Hey! Welcome to the forum!
I don't know much about the TPMS set ups, other than tire shops hate them!
The (factory) ones I've seen have been incorparated into the valve stem, making changing tires are a pain, becuase of the sensor/sending unit hanging inside the wheel.
Changing wheels, you should be able to install the sensors into the new wheels. My dad did this with his Suburban when he went from 16" to 17" wheels and taller tires. The sensors work fine for him.
None of my rigs have it, so hopefully some Jeep owners who have them can shed better light on this for ya.
