There are a lot of very good treadmills in the gyms and at the homes of a lot of users that don’t have bluetooth.
And, until now, the only way to get them into Zwift is using a Garmin watch (with awful results) or a Zwift Runn device (worst indeed!)
But now, with QZ and a raspberry, you can create a bridge from your treadmill to Zwift!
Have a look to this link: https://github.com/cagnulein/qdomyos-zwift/issues/525
An user, for example, transformed his Rebook GT50 treadmill with no bluetooth at all, in a smart treadmill! With also auto inclination on zwift!
That’s amazing!
Please, join the QZ revolution!
