Several good systems out there-- they do not involve dismounting the tire.
About my only recommendation is to stick with a company that is located in the U.S. and has been in business for at least a couple of years. The is as opposed to a vendor who buys some "look alike" senders and monitors, sell them at RV shows for a couple of events, has no parts inventory, no technical expertise and may be gone next year. But, I guess that advice applies to a number of things!
Since air (or Nitrogen for that matter) follow the Ideal Gas Law, I see no reason to monitor temperature in addition to PSI and the two are ABSOLUTELY/mathematically related. And, quite frankly temperature out on the valve stem in really not a very good indication of tread or sidewall temperature.

+2 for Pressure Pro. Had mine going on 7 years now with the same sensors. Twice it has warned me of a loss of tire pressure which allowed me to pull over prior to the tire blowing and causing who knows how much damage. However, I did have a blowout on my toad's r/rear with no warning and still not sure what caused the blowout.
