EasyWeather Format

Many of the entry level weather stations can be classified as "EasyWeather" or "FineOffset"; they are rebadged or generic models of the device produced by FineOffSet Electronics


The software shipped with the device is EasyWeather and while it peforms its role of reading and storing data from the weather station, it is quite limiting and inflexible.


Of course, most users switch to Cumulus and stop using EasyWeather.


Simply for reference, below are some useful technical links on the EasyWeather format


The File Format

Easy weather stores all its data in easyweather.dat. The file format for this has been described in detail here

Transferring data from EasyWeather to Cumulus

If you need to import EasyWeather data from a period before you started using Cumulus, then close Cumulus and run EasyWeather, in that use the History option on the Record menu.

  • Select 'user defined' in Search Conditions box. Select a start time before you got your weather station, leave end time at default of today.
  • Click Export button, tick Header, choose as Separator: the symbol that is used to separate fields in your Monthly log files.
  • Click Export button below the separator, complete the 'Save as ...' for a text file, and wait a couple of minutes (depending on size of file).
  • Open resulting file in a text editor and see hints in Monthly log files on how to convert between formats.
  • For dayfile.txt, you will need to use a spreadsheet to calculate maximum, minimum or average values as required from grouping the EasyWeather table by Meteorological days (i.e. group break is at your rollover time). The times of maxima and minima can be derived by spreadsheet lookup functionality if you are lucky (but that works best for ordered data)! Otherwise, find them from the individual records or monthly logs.
