I've got an RTL-SDR running rtl_433 on an RPi sitting in my living room, and I regularly see TPMS sensors from at least 6 different vehicles. The sensors identify as Renault, Schrader, Abarth 124 Spider, Schrader-EG53MA4, Citroen, and Ford.
For the Schrader ones I see enough different IDs that I think I'm seeing more than one car, so I'm probably seeing a few more than 6 different vehicles.
The antenna, which is just the little few inch thing long that came with the RTL-SDR, is about 85 feet from the street in front of my house, 60 feet from a dead end gravel road that runs by the side of my house, 113 feet and 116 feet from where my nearest two neighbors park, and 165 feet from where each of the next two nearest neighbors park.
The Citreon pressure is around 125 kPa, which is about half of what nearly everything else, so I'm curious what kind of vehicle that one is.
