PWR 3/12/25
  • PWR 3/12/25

    HWg-PWR is a smart Ethernet gateway for remote energy metering and consumption monitoring. To measure the consumption of water, electricity and other energies, external meters with the M-Bus interface are used. Up to 3 / 12 / 25 M-Bus meters can be connected to the HWg-PWR unit. Individual meters (electricity meter, water meter, gas meter, heat meter etc.) are produced by third parties and connected via their M-Bus interface. HWg-PWR is a smart gateway that monitors energy consumption and warns about abnormal values The unit provides a Web interface, charts, SNMP and Modbus/TCP output, data logging, e-mail and SMS alerts, and much more.
