@McCarthyRyD I was also asking about Power Match for use with my Kickr Snap and 4iiii PM a few weeks ago.
The “Control w/ANT+ Power Meter” option in the Wahoo app is available for the Snap, but doesn’t work (it only works with direct drive Kickrs). See here for the discussion:
It seems strange that Wahoo aren’t planning on implementing Power Match in SYSTM… it’s standard in most other indoor training apps and there still seems to be enough people wanting the feature.
