Favero Assioma Troubleshooting Guide: Fix Connectivity & Power Issues

You just want to ride. You’ve got your kit on, your shoes clipped in, and your Favero Assioma pedals are on your bike, ready to give you the data you need. But then it happens. That all-too-familiar moment of dread. You look down at your bike computer, and the power reading is either a big, fat zero or it’s bouncing around like a panicked ping-pong ball. Ugh.

We've all been there. That little knot in your stomach when your trusted piece of tech decides to act up. Favero Assioma pedals are awesome—reliable, accurate, and easy to use. But like any sophisticated gadget, they're not immune to the occasional hiccup. The good news? More often than not, the problem isn't a faulty unit. It’s a simple connectivity or setup issue that you can fix in minutes.

Consider this your go-to guide, written like I'm explaining it to a buddy over a post-ride coffee. We'll walk through the most common pain points and how to solve them, from zero watts to baffling dropouts.

The Most Common Culprit: The "Zero Watt" Problem

This is probably the most frustrating issue. You’re spinning away, you feel like you’re putting down some serious power, but your screen says… nothing. A big goose egg. Before you panic and start drafting a support email, let's run through a checklist.

Is the Pedal Awake? Assioma pedals have a smart auto-off feature to save battery. They “wake up” when they sense motion. The simplest thing you can do is just spin the cranks backward a few times, maybe 5-10 rotations. This little action is often all it takes to get the LED lights to blink and the pedals to start broadcasting. Seriously, don’t underestimate this one.

Check the Battery! This might seem obvious, but it's easy to forget. The Assioma app is your best friend here. Open it up, connect your pedals, and check the battery status. The pedals are rechargeable, and while the battery life is fantastic (around 50 hours), if you haven’t ridden in a while or you forgot to charge after a long weekend of riding, you might be running on empty. 

Bluetooth vs. ANT+ This is a big one. Most modern bike computers and apps support both ANT+ and Bluetooth. But you can only be connected to one device at a time via Bluetooth. For example, if your pedals are already paired to your Wahoo Elemnt Bolt via Bluetooth, your phone won't be able to connect to them simultaneously. This can cause some real confusion.

The fix: Make sure your pedals aren't connected to a different device. If you're trying to use your pedals with Zwift, and they were last paired with your Garmin, make sure the Garmin is either off or the pedals are "forgotten" from its sensor list. I've had this happen and spent a good ten minutes troubleshooting before I realized my phone was secretly connected in the background.

Pro Tip: For most bike computers, connecting via ANT+ is a bit more stable and allows other devices (like your phone) to connect via Bluetooth to the pedals at the same time. The pedals broadcast both signals simultaneously, so use that to your advantage.

"My Power Reading is Way Too Low/High!" (The Halving/Doubling Issue)

This is a classic problem for Favero Assioma UNO owners, but it can also happen with the DUO if the head unit is misconfigured. You look at your power numbers and think, “There’s no way I’m that weak today!” or "Wow, I just set a new FTP record... while riding into a headwind?"

The Reason: A single-sided power meter like the Assioma UNO measures the power from one leg and sends it to your bike computer. The bike computer is then supposed to double that number to get your total power. If this setting isn't enabled, your power will be exactly half of what it should be.
The Fix for UNO Users:
- Open the Favero Assioma app.
- Connect to your pedals.
- Go to the settings page.
- Look for a "Power Halving" option.
- Make sure this is disabled. Your bike computer should be the one doing the doubling.
-Now, check your bike computer settings. Most units (Garmin, Wahoo, etc.) have a setting for "Single Sided Power Meter" or something similar. Make sure this is enabled. This tells the computer to take the single-sided reading and multiply it by two.

What if I have the DUO and the power is off?
This can happen if your bike computer is trying to double the signal from your DUO pedals for some reason. The DUO already sends a combined total power, so if the computer is doubling it, your numbers will be way too high. Go into the sensor settings on your head unit and make sure any single-sided power meter options are turned off. It should be connecting to a "Dual" power meter.

The Ever-Annoying Connection Dropouts

You’re on a smooth stretch of road, everything is perfect, and then—poof—your power data disappears for a few seconds. The screen flashes "Power Meter Disconnected," and then it reconnects. Annoying, right? This is often a signal interference issue.

Are You Paired with Too Many Devices? As we touched on earlier, Bluetooth connections can be finicky. If your pedals are paired to your bike computer, your phone, and maybe even a smart trainer, you might have some crosstalk.
The fix: Unpair the pedals from any device you aren't actively using. If you only need to see data on your bike computer for a ride, go into your phone's Bluetooth settings and "forget" the pedals for now.

Signal Interference from Other Sensors This is a more subtle one, but it happens. If you have a chest strap heart rate monitor, a speed sensor, and your pedals all broadcasting on ANT+, they could be competing for signal.
The fix: The location of your head unit matters! Try moving your bike computer slightly closer to your pedals, perhaps to a more central location on your handlebars. A small change in antenna orientation can sometimes make a big difference.

The Calibration Conundrum (Zero-Offset Explained)

Okay, this isn't exactly a connectivity issue, but it's a huge part of the troubleshooting flow, and it’s something people get confused about all the time. Do you need to calibrate your Favero Assioma pedals before every ride?

The short answer: No.

The long answer: The Favero Assioma pedals have a fantastic feature called Auto-Zero. This means the pedals are constantly making tiny adjustments to ensure the power reading is accurate. They perform a zero-offset automatically whenever you stop pedaling for a few seconds. That’s pretty magical.

So, when should you do a manual zero-offset?

- After a fresh installation: When you first put the pedals on the bike, it’s a good practice to do a manual zero-offset using the Favero app or your bike computer. This sets the baseline after the initial tightening.

- When moving the pedals to a new bike: This is another essential time. A different crankset will put a different load on the pedals.

- If the temperature changes dramatically: If you bring your bike from a cold garage into a warm room, it’s not a bad idea to do a zero-offset. The internal strain gauges can be affected by temperature fluctuations.

How to do a manual zero-offset:

- Stop pedaling and unclip from the pedals.
- Keep your feet off the pedals and your bike upright.
- Open the Favero Assioma app or go to the sensor settings on your bike computer.
- Select "Calibrate" or "Zero-Offset."
- Wait for the confirmation message. Your head unit should show a message like "Calibration Successful" and a value, usually a low number close to zero.

One Last Thing: Firmware Updates

This is a classic "have you tried turning it off and on again?" but for your power meter. Firmware updates often include bug fixes, performance improvements, and enhanced connectivity.

How to check for updates:
- Connect your pedals to the Favero Assioma app.
- If there’s an update available, you’ll see a notification.
- Make sure your pedals are fully charged before starting the update. It’s a bad idea to let them die halfway through!

Final Thoughts

Look, it can be frustrating when your gear doesn't just work, especially when you're all set for a ride. But more often than not, the solution is simple and straightforward. Run through this checklist, and you'll likely find that your Favero Assioma pedals are just fine and you'll be back to logging those sweet, sweet watts in no time.

If you’ve tried all of this and you’re still having trouble, then it might be time to contact Favero support. But trust me, try these steps first. You’ll be surprised at how often one of these simple fixes is the magic bullet.
