conecting trainer

i have a tack bushido T1980 witch isn’t compatible with swift so i bought the upgrade smart and it still does not work

Unfortunately, that Tacx trainer is not compatible with Zwift at this time as it uses a closed system that we do not have access to.  Zwift is currently only compatible with the T2780 Tacx Bushido Smart. Tacx has asked that all questions regarding trainer compatibility be directed to support@tacx.com as they would be best-equipped to answer.
