I’m also patiently waiting for the firmware rollout. Seems to take a long time.
I installed the new firmware earlier this week and it has been solid on the 2 rides I’ve done so far. I don’t have to connect the hub through the companion app anymore and it paired with the app seamlessly. I don’t know why communication is such an issue with Zwift around this whole upgrade process, but at least the new version looks to have resolved what 4.0.0 broke. Hopefully it’ll finish rolling out soon.
I expect they’re seeing how many units get spanked by the upgrade and, of course, general feed back on 4.01 too. Been quiet here since 4.01 - seems much smoother than 4.0 was. That said a rough time line would help people a lot. 20 percent rollout achieved, next round April 12th etc.
Is Zwift trying to get Worst Support Award? Two months now since 4.0 and Autocalibration was announced…still waiting…
Why don’t I get the update to 4.1?
Just got the eMail that version 4.0.1 is available for my Zwift Hub.
Tried to install the update via Zwift companion app (newest version).
Process went to 100% then showed error “Update failed”.
Now the Zwift Companion app shows Firmware version 0.0.0 .
When I try to update again the process starts with “Starting DFU…” but goes do “Disconnecting …” after a few seconds.
The Hub also does not connect to my PC with the Zwift App anymore !!
What to do ?
You definitely need to contact Zwift support.
I finally got the firmware update and it installed with no problems.
Still waiting for the game update though. Oddly I got it on a windows 11 laptop, but not on the windows 10 laptop I use for Zwifting
Mine got to 66% then failed. Had turn off and power up the turbo a few times before it would connect again. Then managed to resume the update.
Managed to revive and update my Hub with the help of another smartphone.
Glad it is now on 4.0.1 and it connects to the Zwift App again.
UPDATE April 14
Hub firmware 4.0.1 has been released to 100% of Hub owners. Follow these directions to update the firmware.
Please pay attention to the callouts on that article - like giving the Companion app Locations permissions so it can use the Bluetooth radio to communicate with your trainer, for example.
If you are having issues after following those instructions, some Zwifters have reported success by:
- Uninstalling the Companion app, rebooting the phone, and re-installing the Companion app.
- Using a different smartphone to run the Companion app to update firmware

First ride on 4.0.1 earlier today. I welcome the auto calibration but the base resistance in sim mode on the flats is still too low.
My ever so slightly older than 30 day hub is now a piece of modern art. It never worked great. I never had a ride where I didn’t start only to get a lost connection message forcing me to stop, reconnect and start again, but at least it always worked the 2nd time.
But today I tried to update firmware hoping this might improve things. Instead the update crapped out, and now the unit has the blue connected light even when the device I used with it is off. It won’t take another attempt to update. It won’t connect to a device, and the support chat is an insulting loop of how to videos that don’t cover anything substantive.
If it was less than 30 days, I’d want a refund. As it is, I’m trying to make a warranty claim, which apparently needs an email. There’s no easy form. The “support” is true ■■■■■■■ design, intentionally difficult to use in hopes that you give up
I’m tempted to see if my credit card company can cover the warranty and make them deal with Zwift. They sold a piece of junk. I see now why it was cheaper than other hub smart trainers. Id say you get what you pay for, but I’ve gotten far less than that.
Ask for a refund anyway if that’s what you really want. Stick with the support process as it’s your only way out.
The Hub is my first Smart Trainer ever and I never had issues with it. Rode 5-7 times a week with it. Even the Firmware updates went fine. I just noticed one odd behaviour:
- Hub connected to Surface via Bluetooth: No problems
- additionally running Companion App on Mobile: No problems
- additionally Buds connected to Mobile and playing music: Connection losses on Hub after a while
If I connect the Buds to the Mobile without starting the Companion App, no problems. I could replicate this behaviour. But it doesn´t bother me.

The directions they are giving go counter to almost all software debugging workflows and a process where a mobile device can screen time out and brick a unit is a critical design flaw.
Yeah that’s what happened to me. I was lucky I reopened it and was able to resume from where it stopped. Pretty poor.
I’ve had my hub about a month.
The hub had an issue from the get go in that every ride – literally 100% – required me to start, then I received a no signal message inside of three seconds, then exit the ride, reconnect, and start over. It worked on the 2nd attempt to start each time, so while annoying, I could use it. I wasn’t sure if it was a hub issue or a software issue, so I decided I could wait for a patch.
Yesterday, I got the message that there was a firmware update. I was hopeful that this would solve the issue and attempted to upgrade the firmware. The firmware update started but failed to complete and sat at 0% with a ‘disconnecting’ status on my notifications and red light on the device. It stayed like this for 20 minutes or so before I force quit the app.
I tried it several more times. Same result. Start, almost immediately goes to the disconnecting, never changes.
I tried uninstalling and reinstalling the companion app (support tells me this was my mistake – never do this – despite this being what anyone who has worked with debugging software issues knows is up there as the first thing to do).
Chat support was worthless. They sent me the “have you tried” web pages. I tried those again, or those I could, as the ‘don’t uninstall the companion app’ was too late [this is a serious design flaw if this is such a significant problem] and somewhat contradictory to the their “uninstall and reinstall the game” suggestion for clearing user data.
I told them none of that worked. They told me they were transferring me to another support level, but that just sat there forever waiting for someone to come on. I emailed support. They send sent me the same instructions that I received from chat. I emailed back.
I’m waiting…
Sadly, slightly more than a month else I would just return the paperweight for a refund and buy from a reputable hardware company with real support. I really enjoyed Zwift but it feels like I made a terrible, terrible mistake buying the hardware from them.
couple of questions… how are you connecting? BT or ANT? have you looked at different interference issues that can occur with those two connection types?
