Smart M-Bus to Ethernet gatewaypwr

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.

Where to use

Where to use

  • External M-Bus meters (third-party products)
    • Values available over M-Bus depend on the meter – we recommend to always check the supported values with the manufacturer!
    • Support for certified and calibrated meters
    • Support for single-phase and polyphase electricity meters
    • Support for single-tariff and multi-tariff meters
    • Current transformers enable measurements of high currents
    • Examples of typically available values:
      • Instantaneous power input
      • Total consumption
      • Line voltage
      • Line current
      • Power factor (cos φ)
      • Flow speed

Collecting data from 1 to 25 M-Bus electricity meters

M-Bus electricity meters to SNMP

  • Various energy meters (equipped with the M-Bus interface) are connected to the HWg-PWR unit.
  • All values are available to external software over LAN and SNMP.
  • Energy consumption details can be viewed using the Web interface or an iPhone or Android app.
 

Server room: Energy consumption monitoring + phase outage detection

Datacenter M-Bus energy monitoring SNMP

  • Up to 25 electricity meters measure the single-phase or three-phase consumption of the cabinets.
  • Up to 8 inputs can detect phase outages.
  • When a phase fails, a warning can be e-mailed.
  • Upon an alarm (phase failure or current out of range), a text message alert can be sent to a mobile phone via an external SMS Gateway.
  • Energy consumption data can be connected to any SCADA system (Modbus/TCP) or accessed over SNMP.
 

Measuring energy consumption with S0 pulses and M-Bus meters

S0 pulses M-Bus energy metering

  • Modern electricity meters with the M-Bus interface can be connected to HWg-PWR directly.
  • Older electricity meters with a S0 pulse output can be connected using a “S0-M-Bus” converter.
  • Current consumption charts are available through the HWg-PWR web interface.
  • Every day, week or month, HWg-PWR e-mails a report. The e-mail contains a billing statement including KWh and a conversion to currency.
  • When the current consumption exceeds or drops below a set threshold, the unit sends an e-mail alert.
 

Remote energy metering with a central WEB portal

residential Energy metering M-Bus

  • Various energy meters are connected to a single HWg-PWR unit.
  • Each unit has a WEB interface for configuration, viewing logs, etc.
  • All consumption data are uploaded to a central portal using the HWg-Push protocol.
  • The central portal (e.g. SensDesk) generates detailed analyses and statistics concerning energy consumption.
