Same here. Integration is expiering (for some reason). Reconfiguring with QR code is failing, -> "Code expired". Therefore you have to DELETE the whole integration and ADD it from scratch... very annoying. Happening every 2-3 days?!

It happened to me and the workaround was to press submit button shown just below the QR code anyway. This popped an error message, about QR code expiration, just above the QR code image itself. Once that happened, I reloaded the page and a new, fresh QR code appeared. Scanning that with Tuya app was finally successful.

I hope my workaround will help others.

I still consider this user experience to be couterintuitive and cumbersome, so @tuya , or any of the other code owners, should fix it.

I just had the same issue. Surprisingly even restarting Home Assistant wasn't enough to resolve the issue, but @dubrox's submit button press did the trick.

@dubrox You're an absolute star, thank you for discovering that!

HA said I needed to 'reauthenticate', so tried to in the SmartLife app and it said 'non mobile device' and it had expired when I scanned it...

When I saw Login error (E0020002): The QR code has expired, please close the page and reinstall the integration. I was like please nooooooo, reinstalling integrations breaks everything even if it works you have to spend time renaming everything... so thank you very much! Clicking submit on the QR code, then coming back out of it all, and going back into reconfigure, then scanning it with the app and it's all fixed :) I'm using 2024.06.02 (not updated to the latest yet).

I do mostly use localtuya for not having to deal with this kinda stuff, but the climate stuff still doesn't work too well with it.

Like Dubrox wrote, When you get Code expired in tuya phone app, click submit in home assistant. that action will build a new QR.

@ dubrox Much appreciated!

This will solve the problem (for me at least)

Click on your picture/name on the bottom left, look at the theme and change it back. I had to change it from black to light and then try again with the QR code.

I just faced the same issue. The workaround from here did the trick: https://github.com/home-assistant/core/issues/115250#issuecomment-2224591373

Core 2025.1.2 still has the same issue.

The workaround from @dubrox works! Thank you!

Issue still exists, fortunately the workaround from @dubrox still works.
