1 Overview
ThingsLog LPMDL-1102 is a universal, low power mobile data logger able to meter various kinds of pulse
meters and analog sensors. The logger is transmitting the metered data over 4G/NB IoT.
LPMDL-1102 has the following key characteristics:
Optimal data transmissions - LPMDL-1102 is able to transmit the data over a two way 4G/NB IoT network in
an optimal for the battery way. That allows the logger to meter per minute, to transmit a couple of times per
day and still to achieve more than 10 years of battery life.
Intelligence - the data is transmitted over a widely distributed, cellular network and is automatically
gathered in ThingsLog platform.
Pulse metering -LPMDL-1102 has ability for an independent counting of pulse output meters for water, gas,
power and heating. With a single data logger you can meter two meters for example for cold and hot water
or if your meters are in proximity distance you can meter with a single device gas, power and heating.
Analog sensors metering - LPMDL-1102 has two extra inputs for connecting analog sensors with 4-20 mA
output. An example could be connecting two pressure sensors or one pressure and one temperature sensor.
Combined monitoring - LPMDL-1102 can fulfill use cases where with a single logger have to be monitored
one water meter and two pressure sensors. For example monitoring of pressure reduction areas by
measurements of pressure sensors before and after the pressure reduction valve and its water meter.
Alarms and notifications - LPMDL-1102 together with the ThingsLog platform is able to monitor
consumption and notify the customer or the utility company for leaks, high or low consumption, fraud or
thresholds bridging of certain sensor value or a combination of a sensor and metered value.
Application - LPMDL-1102 fulfills various use-cases in water, power and gas distribution utilities but also
many other use-cases in property management, hotel, manufacturing, condominium sub-metering or in
common need is spread.
Ability to work in any environment -LPMDL-1102 has IP68 dust and leakage protection and is suitable for
any kind of home or industrial usage.

●Prior to install the logger please review the health and safety instructions described in chapter 3.
●The data logger is coming with an installation manual and a kit through which it can be attached
to a firm surface.
●In order to attach the logger you will need a wall with stiff, flat surface close to the meter or the
sensor which you would like to measure.
●Mark and drill holes with size 4x25 mm for attaching the logger to the wall.
●Attach the logger input/outputs to the connecting cable.
●Attach the corresponding connecting cable input/outputs to the meters/sensors.
6 Input/Output ports
LPMDL-1102 has 12 input/output ports. To access the ports unscrew the board from the bottom of the
logger enclosure and lift it up.

for battery replacement.
8 User guide
8.1 Associating logger to a profile
1. In order to perform the initial configuration you should have an account for ThingsLog IoT platform. If
you don’t have an account please go to https://iot.thingslog.com/signup and register to the platform.
2. Once registered go to Downloads section or directly visit https://iot.thingslog.com/thingslog.apk in
order to get Thingslog Andriod Application.
3. Login into the Andorid app with your username and password.
4. Scan the QR code on the logger label.
Visit us at www.thingslog.com; ([phone]; [email protected]

Figure 6 Area to be scanned
5. If the scan is successful the android app will be able to register your logger to your profile. Note that
you can register once logger to only once. If you want to register the device to another profile please
contact us at [email protected].
6. Once the device is registered you can continue with the initial configuration.
8.2 Network coverage and service
In order to work ThingsLog data loggers need network connection. Prior performing the initial
configuration ensure that there is NB IoT network coverage in your area. If you are not sure which network
operator has been used with your ThingsLog device please contact us at [email protected].
8.3 Initial configuration ThingsLog LPMDL-1102
1. Connect your logger to your meters and sensors as described in section physical installation.
2. Navigate to meny “All Devices” - and pick your newly added logger.
Visit us at www.thingslog.com; ([phone]; [email protected]

Figure 7 Menu “Devices”
3. From the menu choose “Config” then a similar configuration dialog will appear.
Figure 8 Configuration dialog
Visit us at www.thingslog.com; ([phone]; [email protected]

On the top you can see the logger id, date when it was configured for a last time and current
configuration status.
Then follows the common section for all inputs/outputs.
●Counts threshold  - Number of counter/sensor readings to store in memory. Once that number is
reached a transmission will happen
●Record period  - Could be Minute, Hour or Day. This is the period on which the logger will log in
memory the reading values from the pulse inputs or the period on which it will perform low
power reading of its analog current inputs.
●Every  - Frequency of reading - could be 1,2,3,5,10,15,20,30 in the measurement time unit
selected in “Record period”
4. For each pulse sensor (a meter connected to a pulse input) slide the slider to the right and enter:
●Digits  - Number of digits - equals to the number of digits on the display of the meter
●Fraction  - Number of digits after the decimal pointer on the display of the meter
●Initial counter  - Initial value of the counter of the meter
5. To enable analog sensor readings (connected to the analog inputs) just slide the slider to the right
6. Delete old counters  - once you are ready with the inputs configuration decide do you want to keep
the old values or not. If not choose “NO” else chose “YES”.
7. Once you are ready press “Start Setup” button.
This will start a 1000 seconds counter. You will have to touch the logger with a magnet prior the counter
expiry. This will put the logger into configuration mode and it will try to obtain its configuration from the
server.
8. If the logger is able to do so you will be able to see the following message on your screen.

If the configuration process is unsuccessful and the device stays in “Not configured” mode please
ensure that the device has been placed in an area with propper NB IoT coverage. If you are not sure that such
is available in your area please let us know at [email protected]. But please note that if there is no NB
IoT signal there are only a few things you can do.

supports the following kinds of alarms:
●NO_ZERO_CONSUMPTION - alarm for non zero consumption. The non zero consumption is defined
as condition in which the logger is detecting consumption over certain threshold over certain long
period of time. For example the logger has detected a NON zero consumption over 6 consecutive
hours.
●HIGH_CONSUMPTION - alarm indicating consumption higher than a certain preconfigured level over
certain period of time. For example 1m
3
over 1 hour.
●MISSED_TRANSMISSION - alarm indicating that the transmission from the logger did not happen.
Visit us at www.thingslog.com; ([phone]; [email protected]

●LOW_CONSUMPTION - alarm indicating that the consumption for certain time interval is lower than
the expected one.
●ALL_ZERO_CONSUMPTION - alarm signaling zero consumption through certain time period. For
there is no consumption for 24 hours. Could potentially indicate a fault meter.
●DEVICE_REMOVED - alarm indicating that the meter has been disconnected from the logger.
●LOW_BATTERY - alarm indicating that the battery of the logger is under 20%.
