Does a Tacx 1981 with a Tacx Ant+ dongle(T2028) work with Zwift?
That one is not is the list of hardware that is compatible with Zwift: What You Need To Ride
I believe that Tacx would need to upgrade the firmware of the trainer for it to be compatible, but I don’t see that happening.
You can still using it as a “classic trainer” and use a speed and cadence sensor to use with Zwift.
