Core offering

GrandCentrix develops and sells plug-and-work IoT hardware products (Modbus Cloud Connect, Asset Tracker Solar, Asset Tracker Construction, Metering Cloud Connect) with integrated cellular connectivity via NB-IoT and LTE-M. The company also provides customized end-to-end IoT development services covering embedded hardware/software, cloud backend infrastructure and data analytics (AI), and companion mobile/web applications for enterprise clients seeking digital transformation through connected products.

Product overview

GrandCentrix operates a two-pillar strategy combining IoT product development with IoT solution services. As a product house, they develop plug-and-work IoT devices including Modbus Cloud Connect (NB-IoT/LTE-M gateway for Modbus devices), Asset Tracker Solar (solar-powered GPS tracker), Asset Tracker Construction (rugged industrial tracker), and Metering Cloud Connect (smart metering gateway). As an IoT solutions factory, they provide end-to-end development services across embedded systems (hardware/firmware), cloud backend infrastructure (device management, FOTA, data pipelines), and mobile/web applications. The product portfolio also includes sub-brand products developed in partnerships: LUXONET building automation with B.E.G., RE.GUARD 2.0 water safety with Rehau, Leica FOTOS camera companion app, and specialized platforms for industrial clients like Knorr-Bremse and Würth.
