HW-group STE2 R2

The HW-group STE2 R2 is a compact, high-performance IoT monitoring device for supervising critical environmental conditions in data centers, server rooms, building management, and industrial applications. With LAN and Wi-Fi connectivity, it offers flexible deployment and delivers reliable real-time data on temperature, humidity, CO₂, VOC, light, current, and voltage levels.

Open interfaces like SNMP and XML ensure smooth integration into IT or facility management systems, making it easy to extend existing infrastructures. Combined with the HWg Monitor mobile app, administrators stay fully informed at all times.

Powerful Connectivity

The STE2 R2 supports LAN and Wi-Fi connections. Power can be supplied via PoE (RJ45), minimizing cabling complexity. Real-time monitoring and data delivery are optimized for compatibility with existing network management setups.

Sensor Variety

With two RJ11 ports and Daisy-Chain support, up to five values can be measured simultaneously. Supported sensors include:

• Temperature (server rooms, data centers, production areas)
• Humidity control for sensitive environments
• CO₂ monitoring for indoor air quality
• VOC sensors for volatile organic compounds
• Light intensity monitoring
• Current sensors (4–20 mA)
• Voltage monitoring (0–230 V)

Two digital dry contact inputs are also available for door contacts or other security triggers, expanding the monitoring possibilities.

Alerts & Notifications

The STE2 R2 provides instant alerts when thresholds are exceeded:

• Email notifications natively
• SMS and voice call alerts via SMS-GW3 or LTE gateways

This guarantees rapid response in critical scenarios without depending on external services.

Portal Integration

Free HWg-Cloud integration enables centralized monitoring of up to 20 devices. For enterprise-grade requirements, SensDesk Technology adds:

• Automated PDF reporting
• Multi-user management
• API integration into third-party systems
• Flexible alarm handling with SMS and voice calls

Mobile Monitoring

The HWg Monitor app (iOS/Android) provides live access to all sensors and alarms. Widgets allow instant visibility of critical values directly on the device homescreen.
