# TapHome to KNX

Learn how to expose TapHome IO modules on the proprietary bus and make them accessible within ETS through KNX Gateway integration.

Last updated: 2025-11-21

Expose devices feature lets you use TapHome IO modules on its proprietary bus and make them visible / available inside ETS.

## 1. KNX Gateway

In Hardware → TapHome Bus scan for the KNX Gateway device.

## 2. Add KNX interface to Expose Devices

In Setting choose Expose devices and click Add new interface:

## 3. Add devices to KNX Expose Devices Interface

When the KNX interface is defined you can click on Add device:

Choose from list of device and click Next:

Select the new exposed device and fill the parameters defined in ETS for exchanging data between TapHome bus and KNX bus:

DTPIndex is the data point number, DTPType is the data point type. CommandType defines the TapHome device action which has to be exposed to KNX bus.
