Solving my truck’s TPMS sensor problem with the help of an RTL-SDR dongle

I can capture the TPMS data from my neighbor's vehicles from inside my house, with a barely-optimized antenna. It's not that low power.

Similarly, I am almost certain my car catches the sensors in the summer tires in the garage while I have my winter tires installed.

My winter tires don't have sensors, and it takes many KMs of driving before I get the sensor failure chime.

The same process repeats every morning.

This is definitely true for me. I take my car to the track, and my spare wheel/tire combos are stacked right next to where I park the car. When I take short trips around my town with my track wheels on, the TPMS light never illuminates. But about 30 minutes into my drive to the track, it comes on. It turns off again after I park in the garage again.

The sensors should stay off at rest though (There's acceleration sensors in the that activate them above a certain rpm value)

Many sensors will transmit once an hour (or some other long interval) to let the mothership know they're still alive. Or to warn you of a flat before you've left your house.
