Cut idle waste, not the work
A refuse truck idles all day, and most reports call all of it waste. But compaction and lifting are the job. Navixy reads the PTO off the J1939 bus, so IoT Logic counts only parked idle against you, then reports the fuel you save.
Fuel intelligence that tells work from waste
A garbage truck is not a delivery van. Its idle, RPM and PTO tell a specific story, and Navixy turns that story into rules and reports instead of one generic idle number that blames every working stop.
PTO-aware idle: compaction is work, not waste
Raw idle monitoring flags every minute the engine runs, including the compaction and lift cycles that are the job. Navixy reads PTO state from J1939, so IoT Logic subtracts working idle and penalizes only parked, engine-on minutes.
Fuel & PTO straight off J1939
Fuel rate, total fuel, RPM, speed and PTO state come off the SAE J1939 CAN bus on supported trackers: one manufacturer-neutral data layer for a mixed fleet.
Smart-idle rules in IoT Logic
IoT Logic separates working idle (PTO engaged) from wasteful parked idle and alerts only on the waste. No false flags on compaction cycles.
Driver behavior, in context
Harsh events, excess parked idle and speeding roll up into a per-driver score: the fair way to coach a fleet where some idle is unavoidable.
Fuel reports that hold up
IoT Query builds fuel, idle and utilization reports by truck, route and driver, so the savings are measured, not asserted.
From the CAN bus to a fuel bill you can defend
The same pipeline for every truck: read the bus, decide with rules that understand refuse work, coach the driver, report the fuel.
- 01
Read J1939
Supported trackers pull fuel rate, RPM, speed and PTO state off the CAN bus. No per-OEM integration, one data layer for a mixed fleet.
- 02
Decide — IoT Logic
IoT Logic classifies idle by PTO state and flags harsh events and excess parked idle. Compaction idle stays uncounted, so working stops aren't penalized.
- 03
Coach the driver
Per-driver behavior scores turn the signals into a fair coaching conversation, the honest way to manage a veteran refuse crew.

Report — IoT Query
IoT Query reports fuel and idle by truck, route and driver, so a reduction target is tracked against real data, not a spreadsheet guess.
Why idle is the waste fleet's most invisible cost
Fuel is the biggest line item a hauler controls, and idle is the part that hides in plain sight, because on a refuse truck a lot of idle is real work. Measure the difference and you cut the waste without a fight over the working minutes.
Fuel and idle magnitudes are third-party figures (iMatrix, US EPA long-haul illustration) shown as context, not Navixy's own results. Refuse-truck idle varies by route and duty cycle.
Measure the fuel you're actually wasting
Bring one route's worth of trucks. We'll read the J1939 bus, split working idle from wasteful idle with IoT Logic, and show you the fuel report on your own fleet.
