=== Cumulus 3 aka MX ===
=== Cumulus 3 aka MX ===
[[Cumulus MX]] is newer, and still being actively developed, it will run on a number of operating systems and has the advantage that it consists of an engine that reads the AWS, does the calculations, and creates a web server. There is then a separate user interface that runs in this web server, and lets you see a number of dashboard type web pages and edit settings. This separate user interface can run on any device connected to your local network (LAN) or wifi, as it just just needs a private link to the device running MX. Despite MX being more complicated to get to know, it does offer more features and can connect to more AWS than Cumulus 1. This is not the place to list all extra features, but it can output to a database, it maintains its file of extremes for a month and year beyond the end of those periods, and adds the ability to process a file only at end of each day.

=== Should I use Cumulus 1 or Cumulus 2 or Cumulus 3 (MX)? ===
Steve Loft (who originated all 3 versions) had no recommendations one way or the other. However, since he focussed on enjoying retirement and withdrew from involvement in Cumulus, a lot has changed.
Now newcomers should probably choose Cumulus MX, but read on if you are not sure.
Cumulus 1 is a finished version, and because the development environment is obsolete no further changes are possible. That said there have been two recent patches to the screen interface, allowing dates from 2021 to 2030 to be selected in drop downs, but the core code will never change. Cumulus 1 is reliable and has more functionality to cope with problems if your weather station set-up may experience problems. However, it does not support some new weather station models, and it will only run  on a Microsoft Windows device, so those two facts may imply you cannot use it! Although there remains some expertise with Cumulus 1 established users, any newcomer may prefer to choose a MX as that has more technical support available.
Cumulus 2 explored an improved data approach using UTC and having better handling of rainfall. Although it was hoped it would make enhancement easier, and allow use of alternative languages possible, it proved too complicated. and has been abandoned and is no longer available, so if you don't already have it hard luck.  Subsequently, some of the developments in Cumulus 2 were ported into new version 1.9.0, and remain in final Cumulus 1.9.4 from where they were in turn ported to Cumulus MX. So whichever of the two versions still available you choose, you are benefiting from work done for Cumulus 2.
Cumulus 3 is live and is still being improved. It is more often known as [[Cumulus MX]]. It is using a different architecture (partly inspired by Cumulus 2), it provides some enhancements in functionality and will run on a range of platforms. It can be used in a production system as it has good reliability,  but perhaps should be avoided in a few rare cases where people's systems are not very reliable. Initially MX lacked several key parts of the functionality in Cumulus 1, but the number of such facilities continues to decrease as Mark Crossley is adding missing functionality.
