same thing happening with me. :(

[wwelles]

I don't really know, but I speculate that Tuya is being overwhelmed. Would suggest others try later in the event this is the case.

At me don't work:

[Y4nnickB]

Same thing here... Invalid hex color

[wwelles]

I'll add that when I click the reauthenticate to get this popup there is a network call made that seems to look legit.

[pxFIN]

Same error but i just closed the error window and reconfigured again.. QR code became visible and authentication in smart life app successfull

[antkowiakit]

Same problem here, for new integrations too.

I ran into this same issue. As a workaround, I copied the "data" string from the API request that is sent when the popup opens, used it to generate a QR code in an external app and scanned it with the Tuya app. After that, all I had to do was clicking on "submit" on the popup of on the homeassistant app and the integration was working!

Changing theme to default worked for me ! To change theme, click on your user name on the bottom left and then change theme to "Use default theme"

[Y4nnickB]

Changing theme to default worked for me ! To change theme, click on your user name on the bottom left and then change theme to "Use default theme"

This did the trick for me too! I had to choose the "Home Assistant" theme, as for me the default theme was a custom theme set by an automation

[wwelles]

I had to select the Home Assistant Theme and then it would've worked however it had been too long so I also needed to restart home assistant and re-enter my User Code

[yshrik]

Yes, changing the theme to the default one helped generate the QR-code. Thank you!!!

[jezzaaa]

I get the "Login error (0)" message (same as @Liionboy), not the "Invalid hex color" message. I use the default theme. I tried restarting HA, and was asked again for my user code, but then get the same error.

I managed to get this working. I wondered if the app was interfering with my local devices (although not sure how this would be a problem here), so I turned off the wifi on my phone, retried the reconfigure, and the QR code appeared. The app said the QR code had expired, but I tried a couple more times and it worked. This work-around doesn't make sense to me, and I'm wondering if it was simply the Tuya servers being overloaded, and I simply needed to try a few more times.

I'm not getting a QR code, but no error message either:

[SerkanAkcadag]

Clear browser cache and try again. the problem will be solved

[RedZebra123H]

Clear browser cache and try again. the problem will be solved

Thank you so much this worked! I used an incognito broswer window.

[psfales]

Tried again a while later and it worked. AFAIK, I didn't do anything different (like clearing my cache), so maybe it was something on the Tuya end, or maybe just waiting a while.

[odjhl88]

Yes, changing to the default Home Assistant Theme also worked for me.

[FMeinicke]

For me changing the theme color from "Auto" (which would choose the Dark theme in my browser) to "Light" shows the QR code. Leaving this out there for those who don't have any other themes installed (like me) and are already using the Home Assistant Default theme.

This is a frontend issue, which is here:

duplicate of https://github.com/home-assistant/frontend/issues/19722

Also, #80278 (which is pinned in our issue tracker), is a catch all.

The workaround is, to temporarily switch to the default theme to re-authenticate.

I have tried changing the theme, clearing the cache, using a private window, giving it permission for pop-ups, etc.... and I can't do it. I see a 500 error in the development window.

[frenck]

That is not the same issue as reported in this issue. You have a different error message than the person reported in the opening topic / issue description.

[Adriien-M]

I guess it's a frontend cache problem, a simple F5 did the trick for me

[jarucho]

same here

I cannot switch switch to default theme so... no solution for me

Then there is no solution at this point. Any customization outside of HA is generally unsupported. We do our best to make things work but can't guarantee it with custom modifications.

Please follow the above linked issues for progress.

In my case, I temporally stopped https then barcode was shown.
