TOOLS
Recording wireless telegrams
with the eNet server
The eNet server can be used to
record the eNet transmitters’
wireless telegrams and to display
them along with the time and date
in eNet SMART HOME connect,
the commissioning interface. It is
also possible to export all the re-
corded telegrams in order to run
an evaluation with another piece
of software. In the process, time
stamps and additional project data
are added to the telegrams:
• Time at which the eNet server
received the telegram
• Device UID, a freely allocated
number that is allocated in a de-
vice-specific manner
• The device’s serial number,
which can also be viewed in the
Information window
• Device type, as an abbreviation
of the device name
• Device name, which is also
shown in the device display
• Device location and device
designation
• Channel number, type, location
and name of the device channel
that sent the telegram
• Indication as to whether the tel-
egram was received by a repeat-
er
eNet diagnostic device
A simple tool is made available
for the installation engineer in the
form of the eNet diagnostic tool.
The eNet diagnostic device can be
used to detect external wireless
communication in the 868.3 MHz
frequency range, receive tele-
grams from wireless transmitters
and repeaters, and also receive
status messages from wireless ac-
tuators and evaluate them in terms
of their signal strength.
The device provides support dur-
ing the manual commissioning of
an eNet installation by helping to
evaluate the building conditions
before and during commissioning.
Installation locations can be evalu-
ated and dead spots can be detect-
ed using the diagnostic device. The
device can also help with optimal-
ly positioning a repeater and with
switching the repeater function of
mains-supplied eNet devices on
and off.
Determining the wireless signal
strength with the eNet server
If a wireless signal is attenuat-
ed too much, the signal strength
upon reaching the receiver is no
longer sufficient for error-free re-
ception. The attenuation of wire-
less signals depends on:
• The power effectively radiated by
the transmitter
• The transmission path
• The height of the antenna and
the alignment of the transmitter
and receiver
• Overlapping due to reflected sig-
nals
To assess a wireless link, the eNet
server can determine the signal
strength of received telegrams.
The measurement process itself
is carried out by the receiving eNet
devices. Connections between one
transmitter and up to four receiv-
ers can be assessed at the same
time in a single step. The eNet
server controls the diagnostic
function workflow after first se-
lecting transmitters and receivers
in the commissioning interface.
The result is shown in three levels:
• No reception
• Sufficient reception
• Good reception
If the signal strength does not
meet the requirements, measures
should be taken to improve the
wireless link, such as changing
the installation location, using re-
peaters, minimising interfering in-
terfaces caused by metallic parts
or other devices, etc.
For wireless connections of “suf-
ficient” quality, it should if nec-
essary be critically considered
whether influences that are still
impossible to predict during the
construction phase may impair
the quality of the wireless connec-
tion. If, for instance, the building
owner prefers metal furniture in
a meeting room, or if a side room
