Hello,
Thank you for your question.
Our base FMB firmware has functionality to exit sleep modes when movement is detected by movement sensor. Movement source and ignition source configuration do not control the movement status for the sleep modes. In your case if you want to use sleep modes in a boat a special functionality should be prepared for example to exit sleep mode by selected ignition source decided by engine RPM or Digital Input 1.
Please contact your sales manager for the possibility of preparing a special firmware.
Regards, Teltonika Support.
