What QUNDIS GmbH does

QUNDIS GmbH is a German manufacturer of electronic submetering devices and system solutions for consumption-based billing of heat and water in residential buildings, founded in 1993 and headquartered in Erfurt. The company's product portfolio spans electronic heat cost allocators (Q caloric 5.5), ultrasonic and impeller-based heat meters (Q heat 5.5 US / R), electronic and mechanical water meters (Q water 5.5 / 4 / domestic), OMS-standard radio modules and gateways (Q module 5.5, Q gateway 5 / 6, Q node 5.5, Q repeater 6), smoke alarms (Ei650i, Ei6500-OMS), and supporting software tools. Its devices use patented ultrasonic transit-time measurement technology with a 1:100 dynamic range and communicate via the Open Metering System (OMS) radio specification, enabling interoperability across European smart-building ecosystems. QUNDIS complements the hardware with the Q SMP cloud platform, Q AMR automatic meter reading solution, Q walk-by mobile reading solution, and Q app / Q tool software for field digitisation, with products installed in more than 8 million residential units across over 30 countries.

QUNDIS serves a B2B customer base consisting primarily of metering service companies, property managers, and landlords across Germany, France, Italy, Spain, Turkey, and Slovenia, supported by regional sales offices in Paris, Milan, Istanbul, Madrid, Mannheim, and Maribor (WECONIS). The company sells hardware outright and generates recurring revenue from software/SaaS (Q SMP, Q app) and professional services (technical training for metering devices and system training for Q walk-by, Q AMR, and network technology); pricing is not publicly disclosed and is handled through direct sales and a login-protected B2B portal. The business is positioned to benefit from the EU Energy Efficiency Directive (EED), the German Heating Costs Ordinance (HeizkostenVO), and MID certification (Directive 2014/32/EU), with additional credibility from ISO 9001, ISO 14001, and eight consecutive years of EMAS environmental certification. QUNDIS GmbH is a wholly owned subsidiary of the noventic group and is led by Managing Director Volker Eck alongside Lars Bo Kristensen, Dr. Martin Kraus, and Head of Marketing & Communications Claudia Fiedler.

Core offering

QUNDIS manufactures electronic metering devices and end-to-end submetering system solutions for consumption-based billing of heat and water in residential and commercial buildings. The portfolio spans electronic heat cost allocators, ultrasonic and impeller-based heat meters, electronic and mechanical water meters, radio modules, gateways, network nodes, smoke alarms, and supporting software platforms (Q SMP, Q AMR, Q walk-by, Q app & Q tool) used by metering service companies and property managers. Devices communicate via OMS (Open Metering System) radio specification and are produced at the company's Erfurt, Germany headquarters, serving more than 8 million residential units in over 30 countries.

Product overview

QUNDIS offers a modular metering device ecosystem for consumption-based billing of heat and water in residential buildings. The portfolio centers on electronic metering devices (heat cost allocators, heat meters, water meters) that communicate wirelessly via OMS radio specification. The system architecture includes network infrastructure (Q node 5.5, Q gateway 5/6, Q repeater 6) for data collection, combined with software platforms (Q SMP, Q AMR, Q walk-by) for data management. Add-on modules (Q module 5.5, Q pulse R, Q M-Bus) enable retrofit of existing meters into wireless networks. Heat meters use either ultrasonic (Q heat 5.5 US) or impeller (Q heat 5.5 R) technology, while water meters come in electronic (Q water 5.5) and mechanical (Q water 4, Q water domestic) variants. Smoke alarms (Ei650i, Ei6500-OMS) complete the smart building offering. Products are manufactured in Erfurt, Germany, serving over 8 million residential units across 30+ countries.
