So are also not reliable.
Best you can get is remember the cold pressure and ambiënt temp at the moment of cold measurement, then calculate from the difference in pressure, the temperature in tire.

Some tmps systems with internal sensors, compensate the pressure back to fi 65 degr F.
Only with internal sensors this can be done, because those send pretty exact the temp in tire , to the little computer.
There are (AFAIK) no "market available TPMS systems with internal sensors available for travel trailer use.
