Hello!
I’m new to Home Assistant an I have a KNX-Installation at home.
I have one KNX Interface in the Main-Building and another one for the garden.
These Interfaces are both IP-Interfaces, which are in the same subnet.
Unfortunately I can add only one of these to the configuration.yaml.
Is it possible to add another one? I couldn’t find any help in the documentation.
Thank you.

It’s not possible with the standard KNX Integration.
Are these 2 completely separate installations with separate ETS projects?
You could change the interfaces for Routers and even have a combined installation with 2 areas. Or connect them via Knx cable.
Maybe knxd can be used to link 2 interfaces too.
You could maybe also use the xknx custom component for the second installation (this is normally for development and has its own platform name) - not really sure if that works.
Yes, these are two installations with two ETS projects.
OK, then I have to check how I can use Routers.
Thanks for your help!
Just fyi the HA knx integration doesn’t support KNX secure. So you can get Routers instead of the Interfaces that support knx-secure, but you would have to turn secure off completely.
Another way would be to use routers with secure and 1 interface without. You could then tunnel into the interface and communicate with the second area through the routers with knx-secure connection.
In both cases you will have to avoid using the same GAs for different purposes on the 2 lines.
Also Routers are quite expensive (~250€ for one) - so if it is not critical for you I would try to use two knxd instances that connect to your tunnelling interfaces and provide a multicast server.
