Landis+Gyr E320 smart meter

The Landis+Gyr E320 is a modern electronic household meter, or 'smart meter,' designed for measuring electricity consumption and generation. Landis+Gyr, the brand behind this product, has a legacy dating back to 1896 in Switzerland, where it was founded as Electrotechnisches Institut Theiler & Co.

Manufacturing of these specific modules typically occurs at Landis+Gyr’s major production facilities in Corinth, Greece, though the company maintains a global manufacturing footprint. The product shown features a 'DE-M' marking, indicating it is specifically calibrated and certified for the German market in accordance with European and German measurement standards.

Since 2011, Landis+Gyr has been a subsidiary of the Japanese conglomerate Toshiba Corporation. It transitioned into a publicly listed company on the SIX Swiss Exchange in 2017 but remains heavily influenced by its corporate history and majority shareholders. The device in the image also contains a 'Theben CONEXA 3.0' Smart Meter Gateway, which is a German-made communication module designed to transmit data securely.
