Why it wins

It delivers robust alarms (e-mail, SMS, SNMP Trap, Ring), a >250k data logger, and secure M2M protocols (HTTPS, SNMPv3, MQTT, IPv6) for industrial, IT and smart-building deployments.

  • Scales effortlessly: 8 sensors + 4 DI with non-volatile 32-bit S0 pulse counters.
  • Actionable alerts: e-mail, SMS/Ring (via HWg-SMS-GW3) and SNMP Traps on threshold breaches.
  • Smart control: 2 local relays plus 8 VDO mapped to other Poseidon2/Damocles2 units.
  • Broad integration: 50+ SNMP/SCADA apps, HWg-PDMS, HWg-Trigger, SensDesk Web/Mobile, MQTT to cloud.
  • Secure by design: HTTPS, SNMPv3, IPv6, Modbus/TCP, Syslog for auditing.
  • Easy rollout: built-in web server, LAN connectivity, optional PoE, and reliable local logging.

Typical use cases

  • Temperature alarms and IP thermostat/hygrostat in IT & data centres.
  • HVAC/ventilation switching for racks and technical rooms.
  • Cold-room and freezer monitoring with alarm escalation.
  • Industrial I/O over Ethernet and smart-building supervision.
  • Dashboards & analytics: SensDesk (graphs up to 3 months), PDMS (Excel export), Trigger (IF-THEN rules).
