ViCare Achieves One Million Users: Powering the Energy Transition Through Connected Homes
The Viessmann Climate Solutions app ViCare is celebrating a milestone: as of today, it counts more than 1,000,000 registered users. ViCare allows users to conveniently manage their climate system remotely via smartphone or tablet and actively save energy (costs).
Allendorf (Eder), Germany, June 5, 2025 – The Viessmann ViCare App announce a significant milestone: it has now reached one million users. With ViCare, users can manage their climate system remotely via smartphone or tablet to save energy(-costs). This platform is offered by Viessmann Climate Solutions (VCS), which is a part of Carrier Global Corporation (NYSE: CARR), global leader in intelligent climate and energy solutions.
Enabling end user to sustainable energy consumption
ViCare is more than just an app – it's an active partner for more sustainable energy consumption. Almost 80 % of users actively engage with the app regularly, making it a central tool for optimizing energy usage in residential buildings. Notably, each ViCare-managed home contributes to significant savings in heating-related CO2 emissions and energy efficiency improvements.
ViCare Today: A Successful Team and a Strong Platform
Today, ViCare is hardly recognizable from its early basic version. The average rating of 4.6 stars in app stores is the well-deserved reward for years of hard work, continuous improvement, and countless iterations. The platform now seamlessly integrates ten different technologies – from heat pumps and gas condensing boilers to solar systems and battery storage. What was once a niche app has become a comprehensive control center for the modern home, trusted by over one million households worldwide. This success is the result of cross-location collaboration between teams in Allendorf, Berlin, and Wrocław (Poland).
The team behind ViCare has grown with the platform. The small group of pioneers has become a large, dedicated team of experts who continue to be driven by a passion for technology and the desire to make a real difference for users. It was never just about developing technology, but about giving people control over their energy consumption and supporting them on their path to a more sustainable life.
The Journey to One Million: A Story of Pioneering Spirit and Teamwork
In the early 2010s, the concept of smart, connected heating was still largely a thing of the future. ViCare's journey began with Vitotrol, a basic app for remote heating management that utilized an external cloud.
A significant shift occurred in 2015 with the creation of the internal "Backend/Frontend-Teams." Their crucial task was modernizing an existing system with thousands of users. At the same time, many tests with end users were on the agenda to ensure a smooth transition.
January 2018 marked the start of development for the fourth and most recent cloud generation, introducing the new Viessmann API. The data model was collaboratively designed by ViCare developers and the device communication team, resulting in a more flexible, feature-based structure. This approach proved highly successful and remains the stable foundation of ViCare today.
