FAQ
Can weather affect my fuel theft sensor accuracy?
Yes, significant temperature swings cause fuel to expand or contract, leading to false 'refuel' or 'theft' events if the system doesn't account for thermal compensation.

What is the most common cause of a fuel sensor data mismatch?
The most frequent cause is fuel sloshing in a partially filled tank during sharp turns, braking, or on inclines, which the sensor reads as a rapid level change.

How does alert fatigue contribute to operational delays?
Alert fatigue creates human lag. When managers get bombarded with alerts for every minor stop, they start tuning them out. This means even perfectly timed, critical geofence alerts might sit unseen for an hour, completel...

Why do I get an exit alert but never got the entry alert?
This happens when a vehicle is inside the geofence zone for less time than the device's reporting interval. The vehicle enters and leaves between two location points, so the system only sees it go from 'outside' to 'outs...

Does making a geofence larger help reduce delay?
Yes, making a geofence larger helps reduce delay. A bigger geofence provides a larger geographic window that accounts for GPS drift and the time between reports, making it more likely the crossing gets caught on the next...

Can poor cellular signal really delay an alert by 10 minutes?
Yes, absolutely. When there's no cellular signal, the device stores the data and only sends it when it reconnects. The alert will have the correct timestamp for when it happened, but you won't receive notification until...

What is the most common technical cause of geofence alert delays?
The most common technical cause is the GPS device's reporting interval. If the unit only sends location data every five minutes, the server cannot generate an alert until it receives that data, creating a several-minute...

What should be the first diagnostic step when temperature alerts fail?
Start by verifying the data source: pull the raw temperature log for the suspect unit and timeline to see if the sensor was even recording data. If data exists but no alert fired, audit the alert rule's threshold, delay...

What power cycling issues can cause temperature alerts to fail?
When a trailer's auxiliary power unit (APU) or battery is disconnected for maintenance and reconnected, the gateway might boot but fail to re-establish a proper data session with the cloud platform. This leaves the syste...

How does sensor drift affect temperature monitoring accuracy?
Sensor drift occurs when probes slowly lose calibration over months, causing inaccurate readings. For example, a probe might read 2°C while the actual trailer air is at 6°C, silently breaching the safe zone without trigg...

What causes the 'delayed ping' scenario in temperature monitoring?
The 'delayed ping' scenario occurs when a sensor records a temperature spike, but the cellular gateway in the trailer fails to transmit the data packet immediately due to poor signal in rural areas or parking garages. By...

When should I upgrade from basic alerts to a full protocol system?
Upgrade when you manage multiple sites, have over 20-30 pieces of tracked equipment, or experience frequent alert fatigue or missed violations. This indicates the need for customizable alert tiers, integrated response lo...
