The HWg-PWR is a smart Ethernet gateway for remote energy metering and consumption monitoring.

The HWg-PWR measures 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.

Case Study 33: S0 pulse counter with SNMP and Modbus/TCP output

Case study on connecting electricity, gas or water meters to the Ethernet and reading values over the SNMP or Modbus/TCP protocols. Pulse outputs from 3rd party meters (S0 interface) are connected to the Damocles Ethernet I/O unit. Each Digital Input on the Damocles unit features a 32-bit pulse counter. The value of this counter can be read out over the web using most M2M protocols (SNMP, XML, Modbus/TCP).

Case Study: GSM temperature monitoring and logging, e-mail alerts over GPRS

Portable solution for remote temperature monitoring and logging, suitable for monitoring rooms or equipment. Excessive temperature sensed by a probe is signaled by a SMS or a ring. GSM thermometer Ares12 continuously logs the temperature in its internal memory and periodically e-mails the log over GPRS. The logs can be imported to MS Excel.

HWg-Push Nagios collector

Nagios application for collecting data from IP sensors that support the HWg-Push protocol. Thanks to the application, the Nagios SNMP monitoring system can include sensors in GSM networks or behind firewalls.
