Controlling Two Lights with a Single Button

This use case demonstrates how to control two different lights using a single push button by applying short and long press functionality.

Configuration of the Push Button

Open IHC Plugin > DEVICE MAPPING > Input Devices.
Select the input device you want to configure.
Set:
- Device type: Push button
- Function: Short / Long press
Assign KNX group objects for:
- Short press status
- Long press start status
  
  Existing group objects can be selected, or new ones can be created using the Add new object option.
Set the following functions:
- Short press function: TOGGLE
- Long press start function: TOGGLE
Save the configuration.

Functional Overview

The functional overview is illustrated in the diagram below.

A short press of the push button toggles the first light.
A long press of the same push button toggles the second light.

Each press type generates a separate status signal, which is mapped to individual KNX group objects and controls a different output device. This allows two independent lights or switches to be controlled using a single physical button.
