I think the idea of looking at L/R balance is to see if one pedal has gone bad. It’s unlikely both will have gone bad at the same time. If one goes bad, then the L/R balance will be way different.

They have fixed the rider position metric!
My Favero pedals have been displaying wonky standing/sitting times for around a year but the latest firmware version 6.12 fixes it.
The person writing the change log must be joking because it was absolute garbage before

This is the kind of thing I’ve had for the last year ish.
I didnt stand up once during this workout - pinky promise.
Issue seems to have gone away with new firmware.
What you say about it being a Garmin issue rings true though because the start of the issue didn’t coincide with a previous favero firmware update as far as I am aware.
Just raised a ticket with Favero as the right side pedal of my Duo has developed some fault - worked fine one day and then the next the lights were permanently on (but flickering weakly) and it wouldn’t connect to the app (the left pedal connected fine and showed about 50% battery). I did manage to get the right pedal to connect after being on the charger for a couple of hours but the light issue continued and the next day it was lifeless once again.
I like the Assiomas because when they are working they are trouble free, consistent, and according to reviews accurate - all at reasonable cost. But this latest fault is very disappointing for me as this is the 4th pair (counting spindles at least) I have had since buying my first pair early in 2018.
The first pair were replaced under warranty when the power numbers spontaneously went crazy. The second pair showed the same problem just out of warranty (1yr back then I believe) but Favero sympathised with my “unluck” and sold me some spindles at reduced price to fit to my pedal bodies which were still in good condition. They lasted until just past the warranty (2yrs by then I think) when one pedal stopped recording. Favero couldn’t resolve the problem so I bought a new pair at retail - and now I have a problem with those. I believe am still under warranty so hopefully Favero will sort me out.
My “unluck” continues 
Got these on sale because I’d picked up a general sense that they were a good value for money, especially if you want l/r balance. Apparently you need a proprietary app, which by the way is at best semi functional, in order to set them up. I am going to become the Unabomber.
I have to say I have never had a problem with the Favero app. I have never done much more than update firmware, calibrate (zero offset) when installing on a different bike, changing crank length and using the travel mode but it always works fine. Connects to both my assioma and mx-2 pedals with no issues.
But touch wood, had the pedals near 7 years, one replacement axle cos I tried to screw it in whilst gripping the “power pod” bulge by hand near the threads rather than the actual Allen key hole in the axle end. Just bought a new set of pedal bodies cos the original ones are getting a little chewed up, but will probably make the originals last till after winter, as there’s still chance of standing in muddy, gravelly farm gate ways on country lanes whilst have a snack stop.
L/R balance comes through in the app I use for my head unit.

Truely horrific to require a proprietary app to update firmware and change operating modes
@mtbtomo and calibration and crank length can even be done from your headunit

It’s truly horrible. Takes all of a couple minutes and then you never have to open it again. Never had any issues with it either 
. Even worse should you have any issues Favero support can remotely check out your pedals and even push firmware to them for you, how terrible.

Yep, I use both, I sometimes don’t have my head unit to hand when I am working on my bike or my phone to hand when I am about to step out the door on a ride.
Are there any other power meters that don’t require their own manufacturers app to update firmware? When pretty much every company out there whether it’s shopping, electrical devices, home entertainment, car parking, plane tickets etc want you to have their app, I can’t get that excited about having to use the Favero app for their pedals.
Especially on the occasion I needed a new axle, Favero tech support could already see the data from my calibration attempts.
I’ve lost track of who is being sarcastic and who isn’t now 
But just to confirm…
You need the app to:
- Register new pedals
- Convert pedals from UNO to DUO (and back)
- Upgrade firmware
- Change Bluetooth connection settings
- setting the crank length (only if your head unit or program does not allow it - head unit/program value is prioritised)
You do not need the app for calibration. Once you have done your initial setup you can safely delete the app.
I literally can not think of another way Favero could have done this

Further to my post above I am happy to say I have had the usual excellent customer service from Favero and I am being sent a replacement spindle (sensor) for my faulty right pedal.

FWIW: Over some years I have accumulated three different brand PMs (including Assioma) and each has its proprietary app. All work easily and reliably. Along with these I have Saris, Garmin, Polar, and SRAM AXS proprietary apps. It is a bit much but NBD for me. I’m sure in the not too distant future all interaction will be through your digital assistant, like “Hey HAL, I’m going for a ride. Make sure my cycling devices are ready to go.” Or maybe, “Open the pod bay doors please, HAL.”

I don’t want to “register” anything I own, although in certain cases I grudgingly comply when asked to do so by organizations with superior firepower. Everything else I could do perfectly well from my watch if it wasn’t for the requiremen to “activate” the pedals and click through half a dozen screen of nannying piffle. And yes, nigh-universal requirements for proprietary apps are a damning indictment of sports tech in general. This may have been the push I needed to go back to a Walmart Timex and manual logging.

I’m at an interesting crossroads. I’ve got Assioma Duo Shi with my SPD pedals fixed. I move them between my current road and gravel bikes without much hassle.
I just got a new road bike that has a SRAM with built in power meter. I do 80% road riding and it feels like a waste to not use the Assioma when i have them, but also feels like a waste to have a PM in my crank if i’m using the pedal based version for data capture.
I have two logical options:
- Sell the Assioma and put that money into upgrades for the new bike. This would leave me without a PM on the gravel rig.
- Sell the Force Cranks + PM and put that money into a replacement crank and chainring for the roadbike.
The final consideration is cleat choice… I may end up converting to SPD-SL for road riding in which case swapping pedals doesnt become as simple of an option.
As much as I like my Uno, i’ve had to replace the spindle twice, first under warranty the second not. It appears they have a shelf life.
What’s the longest a spindle has lasted?
Anyone had one longer than 3 years?
(I suppose there’s someone that uses it once a month that’s lasted but I’m thinking of a more common use case, say an average of once a week, so 50 times a year at minimum)
I bought my pedals in 2018 and had gone through 3 replacement spindles by 2020… but those have now lasted until 2024 without further issues.
I use them everyday in all weathers.

First spindle lasted a year, the replacement about 4.
Roughly 6000 m a year.

Purchased my pedals in 2019. No spindle replacements. Last year I replaced the pedal bodies and bearings. I average ~12k kms per year. They have been great
