What is HWg-PWR
HWg-PWR is an Ethernet-enabled device for remote monitoring and metering of
electricity, heat, water or gas consumption using electricity, water, gas, heat, or other
meters equipped with the M-Bus interface. In addition to metering, the device also
supports alarming through e-mail or SNMP traps whenever allowed values are exceeded.
HWg-PWR is designed for remote reading of values from meters equipped with the M-Bus
interface. Each meter can provide multiple variables, depending on the meter type and
model. Typically, electricity meters provide the total electricity consumption and also the
immediate value at the time of reading, line voltage and/or line current; water meters
indicate total water consumption as well as immediate consumption or liquid flow rate;
and so on.
Note: HWg-PWR is designed to be universal; hence, all discovered values are read out
from every connected meter, until a specified limit is reached. To improve user comfort, it
is possible to enable or disable each discovered value (disabled value is hidden from view),
and to turn on or off the recording of measured readings for each enabled value (in order
to increase the available recording time for the remaining values).
The M-Bus protocol allows to read value names, units, or tariff information from the
meters. The user can customize all of these data (e.g. change the unit of measurement or
its multiplier).
Usage examples

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
