Who we are

We develop wireless sensors and IoT cloud platform for sensor data

Efento was founded in 2014. Since the beginning, we focus on solutions in the field of Internet of Things (IoT), Machine-to-machine communications (M2M) and Cloud computing.

As one of the few companies in the world, we offer an integrated solution for monitoring and analyzing various physical parameters, based on wireless sensors (Bluetooth Low Energy, Narrowband IoT), advanced cloud platform, and mobile applications.

Our vision

We want to make monitoring of any physical or chemical value as easy as possible

In the coming years, billions of IoT devices will be deployed around the World. Efento is one of the World’s pioneers in physical and chemical values sensors based on wireless IoT communication techniques. When designing our products, we make sure that both our hardware and software are:

Convenient to use

Our solutions are designed to make the setup and operations as easy as possible. Unlike the current hardware, our loggers are easy to install and work for a long time without any maintenance by the users. Data collection and analysis software is hosted by us, so customers do not need to worry about setting up, maintaining and updating server infrastructure.


We offer a complete solution for data collecting and analysis including sensors, transmission and cloud platform.

Cost efficient

Our solutions are designed in a way to be cost effective. Due to simple installation and no maintenance, long battery life, low transmission costs and software hosting in the cloud, the total cost of ownership of Efento products is lower comparing to traditional monitoring solutions.


We believe, that the IoT is all about data. That’s why Efento’s sensors and cloud platform allow you to integrate with any third party solution and enrich your data with the insights you may get from the wireless sensors

Over 20 sensors

We have over 20 types of wireless sensors in or product portfolio

Our wireless sensors can work up to 10 years on batteries

Short history of Efento




We already cooperate with distributors in 25 countries.


Wireless illuminance logger

Wireless illuminance logger is a lux meter, measuring the intensity of light as visible by the human eye. The precision spectral response and strong IR rejection of the device enables it to accurately meter the intensity of light as seen by the human eye regardless of light source.


NB-IoT and BLE sensors - FCC certification.

Efento NB-IoT and BLE sensors are now FCC certified and can be delivered and used in the USA.


Efento Cloud update.

The latest Efento Cloud update brought a bunch of new features including full support for 4-20 mA / 0-10 V sensors with conversion of the measurements to other physical values, information about signal quality for NB-IoT sensors and improved alert rules configuration.


4-20 mA / 0-10 V sensor interface

Efento 4-20 mA / 0-10 V sensor interface allows users to connect any type of analog sensor. Device can be equipped with up to four analog interfaces (2 x 4-20 mA and 2 x 0-10 V). Sensors can be powered either from the device’s battery or by an external power source. 


NB-IoT motion / presence sensor released

Allows to detect motion (like regular PIR sensor used in alarm systems) or room occupancy (conference rooms, office spaces, etc.). User can configure the device to detect every single movement or set the number of movements in a time period required to detect the room occupancy. NB-IoT motion / presence sensor


Efento mobile application

Efento mobile application allows users to interact with all Efento sensors
(configuration, reading the measurements) and Efento Cloud platform (access to the sensors measurements and all cloud functions through a mobile device). Application is available free of charge in Google Play.  You can display current and historical measurements from the sensors, check the alerts, change the alarm rules, generate and schedule reports and manage users. All you need to do is download a free mobile application from Google Play and log in to your Efento Cloud account. The application is also used to wirelessly configure NB-IoT sensors and Efento Gateways.


Efento limited liability company

On December 31, 2021, the company changed its legal personality, becoming a limited liability company.
The current name of the company: Efento spolka z o.o.
Other data remained unchanged.

In March 2017 Efento sensors were awarded a gold medal at the Automaticon 2017. Automaticon is Poland’s largest automation and measurement fair.



In December 2016 our Hungarian partner started selling Efento solutions. The Hungarian site is available at, and the Hungarian branch is our first offshore base. From December 2016 all our products support Hungarian.



In July 2016 we launched Efento Cloud platform for monitoring of physical parameters and management of Efento sensors.

We now offer Bluetooth – Ethernet gateway, a device that receives measurement data from Efento sensors and sends them to Efento Cloud.



Till the end of 2015 our systems are monitoring temperature in above 1000 vehicles delivering medicines and vaccines to pharmacies and in more than 3000 medical refrigerators



In September 2015 we introduced humidity and atmospheric pressure sensors. The sensors cooperate with Efento Logger and Efento Inspector mobile applications



In June 2015 we developed and launched Efento Transport application. The app has been implemented by Polska Grupa Farmaceutyczna S.A. As a part of a pilot project, the application monitored temperature in 50 vehicles, then the system has been deployed in more than 350 vehicles of the company.



Till the end of 2014, customers bought over 1000 Efento sensors. They have been used mainly for monitoring temperatures in medical refrigerators in clinics and health centers, vaccination points and pharmacies.

We introduced Efento Logger application registers temperatures in cold stores, during food production and transport, when mapping temperature in buildings and in other objects. The system also gained great popularity in viticulture, to determine SAT and GDDC parameters.



First Efento sensors and loggers were launched in June 2014. At this time we also developed the initial version of the application for monitoring temperature in medical refrigerators – Efento Inspector. The products quickly became bestsellers. The main customers are clinics, health centers, vaccination points.
Efento Inspector is a modern solution with a greater number of functions and easier operation than other systems for temperature monitoring.



Efento company was founded in March 2014. Our purpose has been the introduction to the market of new convenient and easy to use wireless temperature sensors and loggers based on the newest Bluetooth Low Energy communication technology.
