Unable to monitor 2024 Chevrolet Silverado TPMS at 315 or 433

[ksaye]

I have monitored many TPMS with rlt_433 and have been very happy with the results. So far, all have been at 315 MHz, and I have monitored 2009 - 2020 Mazda, Lincoln and GMC.

I recently purchased a 2024 Chevrolet Silverado Custom and from what I read (https://accessories.chevrolet.com/product/tire-pressure-monitor-sensor-(xl8-433-mhz)-86530815); it appears that they use 433 vs. 315. Even when switching to 315 MHz, I do not see anything even when I use a EL50448 Relearn Tool.

Before I start deeper analysis, is this a known issue? I did not see anything in the issues list.

Quickest way would be to use some SDR GUI and watch the band while triggering the TPMS. When you find the signal then record a sample with rtl_433 to analyze. You could do with only rtl_433 but it's some trial and error to record something.

Thanks for the pointer @zuckschwerdt. Unless others have already done the homework, I will start this in a few weeks and update / close the issue when complete.
