Testimonials
"At DEW21, our goal is to enable our customers to manage their energy simply and centrally in one place — without having to deal with multiple isolated solutions. With our HEMS in the DEW21 EnergyControl app, they can monitor and control their PV system, wallbox, smart meter, or heat pump in one app and plan their consumption more efficiently."

Head of Sales & Operations, DEW21
"For a long time, our swimming pools lacked transparency about the main drivers of our energy costs. With Zählerfreunde, we now have this transparency. The load profile analysis is also highly valuable. By identifying peak loads early and making targeted adjustments to our processes, such as optimizing sauna operating times, we were able to achieve noticeable savings.
