TPMS Tire pressure monitoring System
I just installed A TPMS System and noticed that If I leave the monitor turned on and leave my trailer, the monitor continues to report the last temperature and pressure it received when I was hooked...

Unfortunately I think most TPMS operate as you're describing. If they're maintaining radio contact they are reasonably quick to inform of issues such as low pressure, overheat etc. If they loose signal, it just reports last received signal while waiting for an update. In this situation it takes about an hour for it to report a fail. If you simply get intermittent signals, with temporary reception every thirty minutes or some other value less than an hour you'll never know you have shoddy reception. I put a repeater on my TST 507 system because of this but I still don't really know if I'm getting a reasonably consistent signal or not.
