Contact interface, flush-mounted – 6-channel

Make your already installed pushbutton or switch smart, and control Homematic IP actuators and functions of your choice. To do that, install the IP contact interface - 6-channel.

Make up to six switches and pushbuttons smart at a later date.

You've created your home with a lot of passion and attention to detail - right down to the pushbuttons and switches that you've chosen. It would be nice to make the shutters smart with Homematic IP actuators at a later date. But what about the switches and pushbuttons? What would still look good? Yes! The contact interface lets you make your favourite switches and pushbuttons smart without changing their design.


The intelligent way to switch lighting

Integrate up to six pushbuttons or switches into your smart home system with the contact interface.


Control all possible functions in the smart home with your existing pushbuttons and switches.

Invisible installation

The very flat design enables you to mount the unit easily so that it's not visible from the outside.


The contact interface is fitted directly behind the installed switch insert in standard flush-mounted boxes.

Homematic IP: Smart living. Simply exciting.

Homematic IP means modern, flexible and secure technology from the European market leader*. Let the advantages of our system win you over, and start living smarter straight away. 

With some smart home providers, you have to make a choice: Do you have everything wired, or do you go fully wireless? Some systems are also hermetically sealed and do not accept devices from other manufacturers. Here at Homematic IP, we have a different approach. We are guided by you!

The Homematic IP app

Configure all the settings for your smart home in the Homematic IP app, and use it to control, regulate and monitor your devices whenever you want – without providing any personal data!
A smart home system is particularly robust, interference-proof and reliable when the devices communicate with each other via wired connections. And data transmission is very fast with cables, too. That all comes together with Homematic IP Wired.
