Revision as of 11:56, 17 January 2013
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 can create missing data from the newly created monthly log files, but you still may wish to insert breaks at rollover time in your raw EasyWeather table, possibly adding calculation of maximua or minima to such meteorological day groups, so you can scan though each day to check what has been created in dayfile.txt and edit as required.
Using EasyWeather data for testing purposes
As an alternative to above, you can extract the observations directly from the Fine Offset database (easyweather.dat can be read like any text file by a text file editor like Notepad or by a database file viewer).
Steve has contributed the following to the forum (http://sandaysoft.com/forum/viewtopic.php?f=4&t=4344) see that forum thread for more details:

This page describes in some detail the data records produced by the Fine Offset device
Thanks to Jim Easterbrook for all his work on pulling this data together http://www.jim-easterbrook.me.uk/
