We use a sophisticated algorithm in order to counter for the the many different situations that determine when a journey starts and ends. In order to keep the highest precision when dealling with stopping in traffic or passing through a tunnel (no service area), we require multiple conditions to be met. This means that shorter stops can sometimes be missed. If you only want to know the destinations the vehicle was turned on and off you can also run the Engine On/Off report.

In order to counter for the the many different situations that can occur, we use a sophisticated algorith to determine when a journey starts and ends. In order to keep the highest precision and to deal with stopping in traffic or passing through a tunnel (no service area), we require more than just a single stopped point. This means that the last journey of the day can sometimes take a little longer to come through. Once the vehicle begins driving again or has sent through a few of its “heartbeats” you will see this last journey appear.

Are you connected your vehicle to a trickle charger?

When your TMR device is installed using the OBDII Plug and Play cable, or the ignition detection wire has not been connected, the engine on/off condition it triggered using a voltage threshold of 13.2V. The resting float voltage (engine off) of a regular car battery is generally just below 13V. When the vehicle is turned on the alternator boosts the vehicle's voltage up (above 13.2V) to charge the battery and we detect this as the engine on event (> 13.2 volts).

There are various types of trickle charges, however, generally a trickle charge will keep the battery charged by continuously boosting the voltage of the battery up. This rise in voltage then tells the tracker that the vehicle has been switched on. To view this you can visit the vehicle page on site/app and then click the row with the vehicle in question. This will open a graph showing the voltage and speed the tracker is reading.

To solve this problem, create a support ticket at https://support.trackmyride.com.au/portal/en/home letting us know that you are using a trickle charger. What we can do on our end is change over the conditions used to determine the engine on/off condition to either raise the voltage threshold or use motion instead.

If you are not using a trickle charger but the voltage is still fluctuating, please look into the wiring of the device.

If you have been been receiving engine on/off notifications while driving than the first thing you can do is look over the recent voltage and speed graph for the vehicle in question. To view this you can visit the vehicle page on our site/app and then click the row with the vehicle in question. This will open a graph showing the voltage and speed the tracker is reading. Below is a screenshot of this feed. While driving, it can be seen that the voltage fluctuates, however, only minimally. If the voltage is moving below 13V or less while driving then most probably a connecting wire has come lose or the device has not been connected to a constant power source. If you suspect this is the case, contact your installer/auto-electrician.
