Sustainable Solutions for Transparent Energy Use
Sustainability and climate protection are setting new standards for energy use – especially in buildings. Germany’s building stock is to become climate-neutral by 2045. Digital metering and submetering are key elements in achieving this. ZENNER Smart Submetering is a legally compliant and future-proof solution for utilities, metering service providers, and self-billers. In addition to the ZENNER device portfolio, a variety of supplementary services are available, including consulting, field service management, and consumption data visualization.
With our complete solution package – from metering technology to data services – you can now build your own digital infrastructure for smart submetering!
Submetering via Smart Infrastructure
In ZENNER’s smart submetering, data is transmitted via LoRaWAN®. Wireless heat and water meters, heating cost allocators, and other sensors transmit data at short intervals via radio to an IoT gateway.
How to smart submetering with ZENNER

Wireless measurement technology and sensors
With ZENNER, you can utilise a comprehensive product portfolio of wireless measurement technology. With our meters, you can realise the implementation of remote reading of water meters, meters for thermal energy (heating and cooling), heat cost allocators and smoke detectors as well as other sensors in smart buildings
Communication networks
We offer you access to one of the largest LoRaWAN® networks in Europe. Around 10 million measuring devices and sensors are already transmitting data every day via more than 100,000 installed LoRaWAN® gateways. This allows you to utilise all the advantages that LoRaWAN® offers, such as long ranges and low energy consumption
Solutions
We provide you with all your data securely and reliably at all times via our ZENNER Datahub as a central data hub. The ZENNER Datahub also offers an uncomplicated connection to various portal or billing systems.
