and now i tried it using LogTemp (http://www.mrsoft.fi/ohj01en.htm)

but it keeps telling me: "1-Wire network does not exist"

how can i troubleshoot this?

You can use this circuit as 1 Wire to RS232 Interface.
I can provide you the PCB files if you plan to make your own..

is it possible to connect the 1-wire devices from hobby-boards.com to the RFXsensor and use the value in HS?
