SMS notifications via GSM modem

SMS notifications via GSM modem allow you to receive SMS alerts from your home automation system. This can be useful for situations where you need to be notified of critical events, even if you don't have an internet connection.

Here's an overview of how it works:

1. GSM Modem: You'll need a GSM modem, which is a device that connects to your computer or home automation hub and allows it to communicate on a cellular network. These modems are readily available online from various retailers.
2. SMS Integration: You'll need to set up an SMS integration in your home automation system. This typically involves configuring the integration with the GSM modem's COM port or IP address and providing the phone number(s) you want to receive notifications on.
3. Automation: Once the integration is set up, you can create automations that trigger SMS notifications. For example, you could create an automation that sends an SMS when your home alarm is triggered or when your washing machine finishes its cycle.

Here are some additional things to keep in mind:

• GSM Network Coverage: Ensure you have good GSM network coverage in your area, as SMS notifications won't work without it.
• 2G/3G Support: While some modems support 3G networks, many are 2G only. Check compatibility with your cellular carrier.
• SMS Charges: Sending SMS messages may incur charges depending on your cellular plan.
