BeMini (B3-MIOT-NA) Rechargeable Device

BeMini is the newest addition to BeWhere’s asset tracker family. Discover endless tracking possibilities with our new BeMini, about 1/4 of the size of our current devices.

Rechargeable with micro-USB, the BeMini features sensors like motion, temperature and light along with Wi-Fi indoor location. Its small and lightweight design can be used in compact spaces or where a discreet tracker is a better fit. It opens up the potential use cases for tracking a broader array of assets, both smaller and those requiring indoor and outdoor location.
