What eBZ does

eBZ GmbH is a privately held German manufacturer of electronic electricity meters, founded in 2014 and headquartered in Bielefeld, North Rhine-Westphalia. The company designs, develops, and produces modern measurement devices (moderne Messeinrichtungen / mME) that comply with the German Messstellenbetriebsgesetz (MsbG), targeting municipal utilities, network operators (Netzbetreiber), and metering operators (Messstellenbetreiber). Its flagship product is the DD3 base meter, a compact device with temperature-stable shunt measurement, resin-cast single-board design, manipulation protection, 730 days of historical data storage, and 64 hardware/software variants; from this platform eBZ has derived four wireless variants (MD3 with MeDa@home, WD3 with wireless M-Bus, RD3 with LoRaWAN, and YD3 with mioty) plus two iMsys upgrade adapters (BAB-wMB-E01 and BAB-RS485), enabling operators to deploy the same physical base across multiple connectivity strategies.

The business is a single-site, vertically integrated B2B hardware operation. Production runs on a fully automated line capable of up to 3,000 meters per day and 700,000–800,000 meters annually on three shifts with only three operators, reaching the 3.5 millionth cumulative unit milestone in 2025 from over 250 customers since 2016. Revenue is generated exclusively through direct enterprise sales to German operators, supported by a regional field sales structure (North and South Germany), inside sales, recurring 'Quality Days' transparency events (32 editions engaging 210+ contacts from 90+ operators), and presence at sector trade shows such as E-world, DEUMESS, and Stadtwerke Tagung. The company holds ISO 9001, ISO 14001, ISO 45001, and MID certifications, develops in-house accelerated lifetime testing (24-year design life target, 500 thermal-shock cycles, >1,000 hours at full load per DIN EN 62059-32), and holds seats on OMS Working Groups AG1 and AG3.

Geographically the entire footprint is domestic (Germany), with no documented international sales or channel structure. Recent strategic activity through 2024–2025 has been product-focused (YD3 mioty launch, DD3-K cage screw terminal variant, DIN rail housing prototype), partnership-driven (VALENDA Metering for wireless MSB rollout models, smartOPTIMO for events, eweco for plug clamp installation accessories), and organizationally marked by the January 2025 leadership transition from Dr. Uwe Schöneberg to Michael Schwetje as Managing Director and Technical Director.

It features two optical interoperable data interfaces (MSB and INFO), temperature-stable shunt measurement, a compact single-board design with resin casting, manipulation protection and upgradable to BSI-iMsys via adapter modules. The base product is sold to German network operators and metering operators.
• MD3 with MeDa@home Radio Module The MD3 is the DD3 base platform extended with an integrated MeDa@home radio module per innogy specification, providing wireless communication for German smart-metering operators. It includes a bidirectional MSB data interface (1s Push & Pull, SML 1.05) and received MID approval in 2018.
• WD3 with Wireless M-Bus The WD3 extends the DD3 platform with an integrated wireless M-Bus radio module (OMS 4.1.2), enabling wireless connection to BSI-certified Smart Meter Gateways (SMGW). Variable transmission power is configurable via the bidirectional MSB interface, and the meter is approved under MID and PTB A20.1/A50.8 since 2019.
• RD3 with LoRaWAN The RD3 adds integrated LoRaWAN connectivity to the DD3 platform per LoRa Alliance specifications, supporting long-range, low-power wireless communication. Features include Mode C (bidirectional), ST Chip, Class C and OTAA activation, with configurable transmit interval and payload contents over-the-air, approved under MID since 2020.
• YD3 with mioty The YD3 provides integrated mioty radio connectivity for the DD3 platform per mioty alliance specifications, operating in the ISM band 863-870 MHz in EU0 or EU1 mode at 14 dbm / 25 mW transmit power. Each unit ships with a preconfigured EUI, mioty network key and mBus key, MID-approved since 2024.
• DD3-K with Cage Screw Terminals DD3-K is a variant of the DD3 modern metering device introducing new cage screw terminals (Käfigschraubklemme) in both round and square configurations. It retains the DD3 measurement and interface features while adding a more installer-friendly connection technology, brought to market in 2025.

Closely comparable to eBZ because EMH produces certified mME devices for the same German market, competes on similar value drivers (quality, certification, wireless modules), and serves overlapping utility customers.

Emerging players

• PPC (Power Plus Communications): German supplier of BSI-certified Smart Meter Gateways (SMGW) and broadband powerline communications for smart metering. Adjacent peer to eBZ because PPC provides the gateway layer that pairs with eBZ's mME base meters to form a complete iMsys per BSI-TR03109.
• Theben (Theben AG): German manufacturer of KNX building automation, smart home and energy management products. Emerging/adjacent peer to eBZ because Theben operates in the consumer-side smart home and submetering space where eBZ meters integrate via optical INFO interface or wireless M-Bus.

Broad incumbents

• Itron: Global smart infrastructure and metering company with a strong portfolio of electricity, gas and water meters. Comparable to eBZ on electronic meter technology and utility customer base, though much larger and more geographically diversified.
• Kamstrup: Danish manufacturer of smart metering solutions for electricity, heat, water and gas with strong European presence. Comparable to eBZ on electronic electricity meter manufacturing and wireless communication, but with broader portfolio and international footprint.
• Landis+Gyr: Global leader in smart metering with a broad portfolio of electricity, gas, heat and water meters. Directly comparable to eBZ because Landis+Gyr serves the same German network operators with certified electronic meters (including mME / iMsys), but at vastly greater scale and across many geographies.
