To configure SMS sender, 3 types of signals are mandatory. These values should be written inside the *job\_todo* field for each signal:

- **send-sms** - This signal takes value from the provided *source\_signal\_alias* field and checks if the value evaluates as true against the *trigger* field. If its true, the SMS sender will send the text from the *tag\_job\_todo* field to the specified phone numbers.
- **device-control** - This signal controls if the SMS sender is enabled or disabled. Its *tag\_job\_todo* parameter should be set to enable. It takes value from the *source\_signal\_alias* field and evaluates it against the *trigger* field. If the *trigger* is evaluated as true, the SMS sender will be enabled, otherwise it will disable the SMS sender.
- **device-status** - This signal indicates if the service is enabled or not. Its *tag\_job\_todo* parameter should be set to *enabled.*

Trigger expressions can be configured with basic comparison operators:

- Less than **&lt;**
- Greater than **&gt;**
- Less than or equal to **&lt;=**
- Greater than or equal to **&gt;=**
- Equal **==**
- Not equal **!=**
