*If you have just restarted Cumulus, and encounter multiple rogue readings in the catch-up from the station logger, one possibility is to stop Cumulus and find the backup files that it took when you started it up (or just after the previous roll-over time), copy those files into the data folder, overwriting the ones that are there, then when you start it up again it could sort itself out. The purpose of the backup files is to allow Cumulus to be 'rewound' to a particular point in time. It simulates the situation where someone had closed Cumulus down at that point, and is only now starting it up again, and needs data to be downloaded from the station's logger to catch up to the present time.
The [[Diags]] log often contains useful information for sorting out what has been read, which values have been ignored, and which highs or lows may have been updated incorrectly. Note that automatic backups are made just after roll-over time because restarting Cumulus when there are no logger records to read before roll-over has been known to cause problems.
== I get very large amounts of rainfall shown, or other high readings ==
Fine Offset stations have a habit of producing unbelievable readings, and Cumulus filters many of these out automatically. You can also use the 'spike removal' settings on the calibration page, and Cumulus will then filter out large changes in readings. Please read the help for how to use these settings. Another possible explanation is that you have chosen the wrong station type in the Cumulus station settings. You should only select the "Fine Offset with UV/Light sensor" type if your station actually has SENSORS for these. Your station may have solar CHARGING, but this is not the same as having a solar SENSOR, and so you should choose the "Fine Offset (WH1080 etc)" type. Typically, stations which do have solar SENSORS have a model number which starts with a '3', e.g. WS3080, and stations without solar sensors start with a '1' or '2'. Selecting the wrong type of station will cause Cumulus to misinterpret the logger data read from the station and hence incorrect readings will result.
== My station invented some rain that didn't really occur, and I want to set it to zero (or some other figure) ==
