This is very interesting. You are not the first one that says the setting “control w/Ant+ Power Meter” in the Wahoo app works. I have had this setting turned on for a year now and I can say with certainty it doesn’t work for me. My power is off by over 5% to 6% at times and well within 1% at other times. It’s a huge frustration for me because I don’t like using power match. I wonder if the reason it doesn’t work for me is because I use TR with a laptop. Maybe the trick is using the same phone the Wahoo app is installed on to run TR. I will have to try this.
