Catch an excursion before the load is ruined.
Most temperature excursions are discovered at delivery — or from a logger downloaded after the fact — when the whole load is already condemned. Navixy evaluates every packet against your limits and the rate of change between readings, so a failing reefer or an open door triggers an alert and escalation while you can still act.
The alarm fires only once the load is already over the line — the cargo is condemned.
The jump between readings trips an alert before the limit — the driver closes the door and the load is saved.
Find it in five minutes, not at delivery
An absolute threshold tells you the cargo is already gone. Watching how fast condition changes — and routing the alert to someone who can act — is what turns a loss into a save.
Alert on the rate of change, not just the limit
Navixy's IoT Logic compares each reading to the previous valid one. A steep rise — a door left open, a reefer that quit — trips an alert before the absolute limit is breached, while there's still time to intervene.
The same rule runs across 2,500+ device models with no firmware work — start from a downloadable flow and tune the threshold.
Every packet, evaluated
Each incoming reading is checked against your thresholds — not sampled or averaged away.
An escalation ladder
Route the first alert to the driver, then up the chain if it isn't acknowledged — every alert has an owner.
No gaps in dead zones
Devices log offline and store-and-forward on reconnect, so a cellular gap never hides an excursion.

The five-minute window is won on the floor
An excursion alert is only worth the action it triggers. Navixy routes the first warning to the person nearest the load — the driver, the dock lead, the cold-store operator — with the context to act before the band is breached, instead of a post-trip report no one can undo.
- Route the first alert to the owner nearest the load
- Escalate automatically until someone acknowledges
- Keep logging through dead zones and unhooked trailers
A frozen load slips — and is pulled back before it's lost
A −18 °C frozen shipment runs its corridor until a reefer stutter lets it drift. Watch the rate-of-change alert fire on the climb, the intervention, and the proof-of-condition record that closes the trip.
- Departure — box at −18.4 °C, well in band
- Rate-of-change alert: +1.1 °C between readings
- Excursion: −12.8 °C — driver alerted, reefer reset
- Back in band; time-out-of-range logged
- Proof-of-condition record sealed
- Peak temp
- −12.8 °C Peak temp
- Time out of range
- 11 min Time out of range
- Disposition
- Released Disposition
From packet to intervention
The detection mechanism, end to end — buildable on the hardware your lanes already run.
- 01
Evaluate every packet
Each reading off a BLE/1-Wire probe or the reefer's CAN feed is normalized and checked the moment it arrives.
- 02
Test limit and rate
IoT Logic checks both the absolute band and the delta from the last valid reading, with debounce so a single spike doesn't cry wolf.
- 03
Alert and escalate
The right owner is notified in real time and the alert climbs an escalation ladder until someone acts.
- 04
Log the proof
Time-out-of-range and the full curve are recorded for the condition report — whether the load is saved or not.
