Hello BlueTurtle,
Thank you for the question.
Keep in mind that the device surrounded by metal might have a hard time finding GNSS/GSM connection.
Please take a look at
https://wiki.teltonika.lt/view/FMA120_SMS/GPRS_command_list
You will need to send SMS command "SMSlogin SMSpasw setparam ID value", in your case the command might be:
" setparam 1400 1"
I/O#1 property parameter (ID=1400)
I/O#1 priority (ID=1401)
I/O#1 High level (ID=1402)
I/O#1 Low level (ID=1403)
I/O#1 logic operand (ID=1404)
The parameter defines when an event is sent: 0 – on range exit, 1 – on range entrance, 2 – both,
3 – monitoring, 4 – hysteresis, 5 – on changes
