1. Description

The MCF-LW13IO is a LoRaWAN® actuator that allows to switch ON and OFF a 230Vac~, 8A load. It also reads the status of a 230Vac~ input. This device can transmit the status of its input and control the output through the LoRaWAN® network. It can be used for industrial process control and home automation, water treatment, agriculture irrigation and similar applications. Input can be used as pulse counter.

2.2 Installation

The installation has to be done by a qualified electrician.

The device is intended as subassembly (component).

It is responsibility of the assembler of equipment incorporating to ensure that the overall equipment is safe.

The MCF-LW13IO must be mounted in vertical position.

Please refer to following connections:

Name Description
L LINE Device power supply: 110÷230Vac~ Live
N LINE Device power supply: 110÷230Vac~ Neutral
L IN Digital Input monitor: 110÷230Vac~ Live
N IN Digital Input monitor: 110÷230Vac~ Neutral
C Terminal for Common contact
NC Terminal for Normally Close contact
NO Terminal for Normally Open contact

Caution: NIN and NLINE are internally connected.

The device must be placed where the LoRaWAN® signal coverage is good (SF = 7 optimal, SF = 12 weak).

2.3 Power supply

Connect the power supply to pins L LINE and N LINE. Valid range is 100Vac~ to 240Vac~ 50/60Hz.

2.4 Configuration

To deploy the sensor, download the latest LoRa Tool Android App to setup LoRaWAN® credentials and other preferences :


Move the NFC antenna of the mobile (the exact position varies depending on the model of the smartphone) to the sensor antenna, in the area shown in the figure:

To use the NFC interface, the device must be powered through terminals L LINE and N LINE. The power status is visible on the red/green led.

Always validate your settings by reading the NFC data after the sensor has restarted.

Configuration can be done only via NFC. No USB port available.

2.6 Firmware update

Download the latest firmwares available on the smartphone with LoRaTool app:

Update the sensor with LoRaTool:

During the update, do not move the smartphone untill the end message.

3 I/O

As default, the device sends a message every time an input or an output changes.

A downlink with new output status forces the device to send back an unplink with the new status. If the output status is the same of current one, the sensor will not send back any message.

Downlink examples (hex):

turn ON the output: 0400 0100 0000 0000 0000
turn off the output: 0400 0000 0000 0100 0000
receive the current status: 0400 0000 0000 0000 0000

Is possible to set a period (in minutes) to receive a recurrent periodic message with the I/O status.

3.1 Input

Off voltage 0÷2Vac 50/60Hz
On Voltage > 8Vac 50/60Hz
Maximum input voltage 250Vac 50/60Hz
Input current 5mA typ
Max frequency (as counter) 2 Hz
Optoinsulation NONE

Caution: NIN and NLINE are internally connected.

Input can be used as pulse counters (see settings chapter).

3.2 Output

Contact mode SPDT
Max. power commutable 2000VA
Maximum switching voltage 250Vac~
Max. current 8A


The output has pulse capability (minimum pulse duration is 100ms, maximum around 100 minutes), so, instead to send two different commands (one to turn on and one to turn off the ouput), is possible to send a duration command.
As application example, to safely turn on an output, send a ON-pulse command for a defined time (for example, for the maximum allowed interval), and before the expiring time, another ON-pulse command (making a kind of watchdog) if the output still needs to be ON, or a simply OFF command if you want to turn it off.

3.2.1 Time schedule

It is possible to program the device with a weekly calendar, based on day of the week and time, to turn ON and OFF the output at a defined time:



and generate and XLS file that can be downloaded by downlinks:


3.3 Wiring examples

Load connected to the same supply of the sensor, connected to the relay output (normally open contact):

Load connected to an auxiliary power supply (AC or DC), connected to the relay output (normally open contact), and a switch connected the digital input :

4 LoRaWAN® network

The sensor is compliant with LoRaWAN® specification 1.0.2, regional 1.0.2b.

4.1 Activation

The device supports the following activations on a LoRaWAN® network:

  1. NONE: sensor not activated
  2. OTAA: the JoinEUI and the AppKey not setted, must be written to the device;
  3. OTAA MCF88: Over the air activation, fixed keys: JoinEUI = 904e915000000003, AppKey on request;
  4. OTAA ENGINKO: Over the air activation, fixed keys: JoinEUI = 904e915000000003, AppKey on request;
  5. ABP: requires writing to the device of NwkSkey, AppSkey, DevAddr.

The device exits factory activated with NONE mode. On request devices can be shipped aleady activated.

Note: in OTAA AppKey is write only, in reading the field will always be empty, even if set.

4.2 Other settings

Network settings:
please keep “Any” settings. Change it only if Objenious network is used (default_ any).

Network type:
LoRa syncword can be setted as “private”(0x12) instead “public” (0x34), but the NS must be setted accordingly (default: public).

select the right LoRaWAN ® band settings accodingly to country requirements.

set to force a change of the output (default: off).

set to change DST (default: none).

No time sync:
set to disable time synchronization request (default: enabled).

Normally sensor asks for a time sync at every power on (uplink starting with 01) or, if enabled, once a week.

Please check chapter 2.1 DATA FRAME FORMAT.

set for unconfirmed uplinks (default: confirmed uplink).

Led Off:
set to disable the system leds (default: enabled).

Input counter:
set to enable the pulses counter funcion (default: disabled).

Single join/day:
set for to allow only one join per day (default: multiple join allowed).

Counters period [min]:
if counter enabled, this is the interval (in minutes) between one measure and the next one. The sensor sends one measures for every transmission. Value can be between 1 and 255 minutes (default: 0 minutes). Period interval can be set with App or with downlink command.

I/O period [min]:
if different from 0, this is the interval (in minutes) between one I/O messages status and the next one. Value can be between 1 and 255 minutes (default: 0 minutes - disabled). Period interval can be set with App or with downlink command.

5 Passwords

The device can be protected by passwords, to avoid unauthorized persons to read data or modify parameters.

As default passwords are equal to 0.

Allowed values range from 0 to 999999999 (only numbers).

To change the passwords, set the new values with the LoRa Tool App:

Once the passwords are setted, to gain access from LoRa Tool to the sensor, open the App:

and set the right values before reading from the device:

To bring back the sensor to factory default and reset the passwords, a reset code must be requested to enginko (please provide the DevEUI of the sensor when you ask for that code).

6 Configuration file

WIth LoRa Tool App is possible to configure the device using an XML file, instead to manually adjust the parameters (for details about the file format please ask to enginko). This is very useful especially in case of multiple devices configuration.

With “Save” button an XML file with the actual configuration of the sensor will be generated. This is useful to store or clone the configuration, or to send it to enginko's support if needed.

6.1 Multi devices configuration

WIth LoRa Tool App is possible to configure many devices in an easy way.

For multi-configuration is needed at least one XML file with the parameters to set.

Settings on this file will be applied to all the sensors.

With an additional XLS file is possible to load different LoRa configuration parameters (Activation Type, AppKey, AppEUI, NetKey, DevAddress, Band, Private option) for each sensor, based on DevEUI.

When the sensor is approached, if one parameter is different from files, the APP will ask you if you want to overwrite.

XLS is prevailing on the XML, so if both files are enabled, if the DevEUI of the device matches one of the DevEUIs in the XLS file, LoRa parameters will be setted from this one.

These configuration can be done in the in the Settings:

  • Enable or disable the use of the general configuration by file;
  • Enable or disable the use of the specific configuration by file;
  • Verify the passwords;
  • Writing the passwords.

For details on files format please ask to enginko.
