TapHome KNX Gateway uses a KNX component from Weinzierl called BAOS. The gateway is in ETS listed under the Weinzierl name. BAOS is KNX certified.
1. Import Product Database
Download product database from page https://www.weinzierl.de/images/download/development/830/Weinzierl_83x_KNX_BAOS_Module_ETS4.zip
Open ETS 5 → Catalogs → import Weinzierl product database from downloaded archive.
2. Add BAOS module to your installation
Change to Topology view in ETS project:
From producer catalogue choose Weinzierl producer and find KNX BAOS 832 module. Insert module to appropriate area and line.
3. Configure BAOS Data Points
Select BAOS module and switch to it parameters. Choose first data point group 1-10, select data point 1 type.
The description text of the data point, which is only visible if you enabled a data point, is just a text field which is not downloaded into the KNX device. It stays in the ETS project just for information. It helps the commissioner to give a name to every data point.
