FAQs
What is a smart meter gateway, and what does it do?
A smart meter gateway (SMGW) is the interface between the digital electricity meter in your home or your own energy generation system (if you have one) and the public power grid.
Devices connected to the smart meter gateway can send and receive data securely and without interference. All communication is encrypted.
What is a smart metering system (iMSys)?
A smart metering system consists of a smart meter (digital metering device) combined with a smart meter gateway (communication unit) and replaces analog Ferraris electricity meters. Together, these two devices can measure the current meter reading as well as electricity consumption at the actual time of use (e.g., per day, week, month, or year).

Why do we need smart metering systems?
The increasingly decentralized feed-in of renewable energy—such as from residential solar systems—poses a major challenge for energy supply systems. On the one hand, energy from renewable sources is fed into the grid at unpredictable times; on the other hand, energy consumption at certain times of the day can create significant peak loads. As part of the rollout of smart grids, smart metering systems are being implemented in accordance with the “Act on Metering Point Operation and Data Communication in Smart Grids” (MsbG, see https://www.gesetze-im-internet.de/messbg/).
The smart metering system will be a central component. Data protection is particularly important in this context. The energy supply and your data must be secure. The legislature therefore mandates high security requirements, which the Federal Office for Information Security (BSI) monitors.
To this end, the Bundestag passed the Act on the Digitalization of the Energy Transition (GDEW) (PDF, 264 KB). This law aims to establish a modern infrastructure for the energy transition. This affects everyone, as a new technology is being rolled out.
By using these legally mandated metering systems, which are integrated into a communications network, you as a consumer will gain greater transparency into your own energy consumption and the ability to analyze your consumption patterns in order to reduce your energy costs based on your current usage. With the help of modern rate plans—which are reflected and made possible by the metering system—you can manage your energy consumption intelligently.
What benefits do I get from a smart metering system?
Smart metering systems are a versatile solution for reducing energy costs and increasing efficiency and comfort.
- Transparency and Energy Savings
With smart metering systems, you can track your electricity usage much more accurately and transparently than ever before. Thanks to new technical capabilities, you can also track historical electricity usage—such as daily readings—and more easily understand your consumption patterns and electricity bill. And when you have a better understanding of your consumption patterns, it’s easier to save electricity. - More Accurate and Convenient Billing
Your consumption data is automatically transmitted to your meter operator on a regular basis—eliminating the need for manual meter readings in the future. Your electricity provider can also offer you the option of monthly direct billing; you’ll pay only for the electricity you’ve actually used, eliminating inaccurate estimated payments or additional charges. - One device for electricity, gas, water, and heat
The smart meter gateways are designed to also process your gas, water, or heat consumption. If your meter operator offers this service, you can measure all your consumption and analyze it at a glance—for example, via an app. This is convenient and saves money. - Ensuring a Successful Energy Transition
Smart metering systems are needed to integrate more electricity from renewable energy sources into the power grids. The wind doesn’t always blow, and the sun doesn’t always shine. Yet electricity must flow steadily at all times. Transportation, too, is increasingly being converted to renewable energy. When many electric cars charge at the same time after work, the grids reach their limits. Smart metering systems make it possible to coordinate generation and consumption. They enable grid operators to utilize their power grids more efficiently. This is cheaper and faster than laying new power lines. In this way, we avoid construction sites and higher grid fees for electricity customers.
Are data protection and data security guaranteed?
The legislature has established strict requirements for data protection and data security. The Federal Office for Information Security (BSI) develops so-called BSI protection profiles and technical guidelines for this purpose and is constantly refining these requirements.
Based on these binding standards, smart meter gateways are tested and certified by the BSI and are thus intended to ensure a consistently high level of protection. The installation requirement does not take effect until the BSI has certified the devices. The security standards implemented in smart meters are even higher than those used in online banking, making the data extremely secure. With this standard, Germany is a pioneer in Europe.
The law also specifies exactly who is permitted to receive which data. The smart metering system transmits the data in anonymized form—and, where applicable, even in pseudonymized form—and only to authorized recipients. Data may only be used for clearly defined purposes. This is expressly stipulated in the Act on the Digitalization of the Energy Transition. Once the transmitted data has been processed for its specific purpose, it is deleted.
Is a smart meter gateway a smart meter?
The smart meter gateway is not a meter. It collects the meter’s readings, stores and processes them, and then transmits them in encrypted form to your meter operator. Throughout the entire process, your meter readings are protected against tampering and unauthorized access.
Why should I share my meter data with anyone?
Most importantly, so that your energy provider can accurately bill you for what you’ve used, or so that you can get paid for the energy you generate if you have renewable energy systems in your home.
You might want to track your own energy usage and see where you can save. If you have an alarm system, you may want to grant a home automation company permission to install a health monitoring system in your home.
If you have a battery or a charging station for an electric vehicle, you might want to share it if you have extra capacity that can be used by the power grid.
Who is required to have a smart metering system installed?
Under applicable laws, metering point operators are required to equip electricity customers with an annual consumption of more than 6,000 kWh with a smart metering system. For electricity consumption of less than 6,000 kWh per year, installation is optional, and the decision rests with the primary metering point operator.
Metering point operators have a total of eight years to retrofit the metering points subject to mandatory installation, following confirmation of technical feasibility, which has been in place since January 31, 2020. However, within this period, at least ten percent of these mandatory installations must be equipped with a smart metering system within the first three years.
The Metering Point Operations Act stipulates that by 2032 at the latest, every household must be equipped with a modern metering device or a smart metering system.
How much does installation cost, and who is responsible for it?
Your energy provider (metering point operator) is responsible for installing the SMGW.
As an end customer, can I access my consumption data?
The Smart Meter Gateway allows you to view your consumption data (in the form of register values and measurement lists), analysis profiles, and log messages that pertain to you. To do so, you can either use the Transparency and Display Software (TRuDI) or our browser application. Access via the browser application is described in our SMGW manual for end users. Access via TRuDI is described in the corresponding manual from the Physikalisch-Technische Bundesanstalt.

How do I get my login credentials?
Using your login credentials, you can log in to the SMGW’s HAN interface and retrieve your measurement data locally. Your login credentials will be issued by your MSB only after production. Since we no longer have access to the devices once they have been manufactured, please contact your MSB directly with any questions regarding your login credentials.
As the manufacturer, we provide general information about the Smart Meter Gateway—including our manual for end users—on our website.
Regarding options beyond the functions described in the manual—such as viewing your current electricity consumption—only your energy supplier can provide further information. The services offered to end users vary from supplier to supplier, and as the device manufacturer, PPC unfortunately has no influence over the scope of these services.

How can I change the IP address for local access to my meter readings?
When ordering our SMGWs , the metering point operator (MPO) select the IP address at the HAN interface. If they do not, a “default IP address” will be used. You can find this in our consumer manual. Once the devices have been manufactured, we no longer have access to them, and the IP address can only be adjusted by the MSB . We therefore ask that you direct any questions regarding the IP address of your SMGW contact your MIO .
