Early warning for wheel-end heat
A bearing problem usually announces itself as heat first.
Trailer Smart gives owners and fleets a live temperature signal between walk-arounds, helping drivers stop and inspect before a hot hub turns into a damaged spindle, roadside tow, wheel-off event, or lost trip.
How it works
Simple monitoring from the trailer to the phone.
Connect the trailer monitor
The ESP32-based monitor sends readings over Bluetooth to the Trailer Smart app.
Get warned before trouble grows
High and critical thresholds help the driver decide when to pull over and inspect.

The app experience
Built for quick decisions while towing.
The dashboard focuses on the readings a driver actually needs: connection state, freshness, wheel position, and severity. Setup tools support trailer profiles, wheel counts, sensor IDs, and Fahrenheit or Celsius displays.
Dashboard
Readable wheel-by-wheel temperatures with normal, warm, high, and critical states.
Profiles
Save trailer names, wheel counts, sensor mapping, and alert levels for repeat use.
Alerts
Configure high warning and critical thresholds for your trailer and load.
Support
Give customers a clear place for app version, setup guidance, and release notes.
Who it helps
For people who cannot afford a surprise trailer failure.
RV owners
Protect family trips from avoidable shoulder stops and expensive wheel-end damage.
Horse trailers
Make earlier pull-over decisions when animals, schedules, and heat risk all matter.
Contractors
Keep utility and equipment trailers moving with fewer surprise downtime events.
Rental fleets
Add a practical monitoring layer for trailers that see different drivers and loads.
Hotshot operators
Monitor loaded trailers between stops on long runs and deadline-driven routes.
Commercial fleets
Support preventive maintenance with temperature visibility at the wheel end.
Why it matters
Walk-arounds are essential. They are also just one moment in time.
Wheel bearing heat can build from friction, lubrication loss, contamination, preload issues, or component damage.
Trailer Smart adds live visibility between inspections, helping drivers react while there is still time to stop and check the trailer.
