Wohnio Tech Stack

IoT-based heating optimization for multi-storey residential buildings

Technology, Information and Internet Wien, Wien 11–50 employees Founded 2023 Privately Held

Wohnio builds hardware and software to retrofit existing heating systems in apartment buildings with IoT sensors and AI-driven optimization. The stack—Modbus, embedded Linux, ARM, Python, C++, plus industrial controllers from Siemens, Honeywell, and Schneider Electric—reflects deep hardware integration work. The project list shows heavy focus on legacy system integration and control-cabinet assembly, and the engineering-only hiring (4 senior, 2 mid-level roles) signals a technically demanding implementation phase rather than product-led scaling.
