New IoT-innovation uses LoRaWAN® and puts a stop to wild waste of water – in toilets



A running toilet can waste up to 1,100 liters – or 10 bathtubs – of clean water in just 24 hours. Brunata’s newly patented Smart Building Running Toilet service uses IoT and LoRaWAN® technology to help tenants and administrators save on a resource that is becoming scarce all over the world as climate is changing.

Climate change is reshaping Europe’s freshwater resources. Scarcity looms in dry regions and urbanized areas, and we need to find new ways of protecting this precious and vital resource.

All over Europe, leaking toilets are a common source of waste, but often go unnoticed. At 8 liters/hour, it can be almost invisible, while a full one can waste more than 150 liters every hour. Estimates are that 5-8% of all toilets have a present leak.

A team of Brunata’s technicians has now developed a simple, yet ingenious IoT solution for this problem: the “Running Toilets” service.

This new Smart Building service uses intelligent vibration sensors synced with Brunata’s LoRaWAN® network for efficient data collection. When a sensor detects constant water flow to a cistern, the system warns tenants and administrators, urging them to take action and literally stop money from running down the toilet. In other words, Running Toilets help people save money and protect the environment.

Brunata’s already proven and extensive LoRaWAN® network is developed for remote reading of consumption meters like water meters and energy meters. This makes it the perfect match for Smart Building solutions like the new “Running Toilet” service.
The benefits of Brunata’s LoRaWAN® network are that it is ideal for collecting and processing data from meters, sensors, and similar technological devices. The LoRaWAN® network is easy to install and can cover large areas in dense buildings.

Brunata Smart Building combines intelligent sensors, maintenance services, and an online platform that provides easily comprehensible insights into the condition of your residential properties, and the possibility of setting up alerts for alarms and e-mail notifications.

Minol ZENNER Connect goes Europe-wide


Minol ZENNER Connect goes Europe-wide – ZENNER IoT PLUG&PLAY solutions are now available in many European countries.

The Internet of Things (IoT for short) is an important driver of digitalisation for public utilities, energy providers, municipalities, industry and SMEs. ZENNER is one of the leading technology providers in this field. After many successful projects, the company is expanding to make its IoT PLUG&PLAY solutions available in many European countries in future.

As of now, the smart ZENNER IoT PLUG&PLAY solutions for use in Minol ZENNER Connect GmbH’s LoRaWAN® network are available not just in Germany but also Austria, Denmark, Sweden, Poland, France, the Netherlands, Spain, Italy, Croatia and Slovenia. Other countries will follow later this year.

LoRaWAN® allows customers to transmit their sensor data securely and reliably via the Internet of Things. The Minol-ZENNER Group offers its own network for this purpose. “We are now one of Europe’s largest LoRaWAN network operators, providing our customers with reliable network operation, monitoring the network for outages, coverage gaps and capacity, and also ensuring that each country’s respective regulatory requirements are met,” reports Marcus Kirchdörfer, Managing Director of Minol ZENNER Connect GmbH, the group’s LoRaWAN network operator. Today, MZC’s network already comprises more than 46,000 LoRaWAN gateways and around 4 million LoRaWAN terminals.

The fact that digital IoT solutions can be used professionally, not just for large-scale projects, but also on a smaller scale, is demonstrated by the ZENNER IoT PLUG&PLAY solution portfolio, which was specially developed for SMEs and smaller commercial enterprises. “We have observed for some time that many SMEs and commercial enterprises are very interested in using digital solutions selectively or combining them with each other. This includes, for example, for detecting leaks or monitoring roller doors, filling levels, storage and cold rooms.

During the coronavirus pandemic, there was also a surge in demand for solutions to monitor indoor air quality in offices, schools and public buildings, including measuring CO2 levels,” reports Boris Stöckermann, Head of New Business Europe at the Minol-ZENNER Group.

ZENNER IoT PLUG&PLAY focuses on processes that are as straightforward and user-friendly as possible. The ZENNER IoT-GatewayPLUS Smart is simply plugged into a socket and automatically connects to the Minol-ZENNER Group’s LoRaWAN® network via the customer’s WLAN. New sensors purchased via the online ZENNER shop can be optionally delivered pre-configured, connect automatically to the network during commissioning, and be mapped in the B.One Gallery visualisation platform. Individual use cases can be freely combined with each other. True to the motto Gateway Sensor, Ready, Go!

“The idea of being able to implement digitisation yourself even without extensive IT knowledge is well received in the market,” explains Stöckermann. “Our goal is to keep customer effort as low as possible. Putting devices into operation with ZENNER IoT PLUG&PLAY is no more complicated than integrating electrical devices into your home WiFi. However, if any questions arise, the B.One Community provides users with a specialist forum where laypersons and experts can constructively exchange experiences. For more extensive projects that require individual project management, interested parties can contact the ZENNER IoT project team via the shop.”

“Besides our own products, our portfolio currently includes over 200 smart IoT sensors and gateways from the most popular manufacturers, which can be used to achieve countless smart use cases – on both small and large scales. The spectrum of solutions ranges from the intelligent digitisation of individual tasks to the creation of complex digital ecosystems,” explains Stöckermann.

The installed sensors send the status data to the corresponding gateways via the Internet of Things. From there, the data is forwarded to an IoT platform where it is available for many applications. All data is encrypted before transmission. Corresponding solutions, e.g. for visualising devices and data, are available on the IoT platform.

ZENNER has been one of the pioneers for years and offers end-to-end complete IoT solutions from a single source, from measurement technology and sensors to telecommunications infrastructure and data services, right through to the finished application. Whether you’re after a classic smart city solutions such as demand-based street lighting control (smart lighting), intelligent parking solutions (smart parking) and demand-oriented waste disposal (smart waste) or solutions for intelligent buildings (smart buildings) – digitalisation offers countless opportunities to optimise processes, save costs or sustainably improve a carbon footprint. The company relies primarily on LoRaWAN® technology. “With the global radio standard LoRaWAN, data from thousands of devices and sensors can be transmitted over long distances quickly, securely and with minimal energy consumption,” says Stöckermann.

You can experience the smart IoT solutions live at the LoRaWAN World Expo, the world’s largest LoRaWAN exhibition, in Paris on 6 and 7 July. There, ZENNER and Minol ZENNER Connect will be exhibiting together with partners Brunata, SmartMakers and asvin, as well as presenting the ZENNERShop for IoT sensors and solutions.

New digital platform for administrators and brand-new mobile app for residents



Brunata Online is used by property administrators to get an overview of energy consumption and expenses in residential buildings. At the same time, the platform is an important source of information on, e.g., major deviations in energy consumption that may require rapid intervention to avoid unnecessarily high costs.

Now, the platform is also available in a version for building residents. With Brunata Online for Residents, each resident has the possibility to follow their own consumption of heat, water, electricity and gas day by day, and the consumption can be monitored more precisely for each meter in each room. Among other things, the resident can compare consumption with previous periods, and see if there are major deviations, which makes it much easier to adjust consumption and thus save on energy bills.

New mobile app makes it even easier

At the same time, a brand-new app for residents will be launched, making it even easier for individual residents to check their consumption. All available data is presented in a simple and clear way in the app. Residents can compare consumption to previous periods, set alarms for consumption fluctuations and receive energy saving tips.

The app can be downloaded from the App Store or Google Play (if the property has signed up to the service).

Good news for administrators too

There is good news for administrators as well. With the introduction of an updated version of Brunata Online, administrators will also find new ways of optimizing their work.

The new generation of the system has been redesigned with a simpler interface, making it even easier to get to the information you need. Data is quick to read, navigation is intuitive, intelligent features are added all the time. As a new feature, it will be possible to invite new users and residents by email.

All in all, both residents and administrators get a better overview, which can save time on administrative tasks and money on energy bills.

Innovative e-Mobility Solutions for Municipal Utilities



Zenner and GP Joule Connect bring new e-mobility solutions for municipal utilities and energy providers into the market. Already integrated is the transmission of data via a smart meter gateway, which is partly required from 2021.

In order to integrate holistic e-mobility solutions into modern district and smart city concepts, Zenner and GP Joule Connect have developed a package that combines CLS (Controlled Local Systems) and LoRaWAN® technology with mobility solutions. (copyright: GP Joule)
Municipal utilities (known as Stadtwerke) also want to position themselves as service providers for cities, districts or regional companies in the domain of electromobility. Sebastian Heß, Managing Director of Zenner Hessware GmbH: “The entry into electromobility has several advantages: In addition to income from electricity sales, for example, the smart operation of the charging infrastructure guarantees secure network control through the monitoring and control of charging points.” An important aspect, as it is becoming more and more important to monitor load conditions and to switch charging stations intelligently. With CLS management from Zenner Hessware, this is now possible under regulatory compliance.
In order to integrate holistic e-mobility solutions into modern district and smart city concepts, Zenner and GP Joule Connect have developed a package that combines the CLS and LoRaWAN® technology with mobility solutions. An example of this is data transmission via a smart meter gateway.

Smart meter gateway as a secure communication channel

Starting in 2021, it will be mandatory for charging stations with consumption of over 6,000 kWh to use Smart Meter Gateways (SMGW). Charging points must then be controlled in accordance with the requirements of the Federal Office for Information Security (BSI).

However, the advantages of Section 14a of the Energy Industry Act (EnWG) can also be exploited in this way. This promises the operators of controllable consumer devices a reduced network fee. The prerequisite for this is the role as an active EMT at Zenner Hessware. This provides an integrated solution for the control of charging infrastructure including data transmission via SMGW.

E-mobility as a smart city solution

In addition, Zenner has developed a LoRaWAN®-supported smart parking solution that shows the actual occupancy of the parking area in front of a charging station. It is true that operators of charging stations can usually determine whether an electric vehicle is being charged. However, it remains unclear whether a supposedly available e-parking space might actually be occupied by a non e-mobility vehicle.

By combining data about the operating status of the charging station and the availability of the parking space on a single platform, real-time reliable information about free and functional parking spaces for electric vehicles can be made available via a smart app.
