I am definitely interested in this as well. One thing I do wish I had the ability to do was graph my temperatures over time to analyze the trend data. While driving I spot check my and notice that the PSI tends to increase on the the inside dually tires faster than the outside. If that is the case, I can slightly reduce the pressure on those inside tires to maintain a consistent PSI across the rear axle.
For me, at this point I have invested in the EEZTire system, I think that is just using RF but would definitely jump ship and pick up blue tooth if the ability to track data were to gain some traction in your project.
I'm a long time IT geek and analyst, your work definitely piques my interest
