Support Context
Why this answer matters
This FAQ is sourced directly from our support database. It helps teams deploy GPSController faster, reduce onboarding friction, and understand platform compatibility for real-world fleet operations.
Answer summary
Reefer diagnostics only report system function, not actual cargo temperature. A working cooling unit can still fail to maintain proper conditions if airflow is blocked or the space is overpacked, leading to undetected spoilage.Related FAQs:...
