Stick on Garmin adapter?

I'm sorry if I'm giving you the wrong impression. I haven't said it's simple but that it should be possible. I would say I have yet to find anything that is difficult to achieve on a Wahoo. A quick Google for "display mahle x35 battery level on wahoo elemnt" delivers the instructions below. The same Google search showed me a Facebook page where Ribble users are discussing how they can view e-battery levels on their Garmins. This is a very basic function when using an e-bike. I'd be surprised if a Wahoo doesn't offer the feature.

I've done my best. Good luck.

Steps to Display Mahle X35 Battery on Wahoo Elemnt

1. 1. Pair your E-Bike:
   • On your Wahoo ELEMNT app, go to Settings > Sensors.
     
     
   • Turn on your Mahle X35 e-bike and make sure your Elemnt is on and the bike is in Bluetooth range.
   • Look for a new sensor named "E-BIKE" in the Unsaved Sensors list and select it to pair. You might be asked for a PIN code found on the bike's TCU controller.
     
2. 2. Add the Battery Data Field:
   • In the ELEMNT App, navigate to Settings > Pages.
     
     
   • Select the page where you want to add the data.
     
     
   • Select Data Field and scroll down to the E-Bike or Power section.
     
     
   • Choose the "E-Bike Battery" option to add it to your screen.
     
3. 3. Check the Battery Level:
   • The Elemnt device will now display the e-bike's battery percentage directly on your chosen data screen.
     
     
   • You can also check the battery level on the Mahle iWoc controller on your bike's frame, where a colored LED will show the approximate charge (White for 75%+, Green for 50-75%, Amber for 25-50%, Red for <25%, and flashing Red for <15% or <10%).

I have paired the e bike and added a new page. But I don't see any data fields relating to ebike or battery levels

Edit. I have now got it too display some battery data ! Problem is this is showing a significantly different figure to the BC900 .
Although the mules remaining is showing the same.

Back to the stick on Garmin thingy !!!

At the risk of repeating myself. Wahoo doesn't display the e bike battery level. Even wahoo themselves say this. I believe it shows on some garmins - but even then the accuracy seems sketchy.

Problem with the iwoc controller is that it uses colour coding to display the level of assistance as well as battery life. It's early days but I haven't got my head around assistance level v battery life from the lights.

Ok fair enough, though it seems an odd omission on Wahoo’s part to me.

When you change assist level, the iWoc colour indicates the new level for a few seconds, then it goes back to a steady colour showing the battery level.

Oh right. That makes things a lot easier. Dunno why decathlon couldn't put that in the instructions!

@kingrollo, this is a page from the Gain manual. There's one other colour it doesn't mention: it goes blue just when the bike is connecting to external devices like a phone or cycle computer.
