Hey folks, I need some help.
It all started that my Wahoo didn't give any readings (0W always). So I started to disassemble.
When I inject a 1.2v signal with a function generator, the app shows some power and it seems to be working fine.
I've already replaced the photo coupler and the IR LED of the coupler is working (checked with camera) and the voltage is 1.2V on the LED.
However, when using a mirror or white plastic, there are no readings in the app.
I'm lost and need some hints.
