⚠ Important: This device only works with an NB-IoT SIM card and cloud subscription. These are not included and must be purchased separately. Without a SIM card and cloud, the data logger cannot be used.
The Efento NB-IoT data logger accurately measures and records temperature and humidity. Thanks to the external waterproof temperature probe, the logger can be placed outside the monitored area, while the probe is positioned inside the fridge, freezer, or room you want to monitor. This is ideal for situations where Wi-Fi coverage is limited or a reliable mobile connection is required.
The logger automatically sends data via the NB-IoT cellular network, eliminating the need for Wi-Fi or an additional gateway. Configuration is simple via the free Efento app on your smartphone (Bluetooth).
