HW group STE2 PLUS SMS-GW

• To STE2 PLUS can connect up to 15 external sensors to 2x RJ11 ports.
  LAN & WiFi monitoring device STE2 PLUS is a professional product with HTTPS custom certificates, SNMPv3, SNMP Traps and IPv6.
• The SMS-GW3 LTE is a central gateway that allows to HWg devices or SensDesk portals to send text messages (SMS) and make voice calls alerts.

This bundle package with 2 devices is a cost effective way to build a remote monitoring installation with SMS / Call alerts included even without the Portal. SMS GW device can be used by other HWg devices as central point to transmit SMS & Calls even from other HWg devices.

• Remote technical rooms monitoring
• SNMP / Email alerting with GW for SMS / Calls included.
• Remote monitoring of refrigerator or freezer (alert when refrigerator fails, logging of operating and storage conditions)
• Single SMS gateway for the entire network (other HWg devices) with an easy-to-use web-based configuration

STE2 PLUS sensors

Up to 15 external temperature sensor values can be connected to STE2 PLUS. Sensors can be daisy-chained from RJ11 port. One physical sensor can measure several values (°C + %RH = 2 sensor values). The maximum limit is 15 sensor values in total.
