The Thermo King integration, also called Thermo King reefer tracking or trailer telematics, connects your Thermo King account to Alvys so that trailer location and temperature data sync automatically.
Overview
The Thermo King integration, also known as Thermo King reefer tracking or trailer telematics, connects your Thermo King account to Alvys so that trailer location and temperature data sync into Alvys automatically. The integration is one-way: Thermo King sends data to Alvys. Once connected and mapped, dispatchers can view trailer positions and temperature readings directly in Alvys without switching between systems.

Trailer GPS location
Temperature readings for up to three zones: ambient, probe, supply air, and return air
Setpoint temperatures
Fuel percentage
Power status
Data refreshes on Alvys's standard polling interval, not in real time.
📋 What is not available through Thermo King: truck location tracking · driver HOS data · IFTA mileage reporting. Each trailer must be mapped individually; there is no bulk mapping option.
Troubleshooting
Trailer location or temperature not showing in Alvys
Confirm the trailer unit is powered on and has an active connection in Thermo King.
Verify the Integration ID in Alvys matches the trailer name in Thermo King exactly, including capitalization and spacing. Go to "Management > Fleets > Trailers", open the trailer record, and compare the Integration ID to the trailer name shown in Thermo King.
If neither of those conditions applies, contact Alvys support.
