EnQS is an independent development, testing and consulting partner for connected energy management and IoT systems. We support manufacturers and solution providers from software development and device integration to interoperability and end-to-end testing. Our work combines software engineering with energy devices, communication technologies and intelligent metering systems. In the EnQS Testlab, we develop and validate software and complete system solutions hands-on with real devices in a manufacturer-independent environment.

Testing & Software Development
Software development and testing for energy management and IoT solutions — from device and protocol adapters to control algorithms, integration, interoperability and complete end-to-end testing with real hardware.

EnQS Testlab
A manufacturer-independent test environment with real PV and battery inverters, EV chargers, heat pumps, smart meters and grid infrastructure — enabling reproducible integration, interoperability and end-to-end testing under realistic conditions.

Interoperability & Intelligent Metering Systems
Integration and testing of EEBUS and intelligent metering systems — from HEMS and energy devices to SMGWs, control devices, CLS, aEMT and GWA systems, including end-to-end applications for § 14a EnWG and § 9 EEG.

Technical Consulting
Technical consulting for manufacturers and solution providers — from system architecture and component selection to communication interfaces, interoperability and regulatory requirements for connected energy systems.
