STE2 R2

STE2 R2: Reliable Remote Monitoring for Temperature and Environmental Data

With the STE2 R2, you receive a modern and versatile monitoring system specifically developed for remote monitoring of temperature and other environmental parameters. The device is ideal for use in server rooms, data centers, warehouses, pharmacies, retail stores, wine cellars, and many other sensitive areas where continuous monitoring of environmental conditions is essential.

Remote Monitoring and Alerting at the Highest Level

The STE2 R2 enables real-time monitoring of temperature and other environmental data. As soon as a preset threshold is exceeded, you automatically receive an email notification. Optionally, you can connect the system to an external SMS gateway or a cloud portal such as HWg-cloud.com or SensDesk Technology to additionally receive SMS or voice alarms. This way, you are always informed even on the go and can react immediately in an emergency.

Flexible Sensor Integration and Daisy-Chain Function

The STE2 R2 features two RJ11 ports, to which up to five sensor values can be connected. This is made possible by the simple daisy-chain function, allowing several sensors to be connected together. For example, a single sensor can measure both temperature and humidity.

The package already includes a robust, 3-meter outdoor temperature sensor with IP67 protection class as well as an international power supply (EU, UK, US).

Thanks to support for a wide range of sensors – including temperature, humidity, CO2, VOC, light, current, and voltage sensors – the STE2 R2 is extremely flexible in use.

Easy Installation and Intuitive Operation

Installing the STE2 R2 is extremely simple. All you need is a standard browser, as the device has an integrated web server. Configuration is straightforward via an intuitive user interface. Thanks to HTTPS support and Open API (SNMP, XML), the system can be seamlessly integrated into existing monitoring solutions.

The HWg Monitor mobile app allows convenient monitoring of all sensor values on your smartphone or tablet – whether you are on-site or remote.

Reliable Alerting and Notification

The STE2 R2 offers various alerting options. In addition to email notifications, you can also set up SMS and voice alarms if an external SMS gateway or cloud portal is used. Alerts are sent directly from the device or via the portal, ensuring particularly high reliability. For long-term stable alerting, it is recommended to use the portal (e.g., HWg-cloud.com), as public SMTP servers like Gmail or Yahoo often change security requirements and alarms may fail.

Mobile Monitoring and Portal Integration

With the HWg Monitor mobile app, you can conveniently monitor all sensor values on your smartphone or tablet. The app supports both direct connection with LAN devices and use via the portal. This gives you access to your readings anytime and anywhere.

The HWg-cloud.com portal offers numerous advanced functions, including central alarm management, visualization of sensor values in graphs, and the ability to control remote relays. For more demanding requirements, paid portals such as SensDesk Technology are available, offering additional features like multi-user accounts, PDF reports, and advanced alerting.

Areas of Application and Industrial Use

The STE2 R2 is perfectly suited for industrial use. In hotels, vacation homes, pharmacies, retail stores, warehouses, and wine cellars, precise monitoring of environmental parameters is essential. Especially in healthcare, the food industry, and logistics, continuous monitoring of temperature and humidity is of great importance. The STE2 R2 offers a reliable and scalable solution that can be flexibly adapted to individual requirements.

Compatible Sensors and Detectors

The STE2 R2 is compatible with a wide variety of sensors and detectors. In addition to the supplied temperature sensor, you can also connect temperature/humidity sensors, CO2 and VOC sensors, light sensors, current and voltage sensors, as well as 4-20mA sensors for industrial probes. Furthermore, the device also supports special detectors such as water leak detectors, airflow detectors, door contacts, motion detectors, gas leak detectors, voltage detectors, and vibration sensors. In total, up to five external RJ11 sensors and two digital inputs (DI) for dry contacts can be connected.

Industrial Applications

The STE2 R2 is used in numerous industrial application areas. In pharmaceuticals and medicine, it is used to monitor sensitive areas; in warehouses and storage rooms, it ensures control of environmental conditions; in hotels and vacation homes, it monitors air conditioning and heating; in retail and wine shops, it ensures optimal storage of goods. In the field of data center monitoring, the STE2 R2 is also a proven solution for early detection of overheating or failures.

Device Setup and Configuration

Setting up the STE2 R2 is extremely simple. Simply connect the device to your network (LAN or WiFi) and start configuration via the integrated web server. The user interface is intuitive and supports HTTPS for secure data transmission. External sensors and detectors can be easily connected and configured. Alarm definitions are also made via the web interface – you can specify at which values a notification should be sent and by which method (email, SMS, voice call) you wish to be informed.

Alerting and Display of Sensor Values

As soon as the measured values (temperature, humidity, voltage, etc.) exceed the specified thresholds, the STE2 R2 sends an email notification. Alerts can be sent directly from the device or via the portal. For long-term stable alerting, it is recommended to use the portal (e.g., HWg-cloud.com), as public SMTP servers like Gmail or Yahoo often change security requirements and alarms may fail.

Alerting via External SMS Gateway

The STE2 R2 can be connected to an external SMS gateway (e.g., SMS-GW3 or SMS-GW3 LTE) to receive SMS or voice alarms. One gateway can forward alarms from multiple devices in the network and requires no additional software or portal. This makes the system especially flexible and reliable.

Display Sensor Values – Mobile or Desktop

With the HWg Monitor mobile app, you can conveniently monitor all sensor values on your smartphone or tablet. The app supports both direct connection with LAN devices and use via the portal. This gives you access to your readings anytime and anywhere. Widgets enable quick display of preferred sensors directly on the home screen.

Free Portal Service: HWg-cloud.com

The HWg-cloud.com portal is a free service that supports up to 20 devices per user account. Here you can have email alerts sent directly from the portal, receive device status alerts (connection loss), set up simple alarm escalation, visualize sensor values in graphs, control remote relays, and manage a central alarm overview.

Paid Portal Service (Portal Providers)

For more demanding requirements, paid portals such as SensDesk Technology are available. These offer additional features like multi-user accounts, PDF reports, advanced alerting (email, SMS, voice call), multiple graphs with multi-year history, and a user account API (SNMP or XML). A portal provider list helps you find the right local service provider.
