To ensure correct operation and reliable and consistent measurements, install the EGK-LW22TWP00 sensor away from direct sunlight and rain.
The device must be placed where the LoRaWAN® signal coverage is good (SF = 7 optimal, SF = 12 weak). The sensor can be installed on the wall or pole using the included accessories.

Custom brackets available on request.

For mounting onto wall, use the optional wall mount bracket EGK-RAWALL:

For installation on poles, pillars or posts use the included bracket and fasteners:

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

Enable the Bluetooth on the smartphobne and open the App:

once the sensors list appears (as BLE MAC address), select the sensor you need to configure:

and read it:

The sensor is shipped completely off to prevent battery consumption during storage. It is therefore necessary to carry out a first power-on prior to commissioning.

To power on the sensor: lay the magnet at the bottom of the provided tool into the area shown in the figure:

Successful power on is signaled by the flashing of the 2 LEDs.

In case of long period of inactivity, if necessary, is possible to shut-off again the sensor to prevent battery consumption, via downlink or with LoRa Tool App:

This sensor contains lithium battery, which must be disposed of separately.

EGK-LW22TWP00 is provided with a replaceable battery pack:

Replacement battery only available from enginko.

This is the estimated battery life (in years) in the worst conditions:

• remove the front panel of the sensor with a small hex key (for M2.5 bolts):

• remove the PCB batteries pack from the main board (PCB board is secured with two small screws):

• Place the new PCB batteries pack and put them in place with the screws:

• Place the front panel and fix it with the 4 bolts.

After the batteries replacement, internal counters need to be resetted.

To perform the operation, you need a unique reset code that must be requested to enginko (please provide the DevEUI of the sensor when you ask for that code):

At the end of the procedure the battery level displays 100%.

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.

Period is the interval (in minutes) between one measure and the next one. The sensor sends three measures for every transmission. Value can be between 10 and 65535 minutes (default: 10 minutes).

Period interval can be set with App or with downlink command.

When the sensor is not installed at the sea level, the reading of barometric pressures at other elevations must be compensated. Set the right altitude value with LoRa Tool app:

Value can be from -300 to 3000 meters.

Altitude can also be set with downlink command.

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

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 ENGINKO: Over the air activation, fixed keys: JoinEUI = 904e915000000001, AppKey on request;
4. OTAA ENGINKO: Over the air activation, fixed keys: JoinEUI = 904e915000000001, 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.

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).

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

DST: set to change DST (default: none).

UTC time: set to enable UTC(default: disable).

Time sync: set to enable 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.

If not handled in the right way can cause a unnecessary battery consumption (battery life < 2 years).

Please check chapter 2.1 DATA FRAME FORMAT

UnConfirmed: set for unconfirmed uplinks (default: confirmed uplink).

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

System led: set to turn on the system leds (default: system led on).

Clock timed: set to syncronize the measures to the nearest portion of the hour (default: no clock timed).

Example Period: 10 minutes.

• No clock timed

Mesures: 10:08, 10:18, 10:28, 10:38, 10:48, 10:58

• Clock timed

Measures: 10:10, 10:20, 10:30, 10:40, 10:50, 11:00

Please be careful: with this setting enabled sensors send uplinks simultaneously.

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).

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.

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.

enginko provides, upon free registration, LoRaWEB online tool, where for each sensor it is possible to find documentation, javascript examples for parsing, downlink generator and uplink decoder:
