deZem News

As you know, deZem devised its product portfolio for doing energy controlling. Over the years, we have developed a system of software, hardware and services that our customers, however, use for many different purposes! They collect high-resolution time series from wildly diverse sources, facilities, processes, buildings. They do not just collect energy data – they collect IoT data!

Our customer’s objective is improving their energy efficiency, but often it is also more generally monitoring processes, reducing costs, increasing productivity, and optimising operations - in factories, data centres, hospitals, agriculture, administrative building, you name it. In short, the applications for deZem products have become as diverse as our customers!

At the same time, we have steadily evolved our product portfolio to embrace the rapidly growing Internet of Things (IoT) and related innovative technologies. Do you already know about our LoRaWAN und Edge Computing products?

Our website, on the other hand, so far continued to focus on the topic of energy controlling. Today, however, we have put online a revised landing page that reflects our broader focus.

It will take some time to update all our web pages and present all the different aspects of our IoT portfolio. Please continue to check for updates in the coming weeks. Quite possibly, you will find new ideas and solutions for your IoT project.

A final word: Energy controlling is a matter close to our hearts; of course we continue to optimise all our products for this important use case. In our opinion, improving energy efficiency by taking a detailed “digitized” look on consumption is the most effective and economic way to achieve climate protection and independence from fossil fuels.

We are very much looking forward to your feedback

IoT data always at your fingertips

Millions of sensor readings from machines, facilities and buildings arrive in the deZem IoT software every day. Visualising such Big Data in a way that is both easy to understand and allows for further analysis is a challenging task – even more so on small screens. In its latest update, deZem has therefore updated the design of the dashboard module deZemBoard and the visualisation and analysis module deZemVis. More importantly, deZem optimised the usage on mobile devices such  that information is readily accessible  and even in-depth analysis tasks can be performed ad-hoc on mobile devices.

A consistent and central database is the basis for identifying savings potential, monitoring processes, increasing productivity and automating operating procedures. However, in order to interpret machine-, energy- and environmental data, processes and their interactions, all this needs to be presented in a simple and comprehensive manner. In fact, it is often useful to clarify questions about anomalous or interesting data directly on site – on the smartphone.

With the latest update, the deZem visualisation and analysis software can be operated conveniently on small screens such as smartphones or tablets: Current and historical data is displayed on dashboards in so-called widgets as curves, bars, sankey diagrams, and many more ways. Intuitive navigation supports deep-diving into every detail. Comparing different media and time periods, statistical analyses and tables are implemented in a visually catchy way. Interactive tips and tricks support users in their navigation.

Your smartphone as telescope and microscope for IoT data

Diagrams must show a lot of information – axes and labels, legends and much more. Therefore they are notoriously difficult to display on small screens, especially when it comes to interactive usage. With the new version of the deZem DataSuite, the inherent potential of smartphones is fully exploited to present all information clearly, and to intuitively explore more details by tapping, swiping, dragging, rotating, etc. Of course, the same dashboards can be used on the desktop, as before.

Comprehensive management of notifications, alarms and comments

The presentation of relevant information on the actual data has also been optimised for display on mobile devices. Icons show whether an alarm has been triggered, a colleague has commented on a measurement, or whether a sensor stopped delivering data.

Over the past months, our front-end developers, UX/UI designers and testers have worked hard and no expense nor effort was spared to make our software module deZemBoard a pleasure to use on smartphones as well. We took the chance to integrate many new functions, for example a concise management of notifications and alarms.

Even before the official release, we would like to give our customers and interested parties planning to introduce software for their energy or IoT data management the opportunity to test the mobile dashboards now in the beta version.

We hereby invite you to the Beta-Test!

Are you interested?

Then simply contact us by email or phone.

We have good news for customers who already run a LoRaWAN network or are planning to build one and are still thinking about how to integrate data from the LoRaWAN sensors into our deZem analytics platform.

With version v3.50.1 of the deZemAd software module, it is possible to create and configure LoRaWAN devices collected via the LoRaWAN server The Things Stack (TTS) or Zenner’s IoT platform 'Element IoT' directly in deZemAd.

This innovation should be particularly interesting for municipal utilities. It allows them to use the extensive analysis functions of our deZem analytics platform in addition to their existing system.

You don't have a LoRaWAN network yet, but are interested?

Then contact us. deZem offers a starter kit to discover the LoRaWAN world and helps with the implementation and installation.

We will gladly send you detailed instructions on how to integrate LoRaWAN devices in deZemAd on request.

Message Queuing Telemetry Transport, better known as MQTT, has become indispensable in the Internet of Things (IoT) and especially in the Industrial Internet of Things (IIoT). Due to its extreme simplicity, this protocol is ideal for machine-to-machine communication. This is because it reliably transmits data even with low bandwidth and limited networks.

deZem has picked up on this trend and also offers a productive MQTT server. In this way, devices and systems that send and receive their data via the MQTT protocol can now also be integrated into the deZem IoT Suite.

We would be happy to set up a test access to the server for you.

HarvyLR is a brand new LoRaWAN sensor designed by deZem to detect AC and DC currents. The intelligent event filter integrated in the sensor provides metering series (inrush currents etc.) accurate to the second at a defined maximum rate.
Unlike conventional IoT sensors it does not require any external power supply or any battery at all. That means: No need for complex installation by laying additional cables. Since there isn’t any need to change the battery either, it is completely maintenance-free.

It is used, for example, in factory halls, building complexes or outdoor areas. There, analogue signals of 4–20 mA of corresponding transducers can also be recorded. The sensor can also be used to easily measure RMS currents in AC power supplies (in distributions or directly at the plants). In the latter case, the HarvyLR is simply connected to the appropriate deZem clamp-on current transformer. This already has a suitable plug-in contact. To ensure that the values are immediately available online for further purposes, the HarvyLR sensor is ideally suited for integration on the deZem IoT platform. However, it is also compatible with other platforms.

Configuration and firmware updates can be conveniently performed via Bluetooth.

The IoT sensor HarvyLR is available in two variants:

• HarvyLR-36: for deZem clamp-on current transformers W15, W80/T80 and W150 (provided that in general the load is below 100 A and 4–20 mA DC input signals)
• HarvyLR-360: for deZem clamp-on current transformers W300/T300, W500/T500

For more information, see the HarvyLR Data sheet.

deZem and Asseco BERIT have joined forces as partners and will henceforth offer their software solutions for energy- and cost-efficient, data-driven asset management.

Asseco BERIT's software solutions are, among other things, an asset register with an integrated geo-information system (GIS), a central instrument for the management of plants and network elements. With Asseco's SAMO solution, assets can be evaluated taking into account master and transaction data – throughout the entire life cycle.

Asseco BERIT's solutions thus offer an ideal complement to deZem's IoT analytics platform. With the connection of buildings, production facilities or operating equipment to the IoT platform, data from the asset is transferred to the deZem IoT analytics platform with one click. This makes real-time data and historical evaluations optimally available. In addition to detailed analyses, dashboarding, alerting, anomaly detection and reporting are possible in a variety of forms.

Facts, figures and analyses on COVID-19 up to date with just one click: We import the worldwide COVID-19 case numbers and present them in a deZemBoard [linked]. From there you can perform many interesting analyses yourself. Just call us to get the access data.

For example, the following information can be read directly for Germany (as of 26.5.20):

• the "degree of contamination" is 0.22 % (Qatar is the highest at 1.66%)
• the death rate is 4.62% (compared to 6.52% worldwide)

(It is well known that when interpreting the figures one has to take into account the limitations of statistics - testing capacities vary from country to country and nowhere are they sufficient to obtain a reliable number of actual infections).

An informative example is also the time-delayed correlation of reported new infections, recovery and deaths in the scatter plot. Accordingly, for the USA  (status 26.05.2020)

• the average time between discovery of the infection and recovery is 24 days
• the average time between discovery and death 4 days
• the mortality rate, taking into account this 4-day delay, is 6,5%
