• LTE modem (Global): Provides backup connectivity and acts as an SMS gateway for the device itself and other HWg devices on the network.
• 4x RJ11 ports: Supports up to two 1-Wire UNI sensors per port for measurements such as temperature, humidity (indoor/outdoor), voltage, or current (0-30A or 4-20mA).
• RS-485 (Modbus/RTU): Enables integration of third-party sensors, such as power meters or air conditioning units.
• WLD port: Supports a water leak detection cable with a total length of up to 185 meters.
• Digital inputs and outputs: Four digital inputs (DI) for dry contacts (e.g., smoke detectors, door sensors) and two digital outputs (DO) for controlling relays, such as for air conditioning or automatic doors.

Data Processing and Analysis

The Perseus Monitoring 145 offers advanced data analysis features enabled by Lua scripting. Companies can create custom logic to monitor complex conditions, such as triggering an alarm if two out of three temperature sensors exceed a critical value. Calendar and scheduling functions allow monitoring tasks to be executed at specific times, increasing flexibility in dynamic environments. Virtual sensors enable calculation of averages or other aggregated data for more precise analysis.[1][2][3]

Alarms and Notifications

The Perseus Monitoring 145 provides comprehensive alarm options that can be triggered both locally and over the network:

• Local alarms: Relay outputs (DO) can be switched based on sensor data, e.g., to activate fans or alarm sirens.
• Network-based alarms: SNMP Trap, email notifications, SMS, or calls (via the integrated LTE modem) immediately inform responsible personnel about critical events.
• Portal notifications: When connected to the SensDesk Portal, additional features such as device invalid alerts, PDF reports, and multi-year multigraphs are available.

Open API and Integration

The open API (SNMP, XML, Modbus/TCP, MQTT) allows seamless integration of collected data into existing SCADA or NMS systems. The Meters API is a highlight, enabling the Perseus Monitoring 145 to read sensor data from other devices on the LAN network. For example, the device can compare the temperature of its own 1-Wire UNI sensor with that of an external STE2 R2 thermometer or an SNMP-enabled UPS to trigger precise alarms. This data aggregation makes the Perseus Monitoring 145 ideal for complex monitoring scenarios.[1][2][3]

Security Features

Security is a central aspect of the Perseus Monitoring 145:

• Radius – IEEE 802.1X: Supports secure network authentication.
• HTTPS with client certificate: Ensures encrypted communication.
• Admin and user accounts: Allows access control for different user groups.
• IPv6 support and SNMP v3: For modern and secure network environments.

Connection with the SensDesk Portal

Integration with the SensDesk Portal significantly extends the functionality of the Perseus Monitoring 145. The portal offers:

• Graphs and multigraphs: Visualization of sensor data with historical trends.
• Virtual sensors: Calculation of averages or other aggregated data.
• Device invalid alerts: Notification in case of device connection loss, also via LTE.
• PDF reports: For audits and reporting in regulated industries.
• Multi-user accounts: For teams with different access rights.

The SensDesk Portal is available as both a SaaS solution and on-premise. For simple applications, the free HWg-cloud.com portal is available, offering basic features such as email alerts and simple graphs. Thanks to the integrated LTE modem, the connection to the portal remains stable even if the LAN connection fails.[2][3]
