I'm setting up 130 FMB920s with Traccar, but plan to use the FMB920's in build SMS function to send an SMS when power is disconnected. I have been able to make this work successfully by setting a low value of 200 for external voltage.
Is there a way to have SMS messages include a custom string as well as the alert message so that the device is more easily identified, or must we just save 130 phone numbers in our phones?
In short, I would like the message to say what vehicle has had its tracker disconnected.
