Compared power readings from my Assioma Duo against inride3 sensor. Assioma was way off, like almost 100W. Assioma have been through ant+ to trainerroad and inride3 via Bluetooth to Zwift. I quite trust my inride3 tbh. Can the Assiomas just break down out of the blue?
Iām guessing you did a zero offset?
I have calibrated the Assiomas in TrainerRoad and the inride in kinetic app. When Iām outside then the readings from the pedals are very close to the inride thoughā¦
Maybe try calibrating it in the app and then getting in contact with Favero. Theyāll be able to see the calibration data from the app.

Are you able to monitor the left/right balance reported by the faveros when on the trainer via a head unit.
If the balance from the DUOs is correct then I would doubt the inride sensor not the pedals. While itās possible for the pedals to break itās unlikely that both pedals would break in the same way at the same time.
Only other thing I can think to check is to make sure the crank length is set correctly for the pedals.

Yes, as above. Calibrate both and check crank length. So some one sided pedalling to check both pedals seem reasonable. I would also trust pedals over InRide to be honest.
On a separate note, just moved from 4iiii single sided crank to Assioma Duo and loving itā¦despite fact it proved what I thought that due to left right imbalance my single sided crank overestimates power by around about 30w (FTP meant from 305 to 275w overnight 
), however I knew my power was too high for the TT times I was doing (or I had worse CdA than a MTB when in TT position!).
So, very glad to have changed to double sided (however I did train very consistently and successful with single sided for many years) to have more realistic numbers and also to allow aero testing (which was near impossible with big single sided PM fluctuations and overestimates)
Hi I had this very same problem with my P1 pedals. I opened a ticket with powertap at the time and TR. Long story short, if you use BT then the power will be double. but if you use ANT+ then you will use power from both pedals. This wasnt a TR issue, but rather then way they setup BT. therefore I will use ANT+
Guys thanks for your input, I have this puzzle solved and it was a total rookie mistake on my part! I have simply ācalibratedā the Assiomas when clipped in! Obviously the pedals have to have 0 weight
and deadly immobileā¦ now discrepancy is 10W so I think completely acceptable

Bike upright, crank arms upright, nothing touching the pedals, and the right crank length input - the secrets to a trustworthy calibration for Assiomas.

simple to fix problems are the best problems to have

In theory - If you have the duos, if you have the corresponding non sensor L&Rs can you pair them separately to be used on different bikes?
No, only the left pedal can be used as a master.

Hmmā¦ interesting they sell a left non sensor pedal
Funny enough, they do. They sell both left and right no-sensor pedals. I canāt fathom why one would buy that.
But - donāt get your hopes up, you canāt split a pair of Duos to make two pairs of Unos. The right-side pedal only talks to a left-side pedal.
This said, it literally takes 2 mins to transfer the pedals between bikes. If your goal is to equip two bikes that wonāt be used at the same time, thatās the way to go. If youāre trying to equip two bikes for two people who canāt share one set of pedals, unfortunately itās going to be 2 x Unos. Which incidentally is going to cost almost exactly the same as a pair of Duos plus two no-sensor pedals.
Hi Assioma usersā¦I think my Duoās have developed a fault. Iāve had then for a couple of years now and theyāve performed pretty flawlessly. Today to left pedal was indicating erratically, with pedal power varying from 30 w to 150wā¦although I was pedalling very light. ALSO the pedal stoke was showing 100% full circular power being appliedā¦very dubious.!
Is there any way to get my Assiomas served or checkedā¦is there a contact address or email addressā¦thanks
Iād just use the quick contact form found here:
While you are waiting for a response from them Iād start by making sure nothing is in contact with the pod when pedaling and that the pod is still firmly attached to spindle with no signs of damage.
Then Iād do a couple of calibrations via the favero app. When doing calibrations via the favero app it logs data that the folks in tech support can access and analyse.
Good luck.

Does anyone know if the assioma duos can broadcast on two BLE channels? I know it does ant+ but I am trying to connect to two devices that only accept BLE connections.
I donāt think so. I was connected to Zwift via BLE yesterday and trying to connect to the pedals via the app to calibrate them and it couldnāt find them. When I dropped the connection to Zwift it then found them.

They only support 1x Bluetooth connection at a time.

Also, you should connect to them with the app and do a calibration - this sends some telemetry back to them so they can look at data from you pedals.
