# Configuring KNX in ETS

Configuration guide for TapHome KNX Gateway using Weinzierl BAOS component in ETS software.

Last updated: 2025-11-21

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 this page](https://www.weinzierl.de/index.php/en/all-knx/knx-module-en/knx-baos-module-830-en).

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:
