How Do I link my app account using Android? I have NO scan option
So I can’t scan the QR

(I went to ME (right bottom) and there are NO scan options

On iPhone it’s an icon that looks like this [-] in the top right corner

Thanks,

That should be corrected in the instructions.
There it’s mentioned as “Scan”

This solved my issue!

Hello, have also this problem, but recreation of project and reinstallation of Tuya v2 integration didn’t help.
I’m wondering, what permissions did you guys set for the devices on import to iot-tuya.
Have complete set but skill_id invalid…

I have fixed the problem by unlinking the app and link it again without any changes, creating new projects etc…

Confirmed, this worked for me. Wife and children happy again :relieved:

Happened to me today. All I did was unlink the app in tuya cloud website, and re-link it directly.
Reload the integration in HA and voilà
Thanks for this thread!

Had this problem since yesterday, this fix worked for me today, thanks!

It did it to me last night, too. I resolved it by going through the process of creating a new cloud project in Tuya IoT and then adding a new Tuya integration into HA with the new details, then disabling the original one. Devices have all come back with the same names, thankfully, so no need to change any automations.

It’s prompted me to look at LocalTuya, but that’s an even bigger nightmare, it seems.

It worked. Thankyou!!

Hello. I tried to do this but in smart life it says without permission in the integration… why is it?

16

No need to create a new project.

What I did was:

  • unlink project from “Smart Life” App
  • go to tuya ios development website
  • go to cloud section
  • clicked on my already existing project
  • go to tab “Link Tuya App Account”
  • then “Add app account”
  • then I opened the Smart Life App and I captured QRCODE that tuya website was showing
  • grant all devices all permissions (read, write, management)

that’s it

Home Assistant now can manage back all Tuya related devices!

Thanks for the detailed instructions. I did the same thing, except clicked unlink button in Tuya Cloud page. Worked just as well.

The problem started for me today when I added a png picture file to the Home Assistant www folder, and then restarted HA. Any idea of what causes this error to begin with.

Eventually I would like to get rid of using the Tuya cloud integration, but for some reason, I can’t get some of my temperature/humidity sensors, garage door opener, front gate opener, thermostat, and light dimmer to work reliably with ZigbeeHomeAssistant or Tuya Local.

I got this problem. Just unlinked the tuya app and re-link, all working again. No idea what the cause is.

I keep seeing people say to unlink the app, but where is this done? I’m not seeing an option at Tuya Smart Developer Center

1. Navigate to Tuya cloud: https://eu.iot.tuya.com/ (mine is on the eu region, yours could be in another)
2. Login
3. Click Cloud icon
4. Click Devices in top menu
5. Click Link Tuya App Account in submenu
6. Click unlink, 
7. Click Add App Account button, 
8. opened the Smart Life App and captured QRCODE that tuya website was showing 
9. grant all devices all permissions (read, write, management)

Overnight my Tuya integration starts working again without any intervention. :wink:
Definitely a Tuya side issue.
