Ensure you are on the latest version of firmware to use this feature.
Digital Matter devices have the capability to accumulate run hours and odometer readings. In order to use this feature, it must first be enabled on OEM. The following settings are available:
Log Device Odometer and Run Hour Meter Readings
If this setting is enabled, the device will include the current odometer and run hour estimates in the end of trip device log.
Log Trip Distances and Lengths
If this setting is enabled, the device will include the distance travelled and time elapsed during the trip in the end of trip device log.
Always Log Device Odometer and Run Hour Meter Readings/ Always Log Trip Distances and Lengths
If these settings are enabled, the device will include these readings in it's payload with every data point during a trip.
How are these Readings Calculated?
The odometer values are not read from the vehicle, instead they must initially be set by either an async message or an SMS. The device then uses second by second GPS positions and speeds to estimate the distance travelled and increment the odometer reading, allowing for an approximation of the vehicle's on-board odometer.
If movement trips are used as an ignition source then all detected movement is added to the odometer. To prevent the odometer from incrementing during transport (e.g. Towing), the movement digital input mapping can be changed from ignition. An alternative method for starting an ignition based trip should be enabled in this case, such as run detect or wired ignition based trips.
The device run hours value can be set using either an async message or SMS. This value is then incremented during ignition based trips.
Setting the Odometer Via SMS
The following SMS Command can be used (All SMS Commands)
The Digital Matter SMS App provides an alternative to using a mobile phone, and facilitates setting the ODO for many devices in bulk.
The commands are:
E.g. #*,ODO,60534 - To set an odometer reading of 60534 km.
E.g. #*,RHOURS,5200 To set 5200 hours of run-time
Setting the Odometer Via ASYNC Message
The device's odometer reading can be set via an asynchronous message sent from the server.
Consult the DM integration document for details.
