More quality with less effort for residents.

We are an international company headquartered in Germany and is one of the leading providers of consumption data recording and billing for energy in buildings. Our goal is to make energy transparent by optimizing and digitizing buildings in over 20 countries to make them future-proof.

We make buildings sustainably valuable. To do this, we manage data and processes that make properties climate-friendly, safe and comfortable. We already have over 43 million connected devices in use worldwide and are developing solutions for the intelligent and energy-​​efficient buildings of tomorrow.

Our data-​based products and services make individual energy consumption transparent to residents so they can save energy, costs and CO₂.This in turn makes it easier to increase the energy efficiency and thus the value of the property. As a driver of innovation, we are consistently gearing our infrastructure towards the Internet of Things.

We rely on the latest and proven technological standards - both wireless and wired - to ensure precise measurement results and create valuable services for customers. We use and develop technologies that really prove themselves in daily use. They are state of the art and work reliably to transmit data securely. 

We can look back on over 50 years of company history and combine this long-standing experience with modern expertise to offer forward-looking solutions in building management.
