I was running into the same issue using Google Chrome. I tried a different browser (Microsoft Edge) and a barcode did appear and I was able to successfully reauthenticate.

[Br00ster]

I'm having the same issue with Microsoft Edge unfortunately

EDIT: It worked with an in-private session in Microsoft Edge

In that case, it was most likely a caching issue within the browser. Clearing the browsers cache likely would have fixed the problem.

[Ehill05]

I was finally able to get it to work in Chrome, but it also wouldn't work in the Home Assistant android app.

[Martin-Dolan]

I got the qr code but it says it has expired when I scan it. How do I get it to regenerate a new one?

UPDATE: Restarting home assistant let's you regenerate a new code, and that works

I had the same issue Yesterday but now after entering the code I get a blank QR screen.
It's very hard to scan ;-)
I tried different browsers with the same result.

Same issue in Safari 16.6 (18615.3.12.11.2), but i succesfull scan QR Code from Chrome 121.0.6167.160.

I solved it like this:
Browsing through this extension, i already had this installed, i often use it to access the GUI's devices such as the Shelly when I am away from home.

No QR code, only white box - Chrome 121.0.6167.161 \ Yandex 23.9.5.721 corp (64-bit) \ Firefox (i`m tryed this https://github.com/mincka/ha-addons/tree/main/firefox)
Maybe problem with my region... RU?

Set HA to the default THEME and try again, And after that you can set your own theme again.

THIS was the solution! Guess custom themes have to be updated to support this :)

same issue on edge. i was able to view the qr code in firefox, however the code expired. as someone else here mentioned, restart HA to generate a new code.

Have you tried to change back to the original theme already?

[PachangaDad]

I can confirm, I was using Edge and using a theme variation. returned to Home Assistant theme and tried again, Bar Code appeared clearly black on white. Using my camera was able to scan within SmartLife app and had to try a few times of scanning and resubmit and scan again and resubmit iterations, eventually it took and was able to complete reauthorization. Key here is the using variations of themes does not display black and white barcode correctly. My success came about with going back to default selection of Home Assistant Theme for user interface. In my case it worked using an Edge browser. Just sharing my findings hoping to help out where I can.

[odinho]

Now that I have the QR code. How are we meant to actually scan it in the Smart Life app? It only opens the camera and I don't have two phones to do this with. Seems like a rather frustrating setup experience 😅

I guess I have to print the QR code to use the camera in Tuya app to see it. That's... Quite cumbersome. 😬

(it's the smart life app that needs to support reading screenshots, but possibly there is an on-device way Android intent to not need a QR code?)

[Martin-Dolan]

Yes, with only one phone it's a pain..
If you have a pc you can open it on there, and then use your camera, or invite a friend over for a coffee, sms them the code picture and then scan it on their screen.

One thing to keep in mind is it expires after a period of time (found that out the hard way haha). If you want it to regenerate a new QR code you need to restart home assistant or it will just keep giving you the old code.

I also tried looking at the text the QR code gives you, to enter manually, but it's totally different from the short number you can type in manually in the app so that doesn't work..

Another idea is to cast the QR code to your TV if you can, and scan it that way...
It is a bit of an issue with QR codes when there is no way to display it to scan it without two devices.

Perhaps there is a virtual camera app that can trick the scanning app into thinking it's looking through the camera, but actually looking at a gallery pic? Good idea for someone to write one if there isn't...

[Nezz]

I had the issue too. First, the QR code did not appear at all, which I fixed by clearing the browser cache. Then it was just a white box which was fixed by changing the theme to the original Home Assistant one.

[martin3000]

The private browser window did the trick for me.

[FJ-SA]

I removed my homekit integration and reinstalled it. Then it gave me all my QR codes. Only one problem persists out of 4 cameras. In HA and homekit it shows that the camera is not responding. But when i open it in tuya app it works perfectly. Anyone else experienced a similar issue?

No I set Home Assistant back to it's default theme and the problem was solved, And I could scan de QR code.

[FJ-SA]

Thank you for your reply. I don't think i have changed my theme but just to make sure, how do i change back to the default theme?

[Daytona3522]

Just go to your profile (Below notification in the sidebar) and there you can change the theme, language and way more.

[FJ-SA]

Thanks but that is not my problem. It is still on default 🙈 its just very strange that all other cameras work perfectly thats also under Tuya. Its just the one.
