What Brunata ZENNER srl does

Brunata ZENNER srl is the Italian operating entity of the Danish-founded Brunata group, which is itself part of the German-owned Brunata-Minol-ZENNER Group (15+ European entities, 4,200+ employees worldwide). The company delivers IoT-based metering and consumption-management solutions for water, heat, electricity, and gas in multi-unit residential buildings, housing associations, commercial properties, and water and district-heating utilities. The Italian entity operates with 11-50 employees out of Argelato (Emilia-Romagna) and is plugged into the group's pan-European distribution and LoRaWAN infrastructure.

The core technical stack centers on the B.One digital platform, which aggregates smart meters (ultrasonic and mechanical water meters, thermal energy meters, heat cost allocators), communication modules (NDC, EDC, PDC), LoRaWAN and Wireless M-Bus gateways, and Smart Building sensors (indoor climate, leakage, running-toilet, flood monitoring). Devices connect via LoRaWAN or Wireless M-Bus (OMS) to Brunata Online, a tiered subscription platform (Basic, Plus, Premium) with a consumer-facing MyBrunata app, enabling remote metering, consumption reports, alerts, and consumption-based cost allocation compliant with the EU Energy Efficiency Directive.

Brunata ZENNER srl generates revenue through a mix of hardware sales (precision meters and gateways, leveraging ZENNER manufacturing), recurring subscription fees (Brunata Online tiers, per-sensor Smart Building services), multi-year enterprise contracts with utilities and housing associations (e.g., the 10-year Lyse Energiservice AS partnership model), and professional services for installation, maintenance, and digitalization projects (e.g., water-utility digitization). Distribution combines direct enterprise field sales, the Brunata Online self-serve platform, the ZENNER partnership network spanning 100+ countries, and ZENNER's IoT PLUG&PLAY online shop for SMB and consumer channels.
