 and MX) has a configurable threshold for the maximum feasible amount of rain between updates (i.e. within 48-seconds on Fine Offset stations without solar, 60 seconds on those measuring solar), set in units of count of tips.

Default=30 tips, as each tip represents 0.3mm this is equivalent to 9 mm or just over a third of an inch in 48 seconds.

This setting affects rain rate, rain last hour, rain so far today (and what is recorded in today.ini/dayfile.txt), but does not affect the web tag <#r24hour>.

|EWmaxRainRate=999

|This is set in the spike removal frame on the Calibration settings screen off the configuration menu.

A rain rate 'spike removal' filter, ''changes in calculated value'', between one calculation and the next, greater than the value specified here (set in calibration screen of configuration menu) will be ignored by Cumulus when it calculates the rain rate.

Cumulus ignores this parameter for other makes of weather station (they supply a rain rate to Cumulus). The default value of '''999''' also effectively makes Cumulus ignore spike removal.

|EWminpressureMB=900

|Add this line to cumulus.ini [Station] section

Cumulus will ignore all pressure readings from the station that are less than this value (units are always hPa/millibars)

 

|EWmaxpressureMB=1200

|Add this line to cumulus.ini [Station] section

Cumulus will ignore all pressure readings from the station that are greater than this value (units are always hPa/millibars).
