I have the older version of the Tacx flow ergtrainer before it became the smart version (its yellow and white). Is this compatible with Zwift. I used zwift today but it wasn’t picking up the correct wattage it was 60W lower than what the tacx display was reading. I have a garmin speed and cadence sensor along with the garmin ant dongle to connect to my PC. I had calibrated my Tacx trainer before starting.
Is there anyway to make this work or do I need another trainer ?
