Important notes
^This document is a quick reference guide. A sup-
plementary product description is available online at
https://doc.lobaro.com.
,The device is powered by an internal, replaceable 3.6V lithium
battery (Li-SOCl2), which is subject to transport restrictions.
Hazardous material class: 9A. The applicable transport regula-
tions must be met when transporting the device incl. inserted
battery. The battery must not be connected during transport!
The test certificates for the approved batteries are available on
request.
,This product must be installed professionally and in accordance
with the specified installation guidelines and may therefore only
be installed by trained and qualified personnel. For installa-
tion in structures with increased fire protection requirements,
e.g. staircases, escape routes, the installation company or the
qualified personnel must ensure that the specific requirements
according to local building regulations are fulfilled!
,These instructions must be read carefully before initial opera-
tion, followed and kept for the entire service life of the device.
Intended use
The Lobaro Wireless M-Bus Gateway V3 receives data telegrams from up
to 500 utility meters with standardized 868 MHz wireless M-Bus interface
and forwards them downstream via NB-IoT cellular radio or alternatively
LoRaWAN to the Internet for further processing or evaluation.
In addition to the unidirectional wireless M-Bus modes C1, T1 and S1,
the proprietary Sensus RF radio protocol is also supported by the radio
receiver in the gateway.
The previously received meter data is transferred to the Lobaro IoT plat-
form, optionally encrypted via DTLS, and can be viewed there or down-
loaded as a CSV file. Alternatively, the connection of other downstream
third-party systems via standardized APIs from the Lobaro platform is
easily possible.

,The device is intended exclusively for the aforementioned pur-
pose. An application other than previously described or a mod-
ification of the gateway are considered as non-intended use and
must be requested in writing in advance as well as specifically
approved.
Mode of operation
1. The gateway is in energy-saving mode for the majority of its operating
time.
2. The device wakes up at freely configurable intervals (’CRON param-
eters’).
3. Encrypted or unencrypted Wireless M-Bus (868 MHz) telegrams
are received for the configured time duration (among others
’cmodeDurSec parameter’) and buffered unchanged in the internal
memory.
4. Meter reception can be restricted with filters to specific device IDs,
types or ’CI fields’.
5. After the configured period of time, the collection of meter data by
radio is stopped again.
6. The data is sent via NB-IoT cellular radio or LoRaWAN to the down-
stream IoT platform or LoRaWAN network server on the Internet.
7. The platform decrypts (on demand) the consumption data with stored
keys.
8. The consumption values or meter telegrams are available in table
view, as CSV download or via standardized APIs.

Initial operation
To commission the gateway, a suitable SIM card must be inserted in the
socket at position (2) if mobile radio is to be used for data upload instead
of LoRaWAN. To do this, first slide the cover lock of the socket to the
right and then open it upwards. During insertion, it is essential to ensure
that the battery (1) is not connected. After inserting the SIM card, the
cover must be folded down and the lock must be closed again by sliding
it to the left.
The associated battery is equipped with loop tape, which is to be attached
to the velcro hooks of the device at position (8) when inserting it. Make
sure that the connecting cable of the battery is routed around the battery
body as shown in Fig.1. Then connect the plug connector of the battery
to the reverse polarity protected socket at position (1).
If the device was without power for more than 24 hours, e.g. at delivery,
it starts with the pre-configured parameters after connecting the battery
and initiates an initial collection of metering data with downstream upload
of the data via LoRaWAN or mobile radio. The device configuration of
the delivery state can be viewed via the downstream platform or was
transmitted in advance in the form of a digital delivery note.
The reset button (3) can be used at any time to reproduce the same
behavior as with the aforementioned connection of the battery after 24
hours without voltage, e.g. to start a control readout during installation
or when changing the battery.
By means of the status LEDs (4) different operating modes of the firmware
can be read. The different blinking patterns are described in the online
manual, available at https://doc.lobaro.com.
The socket for an SD card (6) is suitable for holding a corresponding
memory card. The locking mechanism works analogously to the SIM
card.
,Only 3.6V batteries approved by Lobaro may be used with the
gateway. The use of other batteries, especially without velcro
fluff, is not permitted, as there would be no sufficient protection
of the battery in the housing.
,Only antennas approved by Lobaro may be connected to the
MMCX antenna connector (7)!
ðThe storage functionality for SD cards (6) may not be supported
by all firmware versions.
ðThe SIM card used must be activated for NB-IoT or LTE-M1
networks. The gateway configuration of the LTE connection
(operator, APN, band) must match the SIM card used!
Gateway configuration
Reading and adjusting the gateway configuration is possible via the 6-pin
configuration connector (5) and the separately available Lobaro USB con-
figuration adapter in combination with the free PC-based ’Lobaro Main-
tenance Tool’ for Windows, Linux and MacOS.
Alternatively, if the network parameters are configured correctly, the con-
figuration changes can also be made ’over-the-air’ via the Lobaro IoT
platform.
ðDetails of the gateway configuration and available parameters
can be found in the online manual at https://doc.lobaro.com.
Proper mounting and housing dimensions
The cover of the gateway is secured via four quick-release screws. These
screws are loosened or tightened via a 90°turn. In addition, the housing
has a lid loss protection.
The gateway is securely fastened to a wall or ceiling with the cover open
using the four fastening points marked in red in Figure 3 and M4 screws of
suitable length. After successful wall mounting, the cover must be closed
again.
,When opening the housing lid, the quick release screws must
not be turned more than a 1/4 turn. Otherwise the screws may
break off!

Figure 2: Quick-release screws lid (open | close)
,The gateway must be securely screwed to a wall/ceiling using
four suitable M4 screws and wall anchor, cf. red marking in
figure 3.
Figure 3: Housing measurements [mm]
,When selecting the installation site, it is essential to ensure
that the specified ambient conditions (see Technical data) can
be maintained at all times.
,The mounted pressure compensation element (9) increases the
total width of the gateway from 122 mm in figure 3 to a total
of 130 mm.
ðThe pressure compensation element (9) and the IP66 housing
protection class allow the gateway to be operated outdoors.
