Thank you for the question.
You can only configure SMS to be sent when the voltage is in one of 3 intervals
In the configurator->I/O->AIN
- Set your wished priority
- High level 8000, Low Level 4000
- Operand on both
- Select your number entered IN configurator->SMS \ Call Settings->Predefined Numbers (make sure you have SMS data sending enabled too)
This way you will get SMS if voltage crosses <> mark from either side 0-4000 <> 4000-8000 <> 8000-30000
If you're using AIN, to measure fuel level it probably doesn't work as you expect.
Voltage measurements have to be calibrated to the specific fuel tank.
This is because after measuring the fuel levels the graph might look like this:
