This is energy controlling

Goal - Optimise the energy efficiency of buildings, facilities, machines and processes; lower energy costs, protect the environment.

What - Analyse energy consumption, process data, environmental variables and performance indicators in order to identify and evaluate saving potentials.

Tool - Data analytics platform for all consumption data and relevant variables. In high resolution and real time.

Don't - Excel-based compilation and analysis of consumption data is highly inefficient, very error-prone and of rather limited value.

BETA tests are starting: Dashboards are now optimised for mobile use!

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?

Flexibly connect LoRaWAN sensors via The Things Network or the IoT platform Element IoT

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.

deZem now supports MQTT protocol

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.

If you are interested, please contact us!


HarvyLR: New self-powered, battery-free LoRaWAN sensor

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.

Taking advantage of synergies: Asseco Berit & deZem combine their solutions

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.

Interactive process visualisation - custom-made and up to the minute

The deZem sensor landscapes are interactive graphics on the deZem dashboards into which metering points from deZemVis can be integrated. In this way, metered values can be viewed live and for any point in time in the past. Limit violations can be detected immediately by means of colour changes.

Sensor landscapes are zoomable and can be used as versatile process visualisations. With one click you can jump to the individual time histories in deZemVis with more analysis tools. Sensor landscapes are suitable for CHPs (see example on the right) as well as for industrial processes, plants, office buildings and all kinds of process visualisation. We will be happy to create them according to your wishes within a few days.

Your interactive sensor landscape is only one click away!
