SMS-GW3 LTE is a central gateway that allows HWg devices, SensDesk portals, and third-party software/hardware to send text messages (SMS) and make voice calls alerts.
Its main use is when customers have multiple HWg devices for remote monitoring. They can all 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.
SensDesk portals can also use SMS-GW3 LTE for alerting, as long as the gateway is accessible to the portal (either through a VPN or a public IP address).
For third-party users, the SMS-GW can be handy for alerting through the SNMP interface.
- Connectivity: Ethernet (10/100 Mbit/s), LTE
- LTE antenna: External 3m cable, SMA
- Internal memory for outgoing SMS queue: 100 messages
- SMS/Calls GW for all HWg devices (RME)
- SMS/Calls GW for any SNMP software
- SMS/Calls GW for any NAGIOS (plugin by NETWAYS)
- Open API: SNMP, XML, netGSM (http, SOAP)
- Supports the "SMS + Ring" function for combined SMS and ring notifications.
- Mechanical: 76 x 93 x 28 mm, wall-mountable, fits on a DIN rail
Sending SMS alerts from HWg devices over LAN
- Poseidon2 4002 sends an alarm message about a sensor value to Mr. Blue's phone number.
- Using the Box-2-Box mode, it connects directly to the SMS-GW3 LTE (no software is needed).
- SMS-GW3 LTE contains a SIM card and sends cell message alerts on behalf of all devices in the network.
- Message recipients' phone numbers (Mr. Blue, Mr. Green, ...) are configured in the sending device.
- Together with the text message, it is also possible to Voice call the recipient and let the phone ring for a short time (configured in the sending device).
Sending SMS alerts from Portal or HWg devices 
- Any Portal (based on SensDesk Technology) can use SMS-GW for sending alerts.
- All HWg devices can send SMS alerts directly (to the SMS-GW) or via the Portal.
Via Portal is there benefit of central alerts management & possibility of Device Invalid Alert (device is inaccessible or fails)
- Recipients' phone numbers (Mr. Purple, Mr. Green) are configured in the sender (In the Portal or in the Device).
One GW can be alerting to several telephone numbers.
3rd party usage of SMS-GW
- Using netGSM (SOAP - HTTP POST)
- Using HTTP GET
- Using the SNMP Write function

Nagios SMS alerts
Nagios NMS monitors other devices using SNMP. - In the Nagios system, a plugin enables SMS alerts over SMS-GW3 LTE gateway.
- The plugin configuration includes the phone numbers of text message alert recipients.
- The NAGIOS plugin was created in cooperation with Netways (MonitoringExchange: notify-poseidon-sms.pl).
