The digitalization of analog and manual meter reading processes opens up additional savings potential in general metering and increases customer convenience. In order to be able to fulfill the supply mandate economically in the future, municipal utilities are relying on the digitization of their infrastructure with the help of smart metering and control devices connected by an IoT network. If the right decisions are made when selecting this network, the newly built network can not only reduce costs but also generate revenue in the long term.
IoT products in this industry are generally subject to the requirements of country-specific data protection as well as the regulatory requirements of the BSI and the relevant industry-specific regulations "EU Security Assurance Levels High" for critical infrastructures. Our solution for smart metering combines the cost-effectiveness of LoRaWAN®-based remote meter reading with the high security standard for WAN security required by the BSI in accordance with BSI-TR-03116-3, enabling our customers to use LoRaWAN® as a secure alternative to the smart meter gateway in a wide range of applications.
An alternative LPWAN transmission technology can be used for meters without mandatory smart meter gateways, such as all water meters. Here, the commercially available LoRaWAN® radio technology does not meet the BSI's high security requirements for WAN security due to the lack of TLS encryption preferred by the BSI. In addition to data security, data protection is also an essential factor for the acceptance of remote meter reading and the consent to further services. With the SIoT product, PHYSEC enables complete fulfillment of all data protection and security-relevant specifications, according to the current state of the art.
Similar to the remote reading of the water meters, there is also no obligation for heat meters to be connected to the smart meter gateway. The requirements for mandatory remote reading are defined in the FFVAV, whereby the state of the art in terms of security must be implemented. Likewise, data protection issues must already be taken into account during the connectivity integration due to the personal reference of the data. PHYSEC's SIoT module addresses these issues holistically for the sustainable digitalization of heating networks. For heat network optimization, PHYSEC has also developed an application that enables amortization of the investment in remotely readable heat meters after a short time.
With the national implementation of the EU's Energy Efficiency Directive (EED) in the form of the amendment to the Heating Cost Ordinance, new technical challenges are coming into focus. In analogy to the reading of heat meters, the consideration of the state of the art in security and the possibility of connectivity to an SMGW is particularly relevant.
Heat cost allocators and other units are very attractive products for IoT applications, as high volumes combined with high accessibility and fully automated processes are in demand from utility companies.
