I’m similarly nervous to quickly update software when first released. I did however do the firmware update last night and then immediately did a workout and all went well so far.
Yes, I think I’ll probably update the firmware. I just think I’ll need more info before I’m going to go for a ride without doing a manual zero.
When and how do the pedals perform the auto calibration?
Since updating the firmware, I have done two rides. On both rides, the power/cadence dropped for about 5 seconds at a random point in the workout. It only does this once. This has never happened before across hundreds of rides/workouts.
I beta tested this firmware (and experienced zero issues) and it was explained during testing that it performs the zero offset upon going into auto standby mode. So this is after like 5 mins of no activity, but you can adjust it longer in the app. Whether that is still the case with the final release, I don’t know though.
I also had questions about when this process takes place and sent an email to them–got a reply back with no info, but saying they have forwarded it to the technical support group.
"I’m wondering at what point the auto-calibration occurs (before a ride, during a ride, after a ride?) and how it would be affected if shoes are left on the pedals? As a triathlete I (and many others) leave my shoes on the pedals at times and especially when I setup and leave my bike in transition to be ready to hop on and ride after the swim, and leave them on after I jump off to start the run. "
This pedals are getting better and better
Had an interesting experience. I’ve got a Tri bike with 155mm cranks and a road bike with 175mm cranks. I brought my road bike inside for winter training and always noticed some strangeness with the cranklength getting set back to 155. Turns out it was my Garmin 935 watch connecting to the pedals even if I wasn’t using it to record a workout that was resetting the cranklength. Just an FYI for anybody else, especially those that might only have a slight different (172.5 vs 175) on different bikes that you need to be aware of watches changing that setting on you.
First ride, power dropped at 11:00 mins exactly and lasted 5 seconds
Second ride, power dropped at 40:00 mins exactly and last 6 seconds.
Anyone know if there is a way to rollback firmware?
So far so good - two rides since updating and zero drops or issues 
No drops for me today either (little blip is me adjusting my shoe strap). Didn’t do the zero offset pre ride, but I’d also be curious to see how/when they do the offset and how accurate it is if not left in the 12:00/6:00 position. I don’t have another good power meter to compare them to, then again I’ve not compared to anything in a long time so wouldn’t even have a point of reference. Doing this workout felt fine though, at least in the sense that nothing felt grossly off power wise.
I’m no expert on these things but I would have thought that the best way to do an auto calibration would be to wake up the pedals (couple of turns of the cranks) and leave them for a minute or so to let them do their thing. Just jumping on the bike, clipping in and riding off (with weight on the pedals) doesn’t seem right… Or am I missing something?
From Favero Technical themselves from an email i sent for clarification
“It is necessary to complete at least one new manual zero offset calibration only after each new installation of the pedals, you can start your ride without any thoughts about the zero offset calibration”
The fact that I still dont know how exactly the auto calibration works and when it happens bothers me.
I think the users should know the basics of it, so they can behave accordingly
Or the system can be designed in a way that the user doesn’t need to do anything special.
Yes but that should be said in some satisfactory way:)
You know how cyclists brain work, we can stress about the smallest things:)
When I went to update the firmware, mine were not visible from the iPad app. I then grabbed my Android phone and was able to connect right away.
Thanks - will give this a go!
I have had my pedals since May 2018. I ride about 8-10 hrs/week throughout the year with them. I initally had some problems in that they did not “turn-off” when I stopped riding which depleted the battery very quickly. I contacted Favero who quickly sent me a firmware update that fixed the problem.

“So, just to be clear: with the new firmware update, I don’t need to do anything or even leave the cranks in a certain position (eg, 6-12)? I can just jump on my bike, start pedalling and the Assiomas will take care of everything? The only time I need to do a manual zero is when swapping the pedals between bikes?”
Hmm… the only time I have ever done a zero-offset is when I swap the pedals between bikes. Those were the instructions when I got them 3 years ago.
As far as the hop on the bike and go notion, if you’re moving the bike before you get on chances are the pedals are waking up in the process anyway. If you aren’t, they aren’t pairing to your headunit right away since they are not awake (Ive had this happen when leaving a cafe stop) and you don’t get power and cadence readings for about 10 seconds
I have a habit to spin the crank backwards 1-2 rotations before setting off to give the pedals time to wake up and reconnect to the wahoo. Assuming the auto calibration happens as soon as they are awake before load is applied.
True it doesn’t take more than a few seconds to manually do the offset calibration, but it’s nice to know the auto function is there in case I forget I don’t have to worry “are my numbers totally off”
