More info
1) Device-to-GW
Customers with HWg monitoring devices are using one SMS-GW for alerting. Several HWg devices (LAN Thermometer / Energy monitoring) 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.
2) Portal-to-GW
Any installation of SensDesk portal can use the SMS-GW for alerting. The gateway have to be accessible from the portal (either through a VPN or a public IP address).
3) 3th party SW to GW
For third-party (non HWg products) users, the SMS-GW can be usefule gateway for alerting through several Open API.
- HTTP GET

 - 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.

Device-to-GW: Sending SMS alerts from HWg devices over LAN
Customers with HWg monitoring devices are using one SMS-GW for alerting. No additional software or service is needed, just monitonig device + SMS GW. It's working over the local network using Box-2-Box (Peer-to-Peer) communication

- Poseidon2 4002 & SMS-GW are on the same LAN
 - Telephone number of Mr. Blue is defined in the web gui of Poseidon2 4002 (same as SMS-GW IP address).
 - Poseidon2 4002 sends an alarm message about a sensor value to Mr. Blue's phone number via SMS-GW over the LAN.
 - Alerting use the Device-2-GW mode, no software or portal service is needed. It's part of RME (Remote Monitoring Ecosystem)
 
- SMS-GW3 LTE contains a SIM card and sends cell message alerts (Ring + SMS) on behalf of all devices in the network.
 - One SMS-GW device can be used by several device on the LAN, each device can alert to different recipients (Mt. Green or Blue).
 - Message recipients' phone numbers (Mr. Blue, Mr. Green, ...) are configured in the sending device.
 - Together with the text message, it is also possible to Ring (Voice call) the recipient and let the phone ring for a short time (configured in the sending device).
 
Portal-to-GW: Sending SMS alerts from the Portal
Any installation of SensDesk portal (SaaS / On-premise) can use the SMS-GW for alerting. The gateway have to be accessible from the portal (either through a VPN or a public IP address).

- Any Portal (based on SensDesk Technology) can use the SMS-GW device for sending alerts (Ring + SMS).
 - The SMS-GW have to be accessible from the Portal (same LAN / Public IP / VPN)
 - One SMS-GW (SIM card / phone number) can be alerting to several recipients (telephone numbers) from several Teams (company accounts) in the Portal.
 - All HWg devices are connected to the Portal, based on conditions defined on the Portal are send alert via the SMS-GW.
 - Alerting via Portal is more reliable due possibility of Device Invalid Alert (device is disconnected from the Portal cca 60 min)
 - Recipients' phone numbers (Mr. Purple, Mr. Green) are configured in the Portal.
