Function and device overview
4 Function and device
overview
The Homematic IP interface for energy
sensors is a battery-powered wireless
module for integrating electricity me-
ters into Homematic IP installations. It
is used for acquiring all meter readings
and the latest consumption data from
the electricity meter.
The device is compatible with the serial
optical interface of meters in accord-
ance with IEC 62056-21. The IEC inter-
face corresponds to the current stand-
ard of electronic household electricity
meters. The data is acquired by the
sensor and sent to the Homematic IP
access point.

In the meter menu, activate the ex-
tended data set if this function is avail-
able. If this function is not available
on your meter, consult the operating
instructions for your meter for details.
If necessary, also request the free PIN
from the metering point operator.
Keep the PIN in a safe place so that
you can change this setting again if the
meter reverts to the reduced data set
after a power failure, for example.
The D0 Mode A to D and SML
protocols are supported. Idis CII
(Austria) is not supported. The
data transmitted includes the
current power value, meter read-
ing of incoming energy supply
during peak tariff periods, meter
reading of incoming energy sup-
ply during off-peak tariff periods,
and the meter reading of outgoing
supply. Thus, the device can be
used on feed-in meters, con-
sumption meters, bi-directional
meters, single tariff meters and
dual tariff meters. If the meter
does not provide any power val-
ues, the HmIP-ESI calculates them
from the change in the meter
readings.
The resolution depends on the
resolution of the meter readings
and is approximately:
Wh

For meter readings with a lower
resolution, the power is not calcu-
lated.
