Problem with my Powermeter

Hello everyone,
this is my first time using Zwift and I have a question: I ride on a manual trainer with a power meter and a speed sensor. Both are connected. However, Zwift always only shows me exactly half of the watts I have used. Do you have a tip for me ahead that could be?

Powermeter: assioma duo
Speedsensor: Wahoo RPM Sensor

Thank you in advance

You shouldn’t be using both a power meter and speed sensor. Use the power meter only, that will give you more reliable figures than a speed sensor. You can optionally connect a cadence sensor too.

In the Assioma settings on your phone, make sure that “compatibility with other apps” is set to “unified channel L.”
