Its not a smart hometrainer but I read about things that might make it work like power meters/cadence sensor.
But on my hometrainer my wheels are not accessible, is there something I can buy that is compatible with my hometrainer to be able to get zwift to work?
Generally the best way to get a wheel off trainer that isn’t also a smart trainer onto Zwift is through the use of a Power Meter. Most people find pedal based power meters to be the easiest to use since you just remove your current pedals and install the power pedals then they should pair up to Zwift and you’ll be all set. If you’re not too keen on having to wear clip in shoes then crank or sprocket based power meters may be more suitable but they do require a bit more work to install.
