Overview

In many remote or mission-critical deployments, it is crucial for administrators to be notified immediately of specific events occurring on their IoT gateways, such as a system reboot, a VPN tunnel going down, or a link failure. This guide provides a step-by-step walkthrough on how to configure a Robustel router running RobustOS to automatically send an SMS notification to a designated phone number when a specific system event is triggered. This ensures you are always aware of the status of your critical infrastructure.

What You'll Need

To successfully complete this configuration, you will need the following:

Step-by-Step Configuration Guide

This process involves creating and configuring a notification group that links specific system events to an SMS alert action.

Configure and Apply SMS Notification Rule

First, you need to create a rule that defines which event will trigger an SMS and where it will be sent.

1. From the left-hand menu, go to Services -> Event.
2. Click on  the Notification tab.
3. In the Event Notification Group Settings section, click the + (Add) button to create a new notification group.
4. A pop-up window will appear. In the General Settings section, toggle the Send SMS switch to ON.
   
5. In the Phone Number field, enter the full mobile phone number that should receive the event notifications. (Note: For cross-region or international notifications, you must add the country/region code before the mobile number. To add multiple numbers, separate them with a semicolon (";"). A maximum of 256 characters is supported. )
   
6. Scroll down to the Event Selection section. For this example, toggle the switch next to System Reboot to ON. ( Note: This example uses "reboot" as a test. For a full list of supported event types, you can browse the "Event Selection" section. In a group, you can enable the switch for one or more supported events you wish to receive under this section. )
   
7. Click the Submit button at the bottom of the pop-up window.
8. Finally, click the Save & Apply button in the top-right corner of the web interface to make your new configuration active.
   

Verification & Testing

To verify that your configuration is working correctly, you need to trigger the event you selected and check if the SMS is received.

1. Trigger the Event: Since we configured the alert for a "System Reboot," the easiest way to test this is to reboot the router. Click the Reboot button in the top-right corner of the web interface.
2. Confirm Reboot: A confirmation dialog will appear. Click OK to proceed. The router will restart.
3. Check for SMS: Once the router has rebooted and reconnected to the cellular network, it will send an SMS notification to the phone number you configured. Check your mobile phone for an SMS from the router. The message content will typically indicate the event that occurred (e.g., "System Reboot").
   

Troubleshooting / FAQ

Q: I rebooted the router, but I did not receive an SMS. What should I check?

• A1: Check SIM Card Status: Navigate to Status -> Modem Status. Ensure the SIM card is detected and registered to the network. Also, verify that the SIM card has an active plan and sufficient credit to send SMS messages.
• A2: Verify Phone Number: Double-check the phone number entered in Services -> Event. Ensure it is correct and includes the necessary country/area codes.
• A3: Test Basic SMS Functionality: Use the built-in SMS testing tool to confirm the router can send SMS messages. Go to Services -> SMS -> SMS Testing. Enter your phone number and a test message, then click "Send" to see if it is received.
• A4: Check Signal Strength: Poor cellular signal strength can prevent SMS from being sent. Check the Signal Strength indicator on the Status page.

Q: Can I be notified for events other than a reboot?

• A: Yes. In the Event Selection list, you can enable notifications for many other events, such as Primary Link Down, VPN Up/Down, DI Alarm Triggered, etc. You can enable as many as you need within the same notification group.

Q: Can I send notifications to an email address at the same time?

• A: Yes. In the same Event Notification Group settings window, you can toggle Send Email to ON and configure your email settings under Services -> Email. The router will then send both an SMS and an email when the event occurs.
