Between gauge pressure and TPMS always a few psi difference with TPMS being less. Old fashion and digital gauge usually within a PSI or two, with digital gauge reading to 0.1 PSI if you believe it.
Unless the TPMS detector is mounted on the wheel rim I am not sure what temperature other than surrounding air you are measuring. We use a IR gun gauge at rest stops to target tire temperature.
Read below to understand why we use a TPMS which at one time we thought was an unnecessary expense. Now it is like our American Express card in that we do not leave home with out one.

Yes I do realize one answer reflects the other.
