Perseus Energy 285 is a DIN rail LAN and LTE solution for remote energy monitoring and control applications with M-Bus Master. Connect external physical sensors (°C, %RH, A, V, …), Detectors (relay / dry contact) or WLD (Water Leak Detection) sensing cable. 3rd party meters (sensors) can also be connected via LAN or Modbus/RTU. LTE backup connectivity allows the device to stay operational in case of an Ethernet outage.
Perseus Energy 285 combines data from external physical sensors / detectors / meters with data from other HWg devices connected via LAN. Local conditions, Lua scripting, calendar or periodic scheduler help to analyze the measured data.
SMS, Call, Email or SNMP Trap alert can be sent from the Perseus device. Measured values are available via Open API (XML, Modbus/TCP, MQTT).
Perseus Energy 285 can be connected to the Portal (SensDesk Technology). Together with the Portal it is a powerful solution for professional applications.
A unique feature of all Perseus products is the Meters API. That means that Perseus can read over LAN sensor values from other devices (e.g. STE2 R2) and use this data for analysis or alerting.
The Perseus Energy 285 unit has a built-in LTE modem that serves as an SMS gateway for Perseus itself as well as other connected HW group devices, and also provides back up connectivity to the Portal.

Perseus Energy 285 is DIN rail mount device for environmental monitoring of a site of any size and complexity. Up to 100 external meters (and sensors) with 1000 values (variables) can be connected.
Within one DIN rail unit there are 6 1W-UNI (RJ11) ports, 4 DI (Digital Inputs) with S0 pulse counters, RS-485 (Modbus/RTU), one WLD (Water Leak Detection) zone input, an M-Bus Master input, and 2 DO (Relay Outputs).
Perseus Energy 285 can only be powered from 230V.
The combination of the RS-485 physical interface on the Perseus Energy 285, M-Bus Master and Modbus-RTU Meters API allows data to be read from third party electricity/gas/water meters, UPS or air conditioning products.
Perseus Energy 285 has a WLD zone input and 2 relay outputs that can be controlled via the device’s interface or according to the value of a connected sensor or detector, for example to control air conditioning, ventilation, automatic doors, etc.
Alerting options
Typical applications include remote infrastructure monitoring and alerting. From simple high temperature alerts to advanced alerts (2 out of 5 sensors exceeded limit or are inaccessible).
Mobile App can be used to display the status of all connected meters via LAN directly or via SensDesk.com Portal.
Internal LTE modem can be used to inform the Portal in case of power failure (email / SMS alerting from the Portal, including device and sensor invalid states), or to serve as the SMS/Call alerting gateway for all HWg devices in the local network.
Standalone monitoring
- Email alert can be sent from the device (requires SMTP server)
- SMS/Call alert can be sent from the device using LTE modem
