   tagline: Device connectivity, data collection, operations management, and intelligent analytics for industrial IoT. 28 multi-protocol drivers bring data up from heterogeneous devices; Spring AI lets large language models read that data and drive commands back to devices, closing the sense–decide–act–feedback loop. Distributed, multi-tenant, fully open source.
