The three options
| Technology | Pack | SIM | What to check |
|---|---|---|---|
| LTE mobile | ARES12 LTE Set | You provide it | Your operator's coverage inside the premises |
| NB-IoT | NB-2x1Wire Set, Efento packs | Included in the pack | Actual NB-IoT coverage on site, which varies by country and operator |
| LoRaWAN to a 4G gateway | LoRaWAN pack | You provide it for the gateway | Radio range between sensors and gateway, and 4G coverage at the gateway |
Before you buy
A cold room or a basement can block the signal. The device stays outside and only the probe goes into the cold area. Only a test on site can confirm reception, which is what the paid on-site trial, quoted individually, is for.
The STE2 is not suitable here because it relies on your site's network. If that network goes down, no alerts go out.
Suitable products
Mobile network
ARES12 LTE Set
The device sends its own alerts by SMS, phone call or email, without going through a portal. It comes with a 3 m probe, an antenna and a power supply, and its backup battery lasts about 24 hours in a power cut. All you need to add is a SIM card.
€587.70 excl. VATFor businesses only. Your EU VAT number is checked at checkout.
NB-IoT, SIM included
NB-2x1Wire Set
An NB-IoT device with a 3 m probe and a SIM card prepaid for 3 years. The battery lasts up to 3 years at one transmission every 10 hours. For faster alerts, run it from mains power.

Three routes, depending on the product
LTE mobile
The ARES12 LTE device uses your SIM card like a mobile phone and sends SMS messages, phone calls and emails directly.
NB-IoT
A low-data-rate mobile network designed for sensors. The reading goes straight to the platform using the supplied SIM, and a battery can last several years.
LoRaWAN
A local radio link connects the battery-powered sensors to a gateway, which then sends everything over 4G. It suits sites with several measuring points.
Frequently asked questions
Does NB-IoT work everywhere?
No. Coverage depends on the country and the operator, and cold room walls or a basement can interfere with reception. Test on site before you roll it out.
Are readings lost if there is no network?
The Efento sensor stores up to 100,000 readings and the ARES12 LTE over 250,000 records, but no alert goes out while the network is unavailable.
