Build cold-chain telematics on Navixy.
How TSPs, system integrators, and IoT teams assemble a cold-chain solution on Navixy: capture condition off any sensor or reefer, automate the decision with IoT Logic, and turn it into audit-ready proof with IoT Query — on the hardware your lanes already use.
Fires on the jump between readings — before the absolute limit is breached.
Five moves from sensor to proof
Each layer is buildable independently and composes into one solution — so you start with what a lane needs today and extend without re-platforming.
- 01
Capture
Read condition off BLE and 1-Wire probes, reefer CAN/J1939, serial/analog, door and fuel — across mixed and contractor fleets. Navixy normalizes 2,500+ device protocols into one model.
- 02
Automate
Express detection in IoT Logic with JEXL: absolute thresholds, rate-of-change between readings, door-plus-geofence correlation, debounce, and an escalation ladder.
- 03
Store & query
Persist to the Business Repository and compute with IoT Query — mean kinetic temperature, time-out-of-range, and full condition history on a schedule.
- 04
Integrate
Push results to your TMS, WMS, or BI over an open REST API and webhooks — or let Navixy be the system of record behind your own app.
- 05
Deliver
Ship it white-label: your brand, your domain, scheduled reports and proof-of-condition records your customers and auditors trust.
Capture condition off any device
Cold chain is a sensor problem before it is a software one. Navixy speaks the interfaces the load actually uses — and keeps logging when the network drops.
Measure the load, not just the unit
A reefer reports its own supply and return air — but the cargo sits a few degrees warmer and drifts toward the door. Capture the unit over CAN/J1939 and place BLE or 1-Wire probes in the load (front, middle, rear), and Navixy normalizes every source into one schema your logic and reports read from.
The unit reports its supply air; the load sits a few degrees warmer and rises toward the door. Place probes in the load — front, middle, rear — not just on the unit.
BLE & wireless sensors
Battery wireless temperature, humidity, and door sensors — ideal for trailers, totes, and last-mile boxes without wiring.
1-Wire multi-point probes
Chain front / middle / rear probes inside the load — because supply air is not product temperature.
Reefer CAN / J1939
Read set point, supply and return air, alarms, fuel, and run-hours straight off Thermo King and Carrier units.
Offline buffering
Devices log to memory and store-and-forward on reconnect, so dead zones and unhooked trailers leave no gaps.
One platform, five layers
The same composable stack that runs fleet and field operations, read here through a cold-chain lens. Build at any layer; the ones below it are already solved.
- L1 Ingestion — 2,500+ device protocols normalized into one schema
- L2 IoT Logic — device-agnostic rules in JEXL, no firmware work
- L3 IoT Query — MKT, time-out-of-range, and custody history on demand
- L4 / L5 — open API, webhooks, and white-label delivery
White-label apps, dashboards, scheduled reports & solution templates
Open REST API, webhooks & agent interface — push to TMS / WMS / BI

sensors in · proof out
Start from a working IoT Logic flow
Import a ready-made flow, point it at your device, and tune the thresholds. Three cold-chain starters ship as importable JSON.
Rate-of-change differential — opened in the editor
The flagship guard branches on a JEXL rule: log while the load is in range, escalate the moment condition drifts between readings — before an absolute limit is breached. Import it, point the Data Source at your device, and tune the threshold; no firmware work.
Temperature & humidity threshold
Classic absolute-limit alerting for a fixed set-point band — the place most deployments start.
Idling / power detection
Catch a reefer that stopped running or lost power — a leading indicator of an excursion to come.
Build your own
Compose nodes in the IoT Logic editor — data source, logic, attributes, webhooks — with no firmware changes.
Reason over the record with IoT Query
IoT Logic decides in the moment; IoT Query is its analytical other half — it computes the compliance math on the stored record, applies ML to clean signals and predict excursions, and answers plain-language questions, so the proof writes itself.
Ask in plain language — it answers in compliance math
Type the question a quality manager would ask. IoT Query compiles it to a query over the Business Repository — mean kinetic temperature, time-out-of-range, and excursions per lane — while a model denoises a drifting probe and forecasts the breach, before it becomes a rejected load.
“Which lanes ran above +8 °C for over 30 min last week — and is any probe drifting?”
FROM readings WHERE week = -1 GROUP BY lane
Compliance math, computed
Mean kinetic temperature, time-out-of-range, dwell, and excursion counts over any window — the numbers GDP, HACCP, and FSMA actually ask for, produced on a schedule.
ML for reasoning & signal
Denoise a drifting probe, tell a sensor fault from a real excursion, and forecast a breach from the rate of change — so alerts fire on product risk, not noise.
Conversational analytics
Ask “which lanes breached above +8 °C last week?” and get a chart and a number back — no SQL, no BI ticket, no waiting on a report build.
Decisions & proof, out
Auto-clear a clean load or flag a disputed one, then push the record to your TMS, BI, or a one-page PDF — the same evidence that settles a rejected delivery.
What integrators ask before they build
The logic you author runs on hardware built for the cold
The rules and reports are device-agnostic — but they run on real, ruggedized trackers, probes, and gateways rated for reefer interiors and trailer power. Navixy certifies 2,500+ models, so you match the sensor to the lane and trust the data it sends back.
- Reefer-rated trackers, BLE / 1-Wire probes, and solar gateways
- Capture over reefer CAN / J1939, serial, and analog inputs
- Store-and-forward through dead zones and unhooked trailers
