Page 3: Product Overview
Product overview Product description Efento NB-IoT sensors transmit the data over cellular networks (Narrowband IoT) and do not require any additional devices (router, gateway, etc.). Sensors are also equipped with Bluetooth Low Energy interface, what allows quick and easy configuration with a smartphone. - Page 4 Probes length (for sensor with probes only): by default 1 meter, other lengths are available on request Operating range: -35°C to +70°C Mounting: double side adhesive tape with acrylic glue or 2 x M3 screws Certifications CE, RoHS www.getefento.com | +48 574 753 980 | efento@efento.pl ...

This is the mode of the reduced power consumption. The sensor takes measurements with a period set by the user and saves them in its memory. Users can read the measurements and change sensor’s settings using mobile devices with Efento mobile application installed. Device does not send / receive any data over NB-IoT network. -

31-123 Kraków LEDs NB-IoT sensor is equipped with two LEDs: green and red. If the device is on and works properly (device is in the Power Saving Mode), both LEDs are turned off all the time. Flashing of the diodes indicates the current status of the device or the action being performed by it. -

3. Green LED should quickly blink for a few seconds (first transmission over NB-IoT network) From now on, the device operates, takes measurements and saves them in its memory. www.getefento.com | +48 574 753 980 | efento@efento.pl ... -
Page 8: Configuration
Ul.Krupnicza 14/5 31-123 Kraków Configuration Network configuration The initial configuration of Efento NB-IoT sensors is done with E fento Logger mobile application for Android devices that can be downloaded from Google Play. The application allows you to configure all parameters of the sensor and read the measurements from the sensor's memory. - Page 9 If the device has not registered on the network automatically, you need to manually select the carrier. Connect to the sensor with Efento Logger, go to the “Settings” menu and select “Network settings” -> “PLMN code”. PLMN is an unique operator identifier. You should get the information about the PLMN code of your operator either from the operator or you can check it ...

Page 10: Efento Cloud
If for any reasons the device is not able to fetch the time from the network, it will try to connect to the Efento Cloud platform and get time from the server. If the connection with the server is also not possible (e.g. device communicates with a third party server, or APN is configured incorrectly), it is also possible to set the sensor’s time... -

4. Configure alert rules, which will send you SMS / email notification, if the values measured by the sensor are out of the safe range or if the sensor data do not reach the platform. On Efento Cloud go to the “Rules” tab, set up the rule and save the changes. -
Page 12: Configuration With A Custom Server
In order to set a sensor to send the data to a custom server: 1. Connect to the sensor with Efento Logger, tap on the three dots in the upper right corner -> “Network settings” -> “Server”... - Page 13 (N+1, N+2, N+3). In order to set the threshold values: 1. Connect to the sensor with Efento Logger, tap on the three dots in the upper right corner -> “Settings” -> “Device settings” -> “Alarm thresholds” 2. Set the threshold values and types for each slot. If you want to, you can set the threshold for one...
- Page 14 Ul.Krupnicza 14/5 31-123 Kraków If the sensor works with Efento Cloud, the platform informs the user, when the new data from the device is expected. Additionally, it is possible to configure how often the message sent by the sensor requires confirmation of receipt by the server (ACK).
- Page 15 Transfer limit Efento NB-IoT sensor allows you to limit the number of transmissions in a given period of time. For instance, you can set the device to be able to send the data maximum 5 times in a 30 minutes window.
- Page 16 “Settings” -> “Device settings” -> “Turn encryption off” If the encryption has been turned on, once you try to connect to the sensor with Efento Logger, you will be asked to key in the encryption key. Once you add it, the application will store the encryption key and you will be able to access the sensor without adding it again.

If for any reasons the device is not able to fetch the time from the network, it will try to connect to the Efento Cloud platform and get time from the server. If the connection with Efento Cloud is also not possible (e.g. device communicates with a third party server, or APN is configured incorrectly), it is also possible to set the sensor’s time using... -
Page 18: Battery Status
/ self check. Battery status Efento sensors will inform you about the low battery level both on Efento Cloud platform and in Efento Logger mobile application. Once a “low battery” status shows up, you will have 2-3 months to replace the battery. -

● Ping status - information if the sensor is able to reach Efento Cloud platform. Ping status allows you to verify the correct configuration of the APN - if the device is connected to the network, but does not communicate with the platform, it is most likely caused by a wrong APN configuration ●... -

APN configuration. Set APN with Efento Logger as described in Step 4. ● If the device is able to fetch time from the network - Efento sensors need to fetch the time from the NB-IoT network in order to synchronize internal time with the network time. If this feature is not available, you can set the time manually with Efento Logger by using the “Change device... -
Page 21: Power Saving Features
Data transmission in the NB-IoT network is encrypted and therefore safe. The data security problem appears at the stage of data transfer via the Internet - between the NB-IoT network and Efento Cloud / user server. NB-IoT is based on the UDP protocol, which is supposed to be lightweight. Adding security features to this protocol (e.g. - Page 22 The battery life of a device depends on many factors and it is not easy to build a model that will precisely determine this time. Efento NB-IoT sensors battery life time is up to 10 years or 130,000 transmissions. The main factors affecting battery life are: ●...
- Page 23 ● complex physics of Li-ion batteries (in the model a simplified calculation is used). Due to physical processes which happen in the battery, maximum battery life time is 11 years. After that time, the battery will discharge, even if it is not used www.getefento.com | +48 574 753 980 | efento@efento.pl ...
