STE2 r2 – More than just a software facelift

STE2 is a simple device that monitors temperature and humidity using external sensors, supports SNMP, and connects to the Internet over Ethernet or WiFi. When a sensor value exceeds the specified safe range or digital input is activated, the device immediately alerts you by e-mail, via the online SensDesk or with a text message sent through a HWg-SMS-GW3 gateway (sold separately).

What’s new

• 5 sensor values, 1-Wire UNI support
• STE2 r2 is now compatible with all RJ11 sensors from HWg portfolio:

Modern design

STE2 r2 brings a fresh web interface design with a modern look and feel. The interface features a softer font, shading, modern buttons, and other additions.

HTTPs support

With increasing security requirements, the HTTPS protocol is now the standard in embedded (IoT) applications, too. So, besides the HW group flagship, the Poseidon2, it is now also supported by the low-end STE2 R2.

The web interface includes the new Security tab, where you can upload your own HTTPs certificate, or generate a self-signed certificate directly in the device. The public and private portions of the certificate are uploaded separately. It is also possible to upload the certificate of an intermediate certification authority. The port where the device listens for incoming connections is configurable, as it is the case for HTTP, at the General Setup tab.

Alarm targets

Where the original STE2 or other HW group devices only allow alarm alerts to be activated or deactivated for each sensor, STE2 r2 adds the ability to independently define the target recipients for each alert.

The targets are now defined at the new Alarms tab, rather than at the SMS or E-mail tabs. The targets are then assigned to sensors and inputs. So, instead of just enabling/disabling SMS and e-mail alerts, a set of targets can be assigned for each sensor or input.

STE2 r2 allows to define 2 targets, each consisting of up to 2 phone numbers and 2 e-mail addresses. Each target can have a user-defined name.

Safe Range synchronization between the device and the portal

Is your Safe Range or hysteresis misconfigured? Getting too many text messages or e-mails by mistake? No problem – STE2 r2 brings another feature: Safe Range synchronization between the device and the portal. If your device is connected to SensDesk, Safe Range values can be modified either at the device or at the portal, and with the next Push, the Min, Max and Hysteresis values are also changed at the other side. Soon, this will also include Delay and delta AutoPush.

STE2 r2 is the first smart Ethernet device by HW group with this capability (SD Devices can only be configured at the portal). However, it will still be possible to have different Safe Ranges at the device and in the portal, if preferred. SensDesk will also offer alternative ranges of allowed values, called the Notice Range.
