Smart Meter Gateway CONEXA 3.0

Since summer 2013 we are working on the Smart Meter Gateway CONEXA 3.0, which has been undergoing certification by BSI.

During this german certification process the requirements of the BSI (Bundesamt für Sicherheit in der Informationstechnik) Protecion Profile BSI-CC-PP-0073 for Smart Meter Gateways, TR 03109, PTB-A 50.8 and FNN specifications are all taken into account.



  • Order No. 0100300
  • Can be updated for certified functions for mains and energy distribution
  • In the future also suited for CLS components (Controllable Local Systems) and Smart Grids
  • Transfer from meter to CONEXA via wM-Bus (OMS with AFL4.0, Mode 7) and serial via RS485
  • Transfer of data to the administrator via XML (COSEM/https-Webservices) standard via Ethernet, Powerline via Ethernet, mobile radio, MMTS, GPRS, or in the course of 2016, also for LTE
  • Integrated standard interfaces for WAN, LMN, HAN, and CLS
  • Multi-client capability for apartment buildings
  • Multi utility for applications in the field of electricity, gas, water, heat
