1INTRODUCTION
This document describes the usage of the SmartPlug device. It is necessary to read the “LoRaWAN Sensors
Application Layer Description” for the applicative layer presentation and the “LoRaWAN Sensors Behavior on
Public LoRaWAN Networks” for the network layer in prerequisite for all generic information.
2START-UP
The SmartPlug uses the main voltage as a power supply. In order to switch it on, plug it into a wall socket. The
SmartPlug will automatically start.
Here below can be seen illustrations of the SmartPlug in the Europe version and in the US version.

CAUTION: This is a device connected to the mains power source, do not open the boxing while the
device is running
The SmartPlug remote is not waterproof. Thus, it has to be protected from the water splash and
cannot be used in bathrooms.
Once plugged, the SmartPlug led will flash green. As long as the SmartPlug is not paired with the LoRaWAN
network, the led will flash (cf. “LoRaWAN Sensors Behavior on Public LoRaWAN Networks” document). Once
the device is correctly paired, the led will stop flashing.

3USE CASES
3.1 FIRST USE:CONTROLLING ELECTRIC DEVICES IN ON/OFF
The direct application for the SmartPlug is to control electrical devices thanks to their electric supplies. Indeed
the SmartPlug is plugged inside a wall socket. Then the device to control has to be plugged on the SmartPlug’s
socket, as it can be seen on the picture here below.
Once this quick installation is done, the electric device can be controlled through the LoRaWAN network to be
either powered or not. This control is done thanks to the ZCL: the nke Watteco’s application layer. More
precisely, thanks to the On/Off cluster (cf. “LoRaWAN Sensors Application Layer Description” document p.22).
The exact frame to send can be found in the paragraph §5.
3.2 SECOND USE:WATCHING THE CONSUMPTION OF ELECTRIC DEVICES
Controlling an electric device in On/Off is, of course, not the only application for the SmartPlug. Indeed, this
latter integrate the necessary electronic to measure the power consumption of the electric device plugged on
it.
All the measured value can be found iniside the Simple-Metering Like Cluster (cf. “LoRaWAN Sensors
Application Layer Description” document p.29 and 30). Here below can be seen a table summarizing all the
value measured along with their unit.

CAUTION: The maximum power that the SmartPlug can commute is 16 A for the European version
and 15 A for the US version. Please be careful to not exceed these limits.
3.3 THIRD USE:WATCHING THE QUALITY OF THE ELECTRICAL MAIN
Finally, the SmartPlug integrates as well the electronic necessary to measure and evaluate the quality of the
electrical main where it is plugged to.
In the array here below, are listed the available indicators provided by the SmartPlug to evaluate the quality of
the main. These measures are located inside the Power Quality cluster (cf. “LoRaWAN Sensors Application
Layer Description” document p.31 and 32).

4HUMAN MACHINE INTERFACE
One led can be seen on the device (cf. picture in §2). This led can have 3 different colors
Green: blinking until the association to a network is done.
Red: not used for the moment
Orange: blinking 3 time on a reset factory
A user button can be seen as well on the picture in the paragraph §2. When the utton is pressed for a long time
(7 to 8 second, until the orange led blink), the orange led will blink 3 times and a “Reset Factory” is done. To
complete the “Reset Factory” the device needs to be reboot (unplug and plug the SmartPlug will do a correct
reboot).
A “Reset Factory” allows to delete all the applicative configurations saved in the device (report configuration,
batch configuration, etc.) and to delete some LoRaWAN configurations as the channel masks or the channels
added thanks to the NewChannelsReq Mac command.

5APPLICATIVE LAYER
The SmartPlug device is an awake device. It implements the “On/Off” cluster associated with the output
controlled by relay, the “Power Quality” cluster and the “Simple-Metering-Like” cluster.

5.1 EXAMPLES
Herebelow are some examples of sending an On/Off order to the SmartPlug or configuring a report or a batch
on either the “Simple Metering” Cluster or on the “Power Quality” cluster. If you want more informations
about the applicative layer, please refer to the “LoRaWAN Sensors Application Layer Description” document.
In the following examples, the 6lowpan header has been removed for an easier understanding. See
6LOWPAN LAYER OVER LORAWAN™ in the LoRaWAN Sensors Behavior on Public LoRaWAN Networks guide,
for more details.
5.1.1 ON/OFF COMMAND
Specification: Supply or unsupply the electric device plugged on the SmartPlug in electricity.
Solution: As there is only one On/Off output, the End Point is 0 and Cluster “On/Off” is 0x0006. The
frame to send to apply the On or the Off is a cluster command from the On/Off cluster.
Applicative payload are:
1150000600 Command OFF
1150000601 Command ON
1150000602 Command TOGGLE
5.1.2 CONFIGURE A STANDARD REPORT ON THE POWER QUALITY CLUSTER
Specification: Report all the measures allowing to evaluate the Power Quality (F, Fmin, Fmax, Vrms, Vrms
min., Vrms max., Vpeak, Vpeak min., Vpeak max., Over-Voltage Number, Sag. Number and Brownout Number).
These values has to be reported at less each 20 minutes and a minimum timing of 1 minute between 2 reports
has to be setted. Finally, an increase or a decrease of 10Vrms has to trigger a report. All other delta on the
values should not trigger a report.
Solution: As there is only one measurement input, the End Point is 0, cluster “Power Quality” is 0x8052
and attribut “Current” is 0x0000. The maximum field has to be 0x8014 to have a report all 20 minutes and the
minimum field has to be 0x8001 to have a minimal timing of 1 min between two reports. All the 0xpppp fields
have to be configured to 0x00 in order to not trigger a report except for the Vrms measure, where a delta of
10V should trigger a report, thus the value for dVrms will be 0x0064 (because the unit is V/10).
Applicative payload is:
11068052000000418001801418000000000000006400000000000000000000000000000000

5.1.3 CONFIGURE A BATCH REPORT ON THE SIMPLE METERING LIKE CLUSTER
Specification: Timestamp and record the Active Energy and the Active Power each time it decrease or
increase of respectively 10 W.h and 100 W. A batch has to be sent at least every 3h and at maximum every 10
min. The resolution needed for both of the measure is 1 W.h and 1 W.
Solution: As there is only one measurement input, the End Point is 0, cluster “Simple Metering-Like” is
0x0052 and attribut “Current Metering” is 0x0000. Here, there are two values to record in the batch, the tag
size can be 1 (label 0 and label 1 available). For the Active Energy, the delta will be 0x00000A and resolution will
be 0x000001. For the Active Power, the delta will be 0x0064 and resolution will be 0x0001.
For both of the measure, the maximum field has to be 0x80B4 to have a report at least every 3 hours and the
minimum field has to be 0x800A to have a minimal timing of 10 min between two reports.
Applicative payload is: 110600522D000000800A80B400000A0000010103800A80B40064000109
