Weinzierl Engineering

Weinzierl Engineering builds the KNX IP interfaces, routers, and protocol stacks that a large part of the KNX industry runs on, including the reference hardware most Home Assistant KNX installs are tunnelled through. The devices are one module wide, powered from the bus, and reached by Home Assistant over KNXnet/IP.

Hardware availability

Weinzierl sells through KNX distribution rather than retail. The interface and router families run secure and non-secure variants side by side under adjacent article numbers, and the difference is not visible on the DIN rail, so specify by article number: 731 and 751 are the non-secure interface and router, 732 secure and 752 secure the KNX Secure ones.

KNX IP Interface 732 secure

The 732 secure is Weinzierl's KNX Secure IP interface, one module wide and powered from the bus. Eight simultaneous KNXnet/IP tunnels and AES-128 KNX IP Secure make it the interface to specify when Home Assistant, ETS, and a visualisation all need to hold a connection to the same line at once.

KNX IP Router 752 secure

The 752 secure routes KNX telegrams between lines over the LAN as a fast backbone, and doubles as a KNX Secure interface with up to eight tunnels. One module wide and bus powered, it is the device that lets a multi-line KNX project use IP as its backbone and still give Home Assistant a way in.
