Hi, I use the Whoop HR sensor on my Wahoo Bold. That is nice, because I wear my Whoop 24/7 and I don’t have to use a second HR sensor.
Unforturately, my Wahoo Rival does not connect to my Whoop sensor. I have found that when I swim, the HR sensor on the Rival is unreliable, but the HR sensor on the Whoop is reliable.
So please add the Whoop HR sensor to the Rival.
