Perseus Energy 242 is a LAN solution in metal case 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.
Perseus Energy 242 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.
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 242 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.

Perseus Energy 242 is a LAN device in metal case 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 4 1W-UNI (RJ11) ports, 2 DI (Digital Inputs) with S0 pulse counters, RS-485 (Modbus/RTU), one WLD (Water Leak Detection) zone input, an M-Bus Master input, and 1 DO (Relay Outputs).
Perseus Energy 242 can only be powered from 24V. Therefore, power out terminal block provides 24V.
The combination of the RS-485 physical interface on the Perseus Energy 242, 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 242 has a WLD zone input and 1 relay output 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.
