The STE2 is a monitoring device that supports 3 sensors, WiFi, PoE, 2 digital inputs, SNMP and more! It’s designed for temperature and humidity measurements from external sensors and the ability to connect to the Internet via standard cable or Wi-Fi. When the permitted range of values is exceeded, the device allows alarm messages to be sent by e-mail (TLS), the SensDesk portal (HWg Push). The package includes a power adaptor and temperature sensor.
