To complement the meters of the Smart Energy family, EFR offers accessory modules for some models that can be integrated in the case to extend the functional scope. A number of LMN adapters and tariffing modules are available.
The LMN adapters allow modern metering devices to be securely connected to a smart meter gateway in accordance with the provisions of the Measuring Point Operation Act (MsbG) and the BSI. For the new generation modular meters, tariffing modules are available to implement a dual tariff function with suitable configuration of the meter.
