This LWC2 release is rock solid and amazingly full of features. I have had it running on my server since the day of its release, 31 July, and it has required no attention from me since that date. There is no better weather station interface software available, bar none. Great job Stu!

Lightsoft Weather Center (LWC) is the BMW of Weather Station Software. After finding Davis Instrument's WeatherLink for Mac utterly unsatisfactory, I investigated all the Mac Weather Station software offerings about a year ago. Even then, LWC was head and shoulders over its competition. Version-2 incorporates a complete redesign of the architecture to vastly improve performance and reliability. It also has some "gotta-have" enhancements that leaves even its PC competition in its wake.

Even the development version of LWC-2 was stable for weeks at a time and was very forgiving of Weather Station connectivity issues I was having for a while. LWC has very robust and reliable Internet upload capabilities. It not only does the "required" upload to Weather Underground and CWOP, but it provides you with detailed information about how the processes are going. There is even a supplied AppleScript that will provide Growl announcements should your Internet services have a problem.

Where LWC really shines over the competition is in its graphing capabilities. You can create very complex graphs using multiple sources of weather data. These can be used for something as complex as graphing parameters related to the onset of precipitation or as basic as when to open and close your windows by comparing indoor and outdoor temperature. Folks who have custom weather websites can display these custom graphs on their website to provide unique information to their website viewers that simply isn't possible using other software.

LWC is built for Mac only using Apple's Cocoa development environment. So it has no baggage for Windows portability and no legacy code that reduces efficiency. It also takes advantage OS-X capability of multi-threaded applications. That means LWC will really scream on the fastest Macs with multiple cores and/or processors, and because of OS-X's superior resource management, it won't hog older machines unnecessarily. LWC runs fine on older Mac so that you to "recycle" an old Mac as a dedicated Weather Station manager. However, it also is a "good citizen" with other Macintosh applications. So you can run LWC on your Mac workstation and have it seamlessly take care of your Weather Station even if you run CPU hogs like graphics applications. That way you can keep an eye on the weather no matter how you use your computer for on a daily basis.

LWC has been a commercial product for several years and an enthusiastic community of loyal users has sprung up around it. If you have a question about LWC or weather matters in general, someone on the LWC forum is bound to have at least a helpful pointer to get you unstuck. That's really, really important since weather stations are complex and cantankerous beasts and technical support is hard to find and rarely all that helpful. The LWC forum is by itself a reason to use LWC, but its very existence is testimony to how good LWC really is. Like the Mac itself, it takes an outstanding product to make people passionate about it. LWC is truly such a product. If you have Mac, don't settle for anything less!

Version 2.1 of Lightsoft Weather Center (LWC) adds a new plug-in architecture that will allow 3rd party developers to extend LWC for specific needs. Whether the task is computing agricultural watering schedules or estimating drag racing bracket times, programmers can simply extend LWC instead of reinventing the wheel.

End users get some solid improvements with 2.1, including support for the IP version for the Davis Vantage data logger. They also get a really nifty active banner generator that allows you create a web banner with current weather conditions to place at the bottom of a web page or rich-text email. This latest release as it all from major architecture improvements to really fun accessories!

A mon sens, le meilleur et le plus complet logiciel de gestion de station météo sur Mac. Il permet de récupérer les données de sa station, de les gérer et les stocker, mais aussi de les publier sur Internet, soit sur son site personnel (avec graphiques et jauges), soit sur Wunderground ou le CWOP.
Enfin, son plus grand avantage est d'être soutenu par un développeur hyper-réactif et une solide communauté d'utilisateurs.

A great product.

Works flawlessly with my La Crosse WS-2355 weather station and is very configurable to suit individual requirements.
I love its ability to monitor two extra stations via the internet (Wundergound etc.) thereby giving you the ability to get the "bigger picture" of weather in your area. The AppleScripts that come with the product are ideal for setting up alarms and Growl notifications of weather events, these are in addition to the alarms that are already configurable within the programme.

Great job

Bass Lake Weather

As the operator of the official National Weather Service reporting station for Bass Lake Ca. in the Sierra Nevada mountains, I needed the most reliable weather station software I could find to handle the data from my Davis Vantage Pro 2 hardware. Something that could run unattended for weeks and months at a time. That had the capability to not only handle the typical uploading of my station's weather data to the NWS and other weather data sites, it needed to be able to post automated weather alerts to my station web site in real-time as well as handling a host of other duties. LWC answered that call in spades!

Not only does LWC provide more specialized features than any other weather software currently available for Mac or PC, the fact that it is a native OS X application means that it can take full advantage of the Macintosh computer platform, which has proven itself to be the most stable and reliable computer platform around for unattended operation.

With the release of LWC version 2, Lightsoft has taken the best features from the original LWC product and built upon that solid foundation, creating a product that does more yet requires much less attention from the station operator. This is precisely what a station like mine needs to be able to maintain uninterrupted 24/7 operation with no lost data and full automation capabilities to run everything reliably for months at a stretch, with no freezes. hangs or other annoying behaviors.

There are few software products that can justify the purchase of the computer platform to run it, but LWC 2 is just such a product. Owners of popular weather station hardware that have been struggling with the low reliability of Windows based systems should seriiously consider replacing their PC based system with a Mac Mini or Macbook running LWC 2. The difference in features, performance and reliability will blow your mind!

In conclusion, I can't recommend LWC 2 highly enough. I wouldn't trust my weather data to anything else.

This is the best software on the market for both Macs and PCs. There is a significant amount of features built in and now has the ability for custom graphics. The authors are responsive to your needs and usually answer your question posted on their forums. I have LWC2 installed and it simply works....it works all the times.

All I can say is, thank you!

It's great to have a Mac option for my Davis Vantage Pro.

Can't argue about the price.
