HW group STE2 r2

STE2 r2 can connect up to 5 sensors via 1-Wire and 1-Wire UNI and up to two detectors via digital inputs for dry contacts.

A built-in web server is used for configuring. The device can be monitored remotely over the internet using the free SensDesk portal in combination with the SensDesk Mobile application for iOS and Android. It is supplied with free HWg-PDMS software to create graphs and export data to MS Excel.

STE2 r2 is a device with SNMP support designated for measuring temperature and humidity from external sensors, with the option of connection to the internet via Ethernet or WiFi. In case the permitted range of values is exceeded, STE2 r2 sends an alarm via e-mail and has an Alarms tab, where you can define up to 3 sets of targets an assign them to individual sensors) via the SensDesk portal or via SMS using standalone HWg-SMS-GW3 gateway in the same LAN.


Applications and usage:

• Air conditioning failure
• Heating optimisation
• HVAC supervision
• Monitoring of refrigerator or freezer
• Food storage

STE2 r2: features for IoT projects

• HTTPS support
• Hardware r2
• Data transfer over Ethernet / WiFi
• Quick view to current data on SensDesk web portal
• Mobile application, desktop apps
• Sending data by e-mail, custom sw or cloud third-party applications
• Use standard TCP and SNMP protocols
• The STE2 r2 units have a dual interface Ethernet and WiFi. Data can be transmitted via the HWg-Push protocol to the SensDesk public portal or HWg-PDMS software.
• The SensDesk IoT portal provides quick previews of current values on the mobile phone as well, or it can display graphs of measured values up to 3 months back. It also includes the ability to set alarm messages via e-mail or SMS (with own HWg-SMS-GW3 gateway) in a cloud-like web page.
• IoT PDMS software allows to collect all measured data and convert it to Excel format. It can then perform its own analysis. Excel reports from PDMS can be used to document environmental values for control bodies, for example, in pharmacies and the food industry.
• Thanks to SNMP support, values from STE2 r2 can easily be accessed in other 3rd party IoT portals.
STE2 r2 is a typical representative of simple and reliable IoT solutions because it provides the ability to measure up to 5 values including two binary contacts and communicates with a reliable TCP protocol with the security of data delivery. Real-time tracking supports the use of timestamps for transmitted data.

You will have a complete overview

HWg-PDMS software is provided free-of-charge with the STE2 r2 device, allowing you to transfer the measured values to graph form and to export data to MS Excel. You can easily create comprehensible reports with graphical representations of temperature in one or a number of locations. When communicating with other devices, the STE2 r2 device uses the following communication protocols: SNMP, XML, HWg-Push.

You can connect: Up to 5 sensors (Temperature (Pt1000) Humidity CO2 Water Leak detection Barometric Pressure Current (4-20 mA) Voltage) and 2 DI inputs


Choose what you want to monitor

Are you only interested in the temperature and humidity, or do you need to know something else? Up to five different temperature and humidity sensors can be attached to the device. It also has two additional DI inputs for potential-free contact. You can also monitor door opening or movements in a particular room.

Follow everything online
You can choose whether to connect the STE2 r2 thermometer to the internet via a RJ45 Ethernet cable (100BASE-T), which also supports a PoE power supply, or by using the built-in 2.4GHz Wifi antenna (802.11 b/g/n). The device also has a built-in WEB server, so you will not need any software apart from a standard web browser. We will provide you with free access to the SensDesk.com online portal, where you can store all your data and via which the device can send you alarm messages. The security of your data is password-protected.
