Troubleshooting: "Some Asset Meters Show 0"

Overview

If Odometer or Run Hours show 0 in Asset Inspector, the cause is usually related to the meter source.

In Perspio, these meters can come from three sources:

• Device

• Perspio

• Customer (ERP)

Understanding the source is the fastest way to identify whether the value is expected, needs calibration, or depends on another system.

 

Why this happens

Odometer and Run Hours do not always behave the same way, because each source updates differently.

A meter may show 0 because:

• The device starts counting from zero

• The meter has not been calibrated

• Ignition is not wired correctly

• The vehicle manufacturer does not expose the data

• The value comes from a customer ERP and does not auto-increment

Meter sources

1) Device

The Device source comes from the telemetry device.

How it behaves

• On OBDII trackers, the value may come from the vehicle ECU, but only if the manufacturer allows that data to be collected.

• On wired devices such as G70s, FMM130s, and similar devices, the meter starts from 0.

Why it may show 0

A Device meter may show 0 because:

• The device was newly installed and started from zero

• The vehicle manufacturer does not expose ECU data

• The expected meter data is not available through the device

Important

For OBDII devices, Perspio can only display what the vehicle allows the device to read.

2) Perspio

The Perspio source is calculated by Perspio.

How it behaves

• Starts from 0

• Must be calibrated at device installation

• Run Hours only increment if ignition is wired correctly

• Perspio increments Run Hours based on Trip Start / Trip End event triggers

Why it may show 0

A Perspio meter may show 0 because:

• It was not calibrated after install

• The calibration was missed or entered incorrectly

• Ignition is not wired correctly

• Trip Start / Trip End events are not being triggered as expected

Important

If a wired device has no proper ignition input, Perspio will not increase Run Hours correctly.

---

3) Customer (ERP)

The Customer source comes from the customer’s external system, such as:

• Syrinx

• Baseplan

• Inspection platforms such as Do Forms

• SafetyCulture

• Other ERP or external systems

How it behaves

• Value is supplied by the customer system

• It does not auto-increment in Perspio

Why it may show 0

A Customer meter may show 0 because:

• The customer system is sending 0

• The external source has not been updated

• The sync has not occurred yet

• The meter is not being maintained in the external system

Important

If the source is Customer (ERP), the value must be updated in the source system, not in Perspio.

What to check

If the source is Device

Check:

• whether the asset is using an OBDII or wired device

• whether the vehicle manufacturer allows ECU meter data to be read

• whether the device was newly installed and started from zero

Expected behaviour

• OBDII: may stay at 0 if ECU data is not available

• Wired devices: may start from 0 unless another source or calibration strategy is used

---

If the source is Perspio

Check:

• whether the meter was calibrated at install

• whether the starting value was entered correctly

• whether ignition wiring is connected correctly

• whether Trip Start / Trip End events are occurring

Expected behaviour

A Perspio meter should not remain at 0 after installation if:

• calibration was completed

• ignition is wired correctly

• the asset is generating trip events

---

If the source is Customer (ERP)

Check:

• which external system owns the value

• whether that system has the correct meter reading

• whether the integration sync has run

Expected behaviour

Customer-source meters do not increase automatically in Perspio. They only change when the external source updates them.

Quick troubleshooting guide

Odometer shows 0

Possible causes:

• Device source is OBDII and ECU data is unavailable

• Device source is wired and started from 0

• Perspio source was not calibrated

• Customer source is sending 0

Run Hours shows 0

Possible causes:

• Perspio source was not calibrated

• ignition is not wired correctly

• Trip Start / Trip End events are not firing

• Device source is not receiving engine/run data

• Customer source is sending 0

---

Best practice

When installing a new device:

• Confirm which meter source will be used

• Calibrate Perspio meters immediately after installation

• Verify ignition wiring on wired devices

• Confirm whether OBDII ECU data is available

• Do not expect Customer (ERP) meters to auto-increment in Perspio
