Not listed Trainer, powerpod or Speed/Cadence sensors

Hey there,
I am new to zwift. I use a trainer that is not smart at all GHbike 3 rolls trainer. I have also a power meter called powerpod that measures the power through calculations.
My problem is that I cannot configure my power to get accurate results. If I use the powerpod, the power is one, if I use the sensors and a nonlisted trainer, the power is another. Could someone advise me what is the best configuration that I could use?
I have no problem to use only my speed and cadence sensors to calculate power, but with this type of roller, what is the best configuration I could use?
Thanks in advance
Facundo

Hi Facundo,
welcome to Zwift.
I’m no expert, but I think it would be best to use the speed and cadence sensors to calculate your power. Many others use this set up.
Keep your eyes on the forum as other Zwifters may have others suggestions.
Hope you enjoy Zwift.
“Ride On”
