What It Does
PMX ingests fitness sensor data over ANT+ and Bluetooth Low Energy — heart rate, power, speed and cadence, running dynamics, and treadmill/FTMS control — on embedded Linux, and exports curated, provenance-tagged records rather than a single opaque number per metric.
Why It Exists
Read the Motivation essay for the physics/transduction reasoning behind PMX's core idea: letting you choose which sensor's data becomes canonical in your records, instead of a platform silently picking or blending one for you.
