@Joe13, I am new to DzVents too ... but it is a great opportunity to learn
Have a look into the Domoticz installation folder, can't remember now exactly where but there is a sub-folder with interesting examples, when you start reading these examples you may have a better overall understanding of how DzVents works.
Their wiki is also very usefull:

Have fun @Joe13 ...
