SGH-S Smart Meter Gateway
The SGH-S (Smart Grid Hub – Secure) is the link between consumers and producers and takes on tasks such as tariff setting, processing and provision of billing data.
The communications gateway SGH-S takes on official tasks such as tariffing, processing and provision of billing data in strict compliance with data protection regulations. As a multifunctional device, the SGH-S connects the connection points of consumers, producers and prosumers with the applications and services of active and passive market participants in the network. The SGH-S thus plays a crucial role in the increasingly complex management of low-voltage and medium-voltage distribution networks in a decentralized and volatile energy supply. Of course, the necessary certifications for use in accordance with calibration law and for IT security are available from the Physikalisch-Technische Bundesanstalt (PTB) and the Federal Office for Information Security (BSI).

Highlights
The SGH-S from EFR offers numerous advantages beyond the basic functionality:
- Reduction in complexity: Upon request, EFR offers complete iMSys consisting of basic meter, SMGW and control box from a single source
- High processing performance for complex installation scenarios
- An optionally available incorrect installation protection prevents typical assembly mishaps
- Independent TLS-protected Ethernet IP port for WAN connectivity
- Real-time clock for accurate timestamps up to 5 days
- Sustainability through short delivery routes and production in Thuringia
- High-frequency counter values on the HAN interface
- Interoperability with numerous commercially available meters in the electricity, gas, water and heating sectors (* please note our information on this)
Properties
The following properties are characteristic of this high-security product:
- Conformity to FNN specifications SMGW, BSI-CC-PP-0073-2014, BSI TR-030 TR-03109-1 v1.1, PTB-A50.8
- Integrated security module with legal certification ensures cryptographic security and highly secure communication
- Three independent Ethernet IP interface for WAN connectivity, HAN connectivity and CLS connectivity
- Integrated WEB server to provide data to end users via HAN interface
- TLS protected RS 485 / HDLC bus interface for connecting meters
- Secure wM-Bus radio interface according to the OMS standard for connecting meters of all types
- Mobile authentication through inserted Mini-SIM (2FF) or eSIM (from SGH-S v2.00 onwards)
Applications
Highly secure communication gateway for intelligent measurement systems, network management
In combination with the system-capable basic meter SGM-D4, the secure communication gateway SGH-S forms an intelligent measurement system “iMSys”. Customers with load management, heating control and EEG supply will in future be able to use the GCU-S control box as an additional component, which will be connected to the control center via the CLS interface of the smart meter gateway.
The SGH-S gateway and the associated GCU-S control box can be integrated into the basic meter as components of the Smart Energy portfolio. Together they form the basis for customer management, efficient energy use and automation in modern distribution networks (smart grid).
Other areas of application include building automation and resource management in commercial and industrial companies, where the SGH-S can be used as a secure communication node.
Features
The functionality of the device can be designed flexibly through a highly secure firmware upgrade and by separating the firmware into a fixed domain that can be changed over the operating period.
The following functions are available as standard:
- Real-time clock, time synchronization via NTP server, time stamping
- Self-monitoring and testing (system/operation log)
- Supported tariff use cases:
- TAF-1: Data-saving tariffs
- TAF-2: Time-variable tariffs
- TAF-6: retrieval if necessary
- TAF-7: Meter reading measurement for variable tariffing
- TAF-9: Retrieval of the actual feed-in of a generation plant
- TAF-10: Retrieval of network status data
- TAF-14: High-frequency measurement provision for value-added services
- Simultaneous connection of up to 40 wireless and 10 wired meters
From SGH-S v2.00 onwards, the following additional functions are available:
- Compact profile wM-Bus
- Supporting the LwM2M protocol (NMS-ready)
- Crypto reset with SYM messages
- “Control from SMGW”-ready
- “TR v2.0”-ready
- eSIM ready
