FMB920 does not switch to deep sleep while being in underground garage

Hi Gents,

We have configured our units fmb920 to switch to deep-sleep when DIN1 (ignition is off) = 0, however, when the vehicle has no direct sight to satellite, the device stays online and drains the vehicle’s battery.

Any advise is appreciated.

Thanks

Hi,

Good day, Thank you for contacting Teltonika Telematics!

Sleep mode timeout starts counting when the device is in STOP mode.

Make sure you have selected the Movement Source to Ignition, if you want device stop mode is to be detected by Ignition On/OFF

Please use link below to configure sleep mode in your FMB920 device. You can use deep sleep mode or ultra sleep mode for lowest power consumption by the device.

Dear Ashutosh,

Thank you for your reply.

As said previously, the movement detection is ignition (DIN1) in all of our devices. Though, the device can only go to deep sleep when it obtains valid GPS coordinates and sync time. Otherwise, it remains online, trying and trying to receive a signal from the satellite.

Any hints?

Thanks,
