▶Designed for Flexible Zigbee Deployments
SEG-X3 combines Zigbee 3.0, WiFi, BLE pairing, local automation, and open API integration in a compact gateway for smart home, HVAC, energy management, and light commercial IoT applications.
▶Zigbee WiFi Gateway vs Ethernet Gateway
SEG-X3 is designed for flexible Wi-Fi deployments, while SEG-X5 provides Ethernet connectivity and higher Zigbee device capacity for larger IoT projects.
| Feature | SEG-X3 | SEG-X5 |
|---|---|---|
| Primary Network | Wi-Fi 2.4GHz | Ethernet 10/100 Mbps |
| Zigbee | Zigbee 3.0 | Zigbee 3.0 |
| BLE | BLE 4.2 | BLE 4.2 Optional |
| Zigbee Capacity | Up to 50 EPs* | Up to 200 EPs* |
| Local Automation | Yes | Yes |
| Open API | Server API + Gateway API | Server API + Gateway API |
| Best Fit | Flexible Wi-Fi deployments | Larger Ethernet-based deployments |
*Maximum Zigbee capacity requires repeaters. Without repeaters, both gateways support up to 32 end devices.
▶ System Integration
SEG-X3 provides open Server API and Gateway API for third-party integration, supporting HTTP Server API, MQTT Gateway API, and flexible integration with cloud platforms, mobile applications, and IoT systems.
▶Application
The SEG-X3 Zigbee WiFi gateway is designed for applications including:
Home Energy Management Systems (HEMS) – connecting energy meters, sensors, and control devices for energy monitoring and automation
Smart Home & Light Commercial Automation – connecting Zigbee sensors, thermostats, and controllers through a Wi-Fi network
HVAC Control Systems – integrating Zigbee thermostats and sensors for connected HVAC applications
Smart Building Applications – supporting Zigbee device connectivity for smaller building automation projects
IoT Platforms & System Integration – enabling integration with third-party cloud platforms, applications, and private systems through open APIs
