I did look at the Wahoo thingy, but I never managed to get to the bottom of whether it would support my ANT+ cadence and HR sensors, so didn’t risk it.
The Wahoo doesn’t support ANT+ etc. per se. It connects with your phone by Bluetooth to display what’s on your phone: speed, distance, cadence, heart rate etc..
So if your phone can connect to the sensors then they can be displayed on the Wahoo. Does that make sense?
