4 Function and device
overview
The Homematic IP interface for energy
sensors is a battery-powered wireless
module for integrating energy me-
ters into Homematic IP installations. It
is used for acquiring the energy data
from electricity meters.
The LED energy sensor detects LEDs
flashing in the visible light spectrum as
well as infra-red LEDs. Pulse LEDs on
most meters can be identified because
they are labelled with the pulse con-
stant or the designation RL. However,
we only recommend using the device
on meters with one direction of energy
flow, because the values of a bidirec-
tional meter cannot be fully repro-
duced via a pulse LED.

With very small loads, there are
not enough pulses available per
transmission interval to calculate
the power value, which then be-
comes unsteady. The limits are
approximately:
Imp/kWh
500
800
1,000
2,000
5,000
10,000
100,000
We only recommend using the
device on meters with one direc-
tion of energy flow. The values of
a bidirectional meter cannot be
fully reproduced via a pulse LED.
