No. It may provide useful information, but sensor location, connection gaps and the meaning of the displayed values limit what it establishes.
What the observation tells you
An app may record targets or delayed readings rather than continuous food temperatures. A missing interval is not evidence that conditions stayed normal. The two compartments may also have separate records that must not be confused.
A useful next step
Use the manufacturer's explanation and keep the original timeline. Combine reliable observations with official food-safety guidance, and do not present the log as a blanket safety certificate for every container.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
