STE2 r2 can connect up to 5 Sensors (5 sensor values) via 2x RJ11 port (1-Wire & 1-Wire UNI) and up to 2 Detectors via DI (Digital Inputs) for dry contacts.
A built-in web server is used for device configuration. STE2 r2 is a device with SNMP support designated for remote monitoring Temperature, Relative Humidity, and other external sensors.
The device can be connected via Ethernet or WiFi. When the measured temperature (humidity, voltage, ..) on the external sensor(s) exceeds the defined Min-Max range (Safe Range), STE2 r2 sends an email alert ( or SMS, or Voice Call). In the device configuration, there is the Alarms tab, where you can define up to 3 sets of targets and assign them to individual sensors.
STE2 r2 is Standalone Monitoring device, which means the device can be fully configured via the web, can send emails itself (SMTP server), supports SNMP, etc. The connection of the device to the Portal (SensDesk Technology) is possible but is not enabled by default. The portal has to be manually activated as a functional extension (central device management, data history, SMS, and Voice Call alerts). The manufacturer provides limited free of charge portal service (HWg-cloud.com) and paid service (SensDesk.com), check the Portal providers for other available portals.
The STE2 r2 package includes a universal power adaptor. The device can be also powered from the PoE. One temperature sensor is also included.
It is supplied with free HWg-PDMS windows software to create graphs and export data to MS Excel.
Mobile App HWg monitor (IOs & Android) display current sensor values from devices on the LAN (WiFi) together with sensor values from the SensDesk Technology portal.

Setting the device
- Connect the STE2 r2 Thermometer to the network via a LAN or by using the built-in WiFi antenna.
- The device has a built-in WEB server, you will need only a standard web browser. HTTPS is also supported.
- Connect external sensors + detectors
- Define Alerts
- The device will alert you by email when the sensor value exceeds "Safe range" or the DI input is closed.
- Email can be delayed or sent periodically. STE2 r2 supports also TLS so the Gmail SMTP servers can be used.
- Use external SMS- GW3 for SMS alerts
SensDesk Technology Portal
- SensDesk portal offers simple configuration, central device management, and tools for remote overview of sensors
- SensDesk portal will alert you even for STE2 devices disconnected from the internet.
- SensDesk portal is able to send alerts (e-mail, SMS, Voice Calls), show graphs, create reports, store historical data, connect data via open API...
Sensor values in graphs & reports
SensDesk Technology portal shows sensor value graphs and alerts you when the STE2 device is not working or any sensor is out of defined limits. For an example of working with charts in SensDesk, see the application note.
