The Efento NB-IoT open/close logger automatically registers every door, cabinet or panel movement and immediately sends a notification to the cloud when the status changes. The sensor works with a precise magnetic detector and stores all events in its internal memory. Thanks to NB-IoT connectivity, the device operates completely wirelessly, without a router or gateway, and can be easily set up via Bluetooth and a free smartphone app. Ideal for applications where access monitoring is essential, such as warehouses, cold storage rooms, technical installations, pharmaceutical storage or secured zones.
