"Failed to set up" after machine reboot or HA restart while internet is not available

[artem-zinnatullin]

Hi!

Almost every time after machine reboot HA boots normally, but localtuya crashes with Failed to set up and doesn't reload automatically causing ALL Tuya related automations to fail.

Environment

• Localtuya version: 5.2.1 HACS
• Home Assistant Core version: 2024.1.3

Steps to reproduce

1. Reboot the machine sudo restart
2. Wait for Home Assistant to boot
3. Navigate to Integrations
4. Observe localtuya Failed to set up

Or:

1. Cut off the internet from the machine
2. Restart HA
3. Navigate to Integrations
4. Observe localtuya Failed to set up

Provide Home Assistant traceback/logs

Additional information

To fix the issue I have to manually navigate to Integrations -> localtuya -> Reload.

Few thoughts:

• Integration should gracefully reload itself in such a case
• Integration should NOT fail if openapi.tuyaus.com or other Tuya internet API is not available, simply because it's a local-first integration. No one wants their home not to work if some external API is down, that's why we do localtuya!

Just to add to this my internet went down for 15 minutes, when it came back localtuya had failed to load and my devices were offline. HA hadn't been restarted so it was just a case of the internet dropping for me causing the issue. A re load of localtuya resolved the issue, but i put this on so it would work offline!!

I also have this issue. Localtuya "failed to set up" with no internet regardless of how many times I restart. I managed to make it by work by in configuration, reconfigure the cloud api access and selecting do not use cloud api. It now works smoothly, though will likely need cloud reconfiguring to easily add new devices.

This should really be something that doesn't prevent the integration from setting up or running at all though, I would have imagined it would be an easy thing to detect if there is no connection and skip the cloud api polling which is only required for easy adding of new devices.

I had a similar problem when adding a new device. But restarting the integration did not help. Is it possible to somehow solve this without removing the integration? I do not have a current backup copy.
