This post provides an introduction to the software called wview. Wview is weather station software that allows you to read data from a wide variety of weather stations. It produces graphs, can give you an almanac snapshot, and you can also use it to push data to external websites such as weather underground (www.wunderground.com). And it costs nothing; it is available from sourceforge.net or at www.wviewweather.com. This post will look more at using the GUI to set up the workstation, and using the log files to check on the operation of the software.
Assuming that you have a weather station, then you will want to install the software. The home page of www.wviewweather.com sets out the steps to follow, depending on your Linux distribution. Once you are done installing, it is then a matter of configuring the software.Configuration of the software can be done either by running a script called wviewconfig (you will need to be super user to run this) or by using a web browser. For brevity, this post will show configuration using the web browser only. The CLI option is handy, but it can take some time. The GUI can be started by opening a browser then typing in http:/localhost/wviewmgmt/login.php. The administrator login comes up (as shown in Figure A).

That is wview; an example of free software that is every bit as good as commercial software on the market. It is highly configurable, and can provide you with enough weather statistics to keep you busy for quite some time.
