My Tireminder system works at all times.

It monitors pressure and tire temp. You can purchase the system as linked above - that provides data to a smartphone app - or go with one with a standalone display. You do not need to be on the smartphone app to get a warning alert. A separate receiver (that communicates with the transmitter mounted on your trailer) is carried in your truck. This receiver will emit a warning tone if your set thresholds for temp and pressure are exceeded. This separate receiver is what also communicates (via bluetooth) to your smartphone.
