Hi.

I am looking into connecting a homey pro to an existing knx installation using the recommended Weinzierl 732 knx ip interface.  
I have a question to get me started. How do you set the proper address for the ip interface so that it connects to the knx bus? My bus starts at address 1.1.3, but the standard address for the interface is 15.15.255. Do I need to change interface address to the same range as the existing knx bus (1.1.x)? And do I need the ETS software to do this?

Thanks in advance.

Best regards
