To ensure correct operation and reliable and consistent measurements, install the EGK-LW22CCM 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.

The fasteners and substrate surfaces should have equilibrated for a minimum of 1 hour at temperatures of 68°F (20°C) or greater before application. These adhesive backed fasteners should be applied to surfaces that are smooth, dry and free of oils, mold release agents or other surface contaminants. The substrate should be cleaned with an appropriate cleaning method for the customers substrate(s) and surface contaminant(s).

NOTE: Be sure to follow the manufacturer’s precautions and directions for use when using solvents, or other cleaning method.

Remove the liner and without touching the adhesive, apply the fastener the surfaces using firm roller pressure to help ensure complete adhesive contact to the substrate. The pressure-sensitive adhesive bonds on contact and parts can be handled immediately. Adhesive bond strength increases with time, pressure and temperature. A minimum of twenty four (24) hours dwell is recommended before applying a load or disengaging. Recommended time to achieve maximum bond strength is 72 hours (3 days).

For special applications or to secure the device in a stable manner, optional wall mount bracket EGK-RAWALL is available:

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 smartphone 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:

or pressing the push button for more than 5 seconds.

The function of the button changes depending on how long it is pressed:

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

EGK-LW22CCM is provided with two CR123A batteries.

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 from the board and put the new ones:

• 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 Angel4Future (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. When in no Log mode , the sensor sends one to three measures (settable) for every transmission. Value can be between 10 and 65535 minutes (default: 10 minutes)

When in Log mode , the device makes and save one measure every time interval setted in the Measurement Period setting. When the measure number reaches the Samples Number value, the device will send this measure:

Example: if Samples Number is 10, and Measurement Period is 1, the device will send to the LoRaWAN network 1 uplink every 10 minute. All the measures will be saved in the log file.

Period interval and samples number can be set with App or with downlink command.

The EGK-LW22CCM, in Log mode, can store up to 3000 measures.

This is a circular buffer, that means that first starts out empty and when it is full and a subsequent write is performed, then it starts overwriting the oldest data.

Each sample contains these information:

• #: position in the buffer
• Date: timestamp of the measure
• Temperature [°C]: temperature value
• Humidity [%rH]: humidity value
• Battery [%]: battery level
• Sent: No if the measure had to be only stored, Yes if had to be sent
• Sent OK: Yes if the measure was correctly with an uplink, No if for some reason it was not possible to send it
• Timesync needed: Yes if time synchronization is older than 1 week

Buffer data can be retrieved by LoRaTOOL App:

Store data can be also downloaded by LoRaWEB application or with downlinks/uplinks via LoRaWAN networks:

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 MCF88: 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 OTAA ENGINKO 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 Angel4Future Srl (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 Angel4Future). 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 Angel4Future'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 Angel4Future.
