Zwift Hub - ~33% of actual wattage

Bugs and Support

I’m getting erroneous wattage data from a Zwift Hub. Resistance was feeling high for the wattage I was seeing, so I did a test against my Favero Assioma Duo (see screenshot).

Fresh install made no difference.

- Pairing -
Power: Zwift Hub (5.2.2 FW - Hardware Rev 1)
Cadence: Zwift Hub
Resistance: Zwift Hub
Controls: Click
No HRM

Using the Favero pedals for power, I get realistic data in Zwift.

Any suggestions? I can’t use these pedals on a regular basis.

Thanks - Jeremy

Test it with the trainer paired to the Wahoo computer or some other app

If you get the same result contact support@zwift.com and maybe they replace the trainer

Don’t email more than once or they give you a support response penalty

Thanks - Same result testing the Hub against the Wahoo computer; watts well below what I should have been seeing.

I’ll email support.

Thanks - Jeremy
