One additional data input to wake FMM230 up

Hello.
I just bought FMM230 for my boat (around 6 meters), updated it to 03.29.00 rev 18 FW, and now configuring it for the application.
When the boat is under surveillance for theft, I have to monitor its location (if someone wants to towe it away), its main battery switch (engine cannot start without power if someone wants to drive it away) and hatches for the locker’s magnetic swithces (if someone wants to steal “stuff” in the lockers or gasoline). The swithes are chained and the circuit is closed when all hatches are closed. Actually the main battery switch is located in one of the lockers and FMM will be installed in one of them. In the “normal” state the switches present +12V to the device input.
And in addition I want to request its location from time to time using 4G network (2G will be closed soon). All this is made using SMS’es (requests and alarms).
GNSS is configured as movement source, DIN1 is mapped to ignition source and hatch relay chain to DIN2 (or could be DIN3) input

For saving battery I have to use sleep modes. 30mA is way too much for my application

I have few questions for the operation (I am new to FMM):

  1. If I use GPS sleep mode and use GNSS as a movement source, it has to wake up to get the position. Which timer configures that wake up? is it (in the Configurator version 1.1.7.72.B.3.29_R.11) the System/Sleep mode configuration there are two timers: Timeout timer and Periodic Wakeup timer. Timeout timer puts system to sleep but what does Wakeuptime do?
    In GPS sleep mode I assume all I/O are operational and I can detect battery turned on and hatches state change
    This takes me down to about 20mA

  2. I want to use even more advanced power saving. I think closest is the Online Deep Sleep (which also meets my power requirement, below 11mA). Same question naturally related to movements source as above and looks it wakes up also if ignition DIN1 goes to +12V. In Online Deep Sleep all I/O is turned off but it still monitors input configured as Ignition source (DIN1 in this case). Am I correct?
    How can I monitor hatches, namely DIN2/DIN3 if the boat is docked and battery switch is not turned on? How do I wake up the FMM?
    I’d like to get alarm as soon as possible if someone open any of the hatches, that is when DIN2/DIN3 goes from +12V to 0V. Looks DIN2/DIN3 cannot wake up the system. What are my options here? Could that be added in future firmware verions for kind of “intrusion detection” application?

Thank you for your assistance

I would like to second the request here for additional wake sources in DS or ODS. I have a mix of FMM130 and FMM230 devices used for customers, and my vehicle immobilization methods (I use latching relays that cut power to a circuit, not Normally Open starter interrupt relays) require that the tracker can be woken up either by +12v detected on DIN3 or use of an iButton. Note that 1-Wire is enabled during sleep on my devices.

Currently, neither appear to be possible and the ignition has to be turned on or the vehicle must be moved enough to trigger the movement-based wake. The issue with these is that on some vehicles, turning on the ignition while the immobilizer is active triggers ECU codes. So, I need the ability for a driver to access the vehicle and use their iButton to flip the latching relay closed, without first needing to turn the ignition on.

Hi,

Please check this wiki page: Custom Scenarios - Teltonika Telematics Wiki

And check this wiki page the sleep mode power consuption: FMM230 General description - Teltonika Telematics Wiki

You can customize any inputs and trigger DOUT in case the scenario that you have set is true.
