I came across this today and thought tire safety monitor would be a good add-on to our TPMS system since we don't get actual tire pressure readings or other data that might be useful. Early bird price currently $99. Will retail for $119. This may be one crowd funded project that I actually pitch in for. Anyhow, just thought I would share.
