SMS notifications can also be sent with the Twilio module. This does not require a cellular modem, but the Gateway must have Internet access, and a Twilio account with SMS capabilities must be created (www.twilio.com). Once created, the account must be defined in Ignition.
The Twilio module is dependent on the Alarm Notification module. You must have both modules installed to send alarms.
Once the account has been defined, a Twilio SMS notification profile must also be created.
Once your Notification profile is created, you can use it in an Alarm Pipeline.
