If you want to setup your own installed YoWindow to display the weather of Veresegyház, I suggest you to set the location to
Gödöllő under Location - Add... and
Write Veresegyház to the Name at
Location - Location Properties. Also tick the
Load weather from personal weather station:. Click on the setup button
and write http://captainbc.hu/wov/yowindow.xml to URL.
