Industrial edge gateways connect sensor networks and legacy equipment locally, delivering unified protocols to intranets.
Edge AI Load Inference
Pain Points & Challenges
Relying on cloud-only energy analytics incurs persistent bandwidth and GPU costs, introduces regulatory compliance risks when sensitive building data leaves premises, and risks lag during sudden electrical overload.

Success Cases
FAQ
No business interruption or wall damage required: 0.5-class split-core CTs (100A/5A) clip directly onto power cables without power outages. Indoor temperature, humidity, and occupancy sensors run on battery-powered SenseCAP wireless hardware without laying conduit, allowing retrofits during normal business hours.
Full legacy compatibility across multiple gateway models: use reComputer R1000 (3x isolated RS485 + dual GbE) for multi-meter polling, reComputer R1100 (R1125 features 1x CAN bus + RS485) for CAN-based systems, or R1124 (2x DI / 2x DO) for relay contact control. Built-in Modbus-RTU, BACnet, and OPC UA protocol translation operates under 100ms latency. Old meters integrate via clip-on CTs, while HVAC chillers connect via RS485, CAN, or dry contacts.
Fully supports on-premise air-gapped closed loops: reComputer edge computers run rule engines and load analytics inside local telecom closets, streaming over LAN MQTT or internal databases with zero cloud egress. De-identified metrics can also be selectively pushed to private clouds via HTTPS/MQTT.
The schedule depends on the number of points, protocol adaptation, and available work windows. Deployment can proceed by floor or system, with the detailed timeline determined by site conditions.
Definitely — and it is simpler there: one gateway + AC + meter delivers real-time energy monitoring and dynamic savings, no complex BMS needed. Chains in fast food, gas stations, and retail can also manage stores centrally, with headquarters viewing every store's energy on one platform.
Yes. The Seeed devices used in this solution can be customized with your own logo, enclosure, packaging and pre-loaded firmware, and existing models can be adapted to add or drop interfaces and features. See Customization Service for scope and process, or .
