Computrainer not found in new Pairing Screen [Sept 2025]

Well, Shuji I understand that the support is handled by AI, but Zwift set it up that way, not me. You act like it was unreasonable of me to accept what your own support system told me. If we can’t trust what your support says then there is no support from Zwift at all. Maybe don’t put a condescending AI in charge of customer support and actually fix problems instead of dodging them.

I too am in the same boat. no warning, just another upgrade and BOOM no computrainer support. I agree that it is old and legacy. but IT WAS WORKING. What about a depracation path or something.

It makes no sense that zwift would not support Computrainer because it’s old when at the same time it supports dumb trainers.

It sounds like this was not intentional and they are looing into why it happened

I thought that too, Mike, but the AI said that Computrainers were being phased out and someone had to program the AI for that response. Either way, they claim they are going to fix it. I hope that is true and that it doesn’t take them too long.

Not necessarily, LLM-based agents are well-known for “hallucinating” (making up) stuff. I don’t know whether that’s the case here, but it sounds like Shuji is trying to urgently get to the bottom of it.

yeah isn’t the entire point of AI that you don’t need to program it, it figures things out on its own?

Well, that makes it even worse… Zwift put an AI that makes stuff up on its own in charge of customer support! So when we need help we can’t depend on the response being helpful or even true?

don’t take my word for it, I have no idea how any of it works… its just magic as far as I know

AI or not, you’d likely have got the same result.

I’m not defending it, in fact it’s a frustrating example of level 1/2 support of many help desks, whether it’s human or AI. What you tend to get are scripted answers from the product doc or the FAQ. So, if your answer isn’t in any of those (RTFM), you’ll often get “it’s not supported”, or “that’s how it is” sort of responses.

In terms of what happened, as Mike indicated, the responses from Zwift suggest they didn’t know about this either. As a guess, what may have occurred, is that someone was cleaning up some code, they came across support for serial devices, thought “What’s that, no-one uses that now”, so they deleted not knowing that CompuTrainers are built like tanks and not having checked any telemetry, because there is always someone, somewhere, still using some old API or interface.

Zwift clearly messed up, they ought to owe you some kind of recompense or rebate, but they do seem to be looking in to it.

Hello all,

We’ve made a backend change for the folks who have written in or posted here on this thread reporting an issue pairing Computrainer or similar devices. Please be on the lookout for an email from Zwift Support and let me know the results of your next Zwift session.

Thank you Rowdy for looking into this. I am also a computrainer victim with an annual membership. I have three friends now with the same dilemma. I managed to connect my power pedals, heart rate and speed/Cadence sensor and chose unlisted trainer like one of your experts recommended but I have no trainer resistance. We appreciate a fix if there is one. Otherwise, my guess is it is time to move on to newer trainers. We appreciate your help. Some of us here have been members of your platform since you launched it with only Watopia routes. Cheers

Nicely said. It is frustrating but I have been with Zwift since they launched pretty much. Bought my computrainer in 2004 and joined them the second year they launched when they only had Watopia. I trust they will find a fix asap. They always figure it out. Cheers.

There’s a good deal on the Zwift Ride and Kickr Core 2 right now, lowest price ever.

I just got on and took a short test ride and it worked. It took a few reboots and and longer to connect than normal, but whatever patch you slapped on the problem did the trick.

Is this a new thing? It’ll be fixed for only those who wrote into support or posted on this forum?

Hello Rowdy.

Is this issue fixed now. ?

Hello @Timanda_Clark is this fixed for all now?

I bought 2 Computrainers in 2000

They have been flawless

Those trainers are rubbish compared to Computrainers

I have been in Zwift since it was a beta

Every other power trainer has had multiple issues - especially the Kickr…

But Computrainers just work…

Thx to Zwift for helping resolve the issue

One question for the Zwift team - will this fix cause other issues with further updates ?
