Cumulus was born in 2003, when Steve Loft decided none of the weather software available suited his needs, so he wrote something that did do what he wanted. | |||
It offers a lot of features, here, in case you are wondering about trying this software, are the key ones: | It offers a lot of features, here, in case you are wondering about trying this software, are the key ones: | ||

* Display of additional sensors | |||

* Direct support for Fine Offset stations (no need for EasyWeather) | |||

This is no longer available as it never worked satisfactorily. While Cumulus 1 uses a "rain counter" and derives everything it reports from that (with some problems and complex code to cope with odd changes in the counter), Cumulus 2 used directly what each weather station was reporting for rain, and tried to adjust that into daily (e.g. 9am to 9am) rainfall; this was not as easy as Steve Loft expected. | This is no longer available as it never worked satisfactorily.

While Cumulus 1 used local time, (with some oddities when daylight saving time started and finished), Cumulus 2 logged everything in UTC, the idea was to avoid issues with time zones, but actually implementing that for Cumulus users all round the world was not as easy as Steve Loft expected. | While Cumulus 1 used local time, (with some oddities when daylight saving time started and finished), Cumulus 2 logged everything in UTC, the idea was to avoid issues with time zones, but actually implementing that for Cumulus users all round the world was not as easy as Steve Loft expected. | ||
Steve Loft felt he wasted a lot of time working on Cumulus 2, as he found using C# code a real struggle. He stopped, and restarted, its development a few times, before finally giving up. In the end, only a small number of users did use it. | Steve Loft designed Cumulus 2, so the units you selected effected how a value was shown, but not how the value was stored. Consequently in Cumulus 2, as all values were stored exactly as output by weather station, you could easily change units for display at any time.
