Danpower – Enercity - Telekom

Joint project by Danpower, enercity contracting and Deutsche Telekom

The amended Heating Costs Ordinance (HKVO) came into force on December 1, 2021. The German government has thus ensured that the requirements of the European Energy Efficiency Directive (EED 2012/27/EU) are transposed into national law. In accordance with "Article 9c of the Energy Efficiency Directive", the updated HKVO stipulates, among other things, that all newly installed meters and heat cost allocators must be remotely readable from 25.10.2021 and that devices already installed must be retrofitted or replaced by 01.01.2027.

Against this legal background, the project "Remote readability of heat meters" was initiated as a joint project by Danpower, enercity contracting and Deutsche Telekom, which has now gone live.

The aim of the project was to map a secure, manufacturer-independent and automated remote reading of heat meters via NB IoT Gateway on Deutsche Telekom's Cloud of Things in order to be able to continuously digitize the downstream billing processes due to the current legal requirements (EED, UVI).

WEPTECH, as a project partner of Deutsche Telekom, has realized the connection of the SWAN2 gateway based on the LwM2M protocol for this future-oriented solution, which enables meter data to be received on the Cloud of Things (CoT), decoded (parsed) and thus made available for billing systems of energy service providers. We have also registered LwM2M smart meter objects with the OMA (Open Mobile Alliance). This means that these data can be recognized and processed directly as meter data on platforms, says Wolfgang Esch - Head of Sales & Marketing - at WEPTECH.


RWW "Wasserheld" relies on the SWAN
Leak detection and monitoring of water consumption

RWW "Wasserheld" relies on the SWAN

RWW Rheinisch-Westfälische Wasserwerksgesellschaft mbH - part of Westenergie - was recognized as a TOP local supplier in the water segment for quality, transparency and sustainability by the "Energieverbraucherportal" in 2023. This quality seal documents the conscious use of water as a resource and is awarded to local suppliers that are particularly consumer-friendly, service-oriented and innovative.

RWW's "Wasserheld" is also service-oriented and innovative, a project that has now gone "live" with a roll-out. The aim of the project is to provide private and industrial customers with information on water consumption via an APP application and to detect possible leaks via an alarm. Of course, this is also linked to the aim of motivating consumers to use the valuable resource drinking water consciously and sustainably.

A functioning water supply is an essential part of the infrastructure of any community or town. An efficient and reliable water supply is necessary to meet the daily demand for drinking water and at the same time ensure that the supply system works effectively and water losses are minimized. According to statistics, a water pipe bursts in Germany approximately every 30 seconds as a result of ageing, frost damage, etc. Tap water damage often goes unnoticed for a long time.

The consequences are time-consuming and costly repairs, but also the loss of precious drinking water. The "Wasserheld" was created to detect leaks at an early stage and minimize the damage. This cloud solution works very simply. Customers can monitor their water consumption via an app or web interface. If there are significant deviations in consumption, the app generates an automatic warning message.

For this to work technically, the data of the respective water meter must be transferred to the RWW Cloud, i.e. the water meters must first be "upgraded" to remote readability. This can be done quickly and easily by customers themselves without any great effort. All they need to do is attach a radio adapter to the water meter, which sends the meter values to the SWAN gateway from WEPTECH using the standardized wM-Bus protocol (EN 13757-4). The SWAN is a powerful, battery-operated gateway that transmits the received meter data securely at defined intervals via LTE Cat. NB1 (Narrow Band IOT) to the RWW cloud platform at defined intervals. Using the "Wasserheld" APP (or via the web interface), customers can monitor their consumption on a daily basis. Thanks to the remote readout capability, time-consuming manual meter readings by the supplier can be dispensed with in future. In addition, a corresponding alarm message is automatically generated if values deviate significantly, indicating a possible leak. All in all, the "Wasserheld" offers a valuable benefit to everyone involved and thus represents an innovative solution for the sustainable use of drinking water as a resource, according to project manager Michael Fech from RWW.
