Go to http://www.perl.de (when they fixed the PHP error which cur­rent­ly shows up) and search for a weath­er sta­tion at around 100 EUR (99,xx EUR). If it has a USB port and they tell about some Easy­Weath­er soft­ware, it is the right one. If you go to the ven­dor home­page and have a look at the pro­fes­sion­al sta­tions, it is one of the 2 touch­screen ones (I do not know the dif­fer­ence between them).
