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.
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).

HWg-PWR 3 / 12 / 25 – Energy monitoring gateway:
- 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
Advantages of using third-party M-Bus meters

Specifications
Ordering Information and Accessoires
- 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.
Applications
- Remote monitoring of electricity meters in small server rooms and BTS
- Monitoring of energy consumption in rented premises
- Reading out energy consumption in remote or inaccessible areas
- Control over energy costs
- Checking for individual line overloads in three-phase wirings
- Checking for undervoltage in electric wirings
- Monitoring the flow of liquids
Collecting data from 1 to 25 M-Bus electricity meters
- 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
- 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
- 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
- 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.
