What it is for

  • Several fridges or cold rooms spread around, with no wiring
  • A site with no usable network, subject to NB-IoT coverage
  • A fixed price over 5 years, with history and reports on Efento Cloud

  • A site with no NB-IoT coverage: check first

Installation, step by step

  1. Step 1

    Mount the device

    Screw it in place or stand it outside the fridge or cold room, somewhere with mobile network coverage.

  2. Step 2

    Run the probe inside

    Run the probe into the fridge or cold room, at product height.

  3. 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.

  4. 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.
