Efento NB-IoT Pack, two external probes€251.00 excl. VAT
What it is for
- Two fridges or units close together, with a single device
- A fridge and its freezer, each with its own probe
- A fixed price over 5 years, with history and reports on Efento Cloud
What it is not for
- Two units too far apart for 1 m probes: ask for another length
- A site with no NB-IoT coverage: check first
- Controlling or restarting your refrigeration
Installation, step by step
- Step 1
Mount the device
Screw it in place or stand it outside the fridge or cold room, somewhere with mobile network coverage.
- Step 2
Run both probes inside
Run each probe into its fridge or cold room, at product height.
- Step 3
Configure the sensor
The mobile app sets up the sensor over Bluetooth, and it then connects to Efento Cloud over the NB-IoT network.
- Step 4
Set your alerts
Create your rules on the platform, then trigger an alert to check that it arrives.
Your readings on Efento Cloud
The pack includes 5 years of software: dashboard, floor plan of your premises, unlimited alert rules, PDF and CSV reports, mobile app, and as many users as you need.

What to know before you buy
- NB-IoT coverage varies by country and operator. This is the first thing to check.
- Battery life depends on how often the device transmits.
- The SIM card and software are included for 5 years. The sensor remains yours afterwards.
This system monitors and alerts. It does not control your refrigeration or replace your system's own probe. It does not by itself deliver HACCP, EN 12830 or GDP compliance, and your food safety plan remains your responsibility. An alert needs a network, a power supply and someone to receive it, so test it when the system is installed.
Frequently asked questions
What does the price include?
The sensor, which is yours to keep, plus the SIM card and the Efento Cloud software for 5 years. Only SMS messages cost extra.
What happens after the 5 years?
The sensor remains your property. To extend the SIM card and the software, contact us before the end of the period.
Does each probe have its own thresholds?
Efento describes simultaneous measurement in two independent zones. You create your rules on the platform for each channel.
Is a calibration certificate available?
Yes, as an option: an Efento calibration certificate for one point at 5 °C, at €29 excl. VAT per certificate. Tell us in your quote request if both probes are concerned.
