=Fine Offset Weather Stations=
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 [http://www.foshk.com/en/products/show.asp?id=41 FineOffSet Electronics]
The software shipped with the device is EasyWeather (or EasyWeatherPlus for some models) and while it peforms its role of reading and storing data from the weather station, it is quite limiting and inflexible. Of course, if you are reading this you have probably already switched to Cumulus and
==Note on Models==
Fine Offset manuafactured models are sold under various rebadged names and the specification of models may vary, but [http://www.foshk.com/ their website] suggests the following models have PC interfaces:

Do note that WH108x series display rolling 24 hour rainfall on console, WH308x series show rainfall since midnight on console.
'''Note that transmission frequencies, and protocols may vary for the same model''' with a different country of sale, for different dealers (or by how rebadged), and/or by date of manufacture. Although wind measuring and rain measuring sensors should be interchangeable between models (despite some design variations), the thermonmeter/hygrometer/transmitter unit and console have to be replaced as a pair because of their specific frequencies and protocols.
==Memory Map==
This [http://www.jim-easterbrook.me.uk/weather/mm/ page] describes in some detail the data records produced by the various Fine Offset devices (WH1080, WH1081, W-8681, WH3080, WH3081 etc.). The weather station's history is stored in 4080 times 16-byte records for models without UV/solar detectors and 3264 times 20-byte records in the 3080/3081 models with the UV/solar detector.
Thanks to Jim Easterbrook for all his work on pulling this data together

=The File Format=
The following are some useful technical links on the EasyWeather format
==EasyWeather.dat==
Fine Offset weather stations, without solar or UV measurements, store all the observations in easyweather.dat when the EasyWeather software is running. The file format for this has been described in detail [http://www.jim-easterbrook.me.uk/weather/ew/ here]. (You can view ''easyweather.dat'' like any text file either using a text file editor like Notepad or by using a database file viewer).
==Station configuration screen: Using 'EasyWeather.dat' file as current input==
You might want to run EasyWeather software, perhaps for testing purposes, and use its output file as the input for Cumulus software on a short term basis.
Remember, it is better to select the ''Fine Offset (WH1080 etc)'' input (this reads observations by most models directly via USB without EasyWeather software) for normal operational purposes (again see Cumulus help for station configuration screen) as that allows Cumulus to do more. If your station model measures UV and solar light intensities, the recommended input selection is ''Fine Offset with UV/Light sensor''.
''Amended by [[User:Sfws|Sfws]] 14:17, 28 March 2013 (UTC) on basis of information in help and support forum:'' As an alternative to the bulk transfer above (that was for transfer of historic observations), Cumulus at all versions has the option to ''read the latest'' observations ('''the last line only''') directly from an easyweather.dat file (see Cumulus help for how to fill in the station configuration screen) and process these. From version 1.9.4 build 1071 onwards Cumulus assumes 'easyWeatherPlus.dat' format if ''extra sensors'' ticked and 'easyweather.dat' format if that is unticked.
==Usage of easyweather.dat fields for Cumulus input of latest record:==
''Steve Loft has contributed the following:'' People with non Fine Offset stations may wish to create data in this format for input to Cumulus.
See the forum (http://sandaysoft.com/forum/viewtopic.php?f=4&t=4344) for more details: Cumulus does not see any station date and time fields when reading a Fine Offset weather station received transmission or processing readings in its memory via USB.
Note when reading easyweather.dat (or equivalent format input), Cumulus does read the station originated date and time fields, and checks that they have changed before using new data from the file.
Here's the format of the 'easyweather.dat' file, with the fields Cumulus uses in bold:
0 - Record no; 1 - Transfer date; 2 - Transfer time; '''3 - Reading date'''; '''4 - Reading time'''; 5 - Interval;
24 - rain last 24 hours; 25 - rain last 7 days; 26 - rain last 30 days; '''27 - rain last year''' (used as rain 'counter' to determine other totals)
