HW-group STE2 PLUS

The HW-group STE2 PLUS is a state-of-the-art IoT monitoring system designed for reliable supervision of critical environmental parameters. With LAN, Wi-Fi, and Power over Ethernet (PoE) support, it integrates seamlessly into existing infrastructures and processes up to 15 sensor readings simultaneously. This makes it an ideal solution for data centers, building technology, industry, and logistics.

Thanks to open standards like SNMP v3, XML API, and HTTPS, the STE2 PLUS integrates effortlessly into professional IT monitoring and facility systems. Supporting temperature, humidity, CO₂, VOC, light, current, voltage, and other environmental data, it provides accurate real-time values with advanced security.
