What is this (TPMS repeater)

Can anyone tell me what this is under my Geo Pro G19RD? No identification on it , red illuminated button appears to be connected to the DC circuit.

It's the repeater for the TPMS (Tire Pressure Monitoring System).

Dang. I was gonna say I love a good "What is this" thread. But this one is done before it really got started. Good call Bama. Oh, and welcome to the forums Chine. If you have any other questions, as you can see, we have a lot of experience here. Someone will be along with an answer (sometimes pretty quickly!). Again, welcome, and hope to see you down the road!

Had my tst monitor in the house today to give it a charge. Probably 100 or more feet away from camper tires. Picked up signal on all four sensors from the house and repeater was not on. Really impressed.

I mounted my repeater on the tongue jack. It is wired downstream of the battery disconnect. If I see the red light on the repeater when stored, I know I forgot to turn off the battery.
We don't boondock, so the minimal draw of the repeater while camping isn't an issue for me.
