Assioma Uno pedal

My Assioma Uno is showing double normal power on Zwift - and I have the power doubling turned OFF. Its working fine with my Garmin, but not with Zwift. Ideas??!!

Zwift automatically doubles your reading if it detects that you’re using the Assioma UNO - regardless of whether or not the power doubling is turned ON.

Yes but Zwift numbers should be accurate as long as Assioma Uno power doubling is off. Something else must be wrong…

Couple of questions:

I think you indicated this, but please confirm you have turned off power doubling in the Favero app settings.

Are you connecting via Ant or Bluetooth? If Bluetooth, can you try Ant and see what happens?

Not sure it will make a difference but work taking a look. Also, did it work previously and now just suddenly start doubling?

PS You might want to redact your private information from the previous post for security reasons. In a funny small world occurrence, I used to work for an architecture, urban planning and interior design firm in San Francisco called SMWM. (Doors shuttered long ago.) Your name is definitely familiar to me.

You would need an ANT dongle to connect via ANT.

Did you have your Uno’s working correctly before using Bluetooth and they just stopped working correctly now? Or is this your first time trying to set them up?

I have seen comments on Reddit indicating that if you have the Uno’s paired via Bluetooth you need to have “power halving” on in your Assioma settings when using Zwift, whereas if you use ANT, you do not.

This may help

And this

Keep in mind that ANT+ is only supported on Mac, PC, and a few Android devices, so if you are using iPhone / iPad / Apple TV then you cannot use ANT+

Hey there,

Just installed my assioma uno pedals. Calibrated and all. Riding on zwift my power was double what my neo 2t was saying. Went into the favero app and half the power setting. Normal?

Makes you wonder what percentage of Assioma users are obliviously getting double power on Zwift?

Scary. Btw, after battling with the pedal on Zwift, its now showing double power on my Garmin too. Ugh. Im just going to factory reset and see where it all goes from there…..

The Assioma Uno works the opposite way with Zwift than other devices like Garmin, Wahoo, etc. For Zwift you have to turn Power Halving to ON by going into the Favero App on your phone, pairing the pedal, and going under device settings. You’ll just have to remember to change the settings under the Favero app after pairing, depending on which device you use. It’s definitely annoying going from indoor to outdoor rides.

Edit: Based on an above post, power halving on is only necessary for zwift if pairing the assioma uno through bluetooth.

Probably the only ones that are intentionally exploiting it. You’d have to be completely oblivious to go from 150 to 300 watts with the same effort.

I wasn’t aware of that. I use bluetooth and you definitely need power halving on when using Zwift.

Except those folks, who on advice often given, purchase and install these on their spinbike or dumb-trainer bike, because they’re told the spinbikes can way over-report, or that zpower based on speed calculation is highly inaccurate.

I doubt it’s that rare. Loads of people use cheap bikes that report World Tour power and think nothing of it, because everything works so there’s nothing to think about.
