SEDEMAC’s OTTO is an Automotive IoT platform. OTTO comprises a resilient internet gateway device, highly secure firmware and a sharp device management cloud. These devices come equipped with GNSS, cellular internet, and inertia sensor unit.

OTTO interacts with on-board ECUs, SEDEMAC Device Management Service (SDMS), and data server via GPRS (2G) communication module.

OTTO devices are meant for on-road & off-road mobility applications. These are highly power efficient devices which also offer immobilization feature.
