Homtecs - H21

The Homtecs H21 is an industrial grade 3G router designed for reliable internet of things and remote site communications. Built for M2M and telemetry scenarios, the H21 provides high speed HSPA plus mobile broadband connectivity with backward compatibility to older mobile data technologies. The unit is offered with features commonly required for remote installations, including dual SIM support, LAN/WAN ports, GPIO and console access, magnetic cellular and Wi‑Fi antennas, and DIN‑rail mounting for integration into electrical enclosures.

As a Plaspy compatible device, the H21 can serve as a resilient IP transport for telemetry, CCTV, and fleet related data sent to Plaspy for monitoring and reporting. Its stay alive and automatic reconnect features, paired with dual SIM network fallback and dynamic DNS support, make the H21 a practical option where continuous remote connectivity matters. When deployed with Plaspy, the H21 helps maintain site visibility, reliable data delivery, and operational oversight across distributed assets.
