Qubo Digital Smart B+ With Zwift

[PetterJhon]

Hello everyone,,
I'm looking for a little help setting up my trainer to use with Zwift, I use a Garmin for day to day riding; I'm not a seasoned rider by the way, whilst using Zwift in SIM mode (ERG Off) so I'm expecting my speeds to match my Garmin and also the trainer resistance altering with gradient I'm riding on. For example, if I hit a hill in Zwift the resistance does not change but I see the speed drop on the screen.openweb.vip/whatsapp-web/ https://19216801.onl/


I did a ride only to look at the difference between speeds on my Garmin and Zwift, my Garmin was showing 15mph constant and Zwift was varying between 4mph on hills to 25mph downhills, I've looked at how to calibrate with the E-Trainer app but it looks for me to enter my Watts which I cant because I don't have a power meter.

How can I calibrate my trainer to work with Zwift if I don't have a power meter?
