M-Bus Gateway

The smart-me M-Bus Gateway reads all energy meters with the M-Bus interface according to EN 13757-2, -3. Since it uses the existing WLAN network, no additional hardware needs to be installed. The meter data for the various energy sources (water, heat, gas, temperature) are transferred directly to the smart-me cloud and can be used in the smart-me energy management system.

Functions

  • M-Bus Gateway to the smart-me cloud

  • Integrated level converter for 50 M-Bus energy meters (up to 100 slaves with repeater)

  • Integrated power supply unit

  • Support of all M-Bus devices according to EN13757-2, -3 (former EN1424-3)

  • Encrypted Wi-Fi connection directly to the smart-me cloud

  • Integrated data logger and automatic synchronisation in case of connection failures to the cloud

  • The smart-me Cloud enables extensive energy management, including live energy monitoring, automatic invoicing, remote controlling and alarms

  • Easy installation using the free smart-me app available for Android and iOS
