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 – no personal data is collected, other than the IP address.

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.
