Heidi Systems

Heidi Systems GmbH provides digital metering, energy data management and billing solutions for residential and commercial properties. The company equips buildings with remotely readable radio meters for heating, hot and cold water, alongside devices such as smoke detectors and fire extinguishers. Its services include meter installation, ongoing consumption recording, heating-cost and operating-cost statements, interim consumption information, energy certificates, and support for large projects.

Consumption data is transmitted digitally and presented through a dashboard, helping property owners and managers monitor usage and prepare bills without manual readings or routine on-site visits. Heidi Systems also offers document management, notifications, consultation, planning, installation, service and maintenance. The company works with regional specialist tradespeople and serves property managers, housing companies, private equity firms and individual property owners. Its website states that installations of radio technology are offered at no cost, subject to the applicable arrangements. With more than 15,000 devices reportedly installed and locations across Germany, as well as operations in Austria and Switzerland, Heidi Systems positions its technology as a practical way to improve transparency and simplify property energy management.
