Mpa and power on garmin Fenix 7

I installed MPA AND POWER on my fenix 7, I tried it during a home trainer training but it only half worked, MPA was good but the power was at 0 all the time while it was displayed on the other watch data screens.
Do you know why please?

Hi @hugoyave,

Make sure you have your trainer also paired as a Power Meter in your Garmin. Our data field will only use data coming from a Power Meter sensor (even if that’s just your smart trainer)!

Wow thank you my watch took the power from the “trainer” sensor and not from the “power” sensor
