Can't activate Kettler S8 treadmill after pairingin App mode

Hi @all,

today I got my brandnew Kettler Track S8 treadmill, which is listed as a compatible device for Zwift running. My current setup is a WIN 10 notebook and Zwift Companion App for BLE bridge. This setup works fine for my TACX Smart smart cycling trainer.

When I connect my treadmill using “App” mode, the pairing works fine. Speed and cadence were found and selected.
But now I can’t start running on it because the “App” mode ignores speed and incline commands on the treadmill directly.

Does anyone has similar problems with the new Kettler treadmills?

Thx in advance

Can you explain what “App” mode?

After using direct bluetooth connection it works

Hi Sascha,

I have the same problem with my Kettler Track S8 treadmill. It’s not clear to me what you mean by “using direct bluetooth connection”. Can you do me a favour and describe it a bit more? I am using an Apple TV instead of a notebook. Do you mean with “direct connection” a connection to your notebook or “direct” to Zwift? Bluetooth is enabled but if I don’t start the “App” mode, Zwift doesn’t find treadmill.

Btw. Do you sometimes recognize some kind of noise (like groaning or squeaking) when starting with your training? During the first minutes my treadmill sounds a bit strange (seems to come from left front) but the noise disappears after some minutes of training…

Thanks for your further information

Hi Alex,

i’m not familiar using Zwift with Apple TV instead of the Windows Software. But in my case, I had to change the way how Zwift wants to Connect with smart Trainers. Normally I use the Zwift Companion App as the Bluetooth connector for my Trainer. But this didn’t work for the Kettler treadmill. I tried a Bit and changed the Connection Type to “Use Windows direct Bluetooth…”
So, when you can Connect the treadmill directly with your Apple TV, it should be the Same. I can change the Bluetooth Options at the “Connect devices” menu. There is an Icon in the upper right Position on the Screen.

Hope it will Work for you…

Hi Sascha,

Thank you for your quick reply! I just tried it out but Apple TV doesn’t find the treadmill when searching for Bluetooth devices. Afterwards I tried the iPad App and I was able to connect the treadmill using the Kettler “App” mode. It’s really a bit strange but I’ll look into it once again. Would be much more fun on a bigger screen.

See you on the track :wink:


Hey Guys , I have the same tredmill , is it possible to upload a specific work out?

You mean upload to the treadmill itself? Not sure, but I think it isn’t.

Good morning,

uploading the workout or any other way to make the treadmill follow a specific workout… ie an application that controls the treadmill …

Hi all,

maybe someone has the same problem with the Kettler S8/ Alpha Run 800: The connection with Zwift works fine and I can start to run, but after 5-10minutes the treadmill stops the workout and changes to main menue.

Its very annoying to start over every 5 minutes …
