CHINT SMG-ESR Smart Gateway,
is a high-performance Open Protocol Gateway that enables seamless communication between CHINT smart devices,
furthermore user-defined IoT platforms. Using Ethernet (MQTT) for upstream data transmission,
in addition to RS-485 (Modbus RTU) for downstream connectivity, it supports reliable data exchange,
moreover remote control, and energy monitoring.
With its web-based configuration, plug-and-play design,
and full compatibility with CHINT NB2 smart circuit breakers,
but the SMG-ESR delivers flexible integration and real-time monitoring for smart power systems.
