HWg-PWR 3/12/25: M-Bus to Ethernet gateway

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.

Additional Product Information

HWg-PWR 3/12/25 monitors energy consumption using standard external energy meters produced by well-known manufacturers. It is possible to mix electricity meters, water meters, gas meters etc. by different manufacturers. Depending on version, HWg-PWR supports 3, 12 or 25 external meters with the M-Bus interface (EN 13757).

Advantages of using third-party M-Bus meters

Vast range of meters with the EN 13757 (M-Bus) interface to choose from.

It is easy to use special-purpose meters (non-standard form factor or measured range, e.g. indirect electricity meters rated up to 1000 A).

M-Bus meters frequently provide extended information (total consumption and immediate values, voltage at different phases, power factor, etc...).

Values from certified meters can be used for billing purposes.

Support for Programmers:

HWg SDK

Supported software

HWg-PD Trigger: Control of other IP devices, alarm redirection to SMS

HWg-PDMS: Logging, export to MS Excel

Third-party SNMP software

(HP OpenView, IBM Tivoli, Nagios, Zabbix, Cacti, Monitor one, The Dude, Paessler IPCheck, Ipswitch WhatsUp, Axence nVision, CBR little:eye, LoriotPro, GFi NSM, SNMPc 7, CA NSM, ActiveXperts NM, Intellipool NM, MSC Operations Manager 2007)

Features Include:

  • Sends an alarm in the event of failure or value out of a specified range (E-mail, SNMP Trap, SMS)
  • Logs selected values (displays graphs over the WEB interface)
  • 8x Digital Inputs for detecting single-phase 110/230VAC outage
  • Converts the consumption (e.g. from [kWh] to [€]) without a computer or additional software
  • Periodically sends an energy consumption report for the given period as an e-mail attachment
  • Actively uploads data to a “portal” using the HWg-Push protocol
