Compatible Sensors & Detectors






SMS-GW3 LTE is LTE gateway for sending SMS messages from several HWg devices.

It's part of the bundle with STE2 PLUS because of the "Device-to-GW" mode.

Customers with HWg monitoring devices are using one SMS-GW for alerting. Several HWg devices (on the same LAN) can connect to a single SMS-GW to send alarm alerts (SMS/voice calls) to different phone numbers. No extra software is needed, and it works over the local network using Box-2-Box (Peer-to-Peer) communication.
