Doing the above remove / relink has also worked for me as well and its back working!..
But, I am still seeing the above in the logs with AuthType error log message and also seeing
2022-10-23 08:55:18.776 WARNING (MainThread) [homeassistant.components.number] custom_components.tuya_v2.number::TuyaHaNumber is overriding deprecated methods on an instance of NumberEntity, this is not valid and will be unsupported from Home Assistant 2022.10. Please report it to the custom integration author.
Anyong have any ideas how to address these log messages?
Mine was hideious.
I made a new project as it sort of looked like that would be thing, and added it as an app. Thay wasn’t able to find any devices to I went and removed authorisation on the old project. Then I removed the it in the app to add it back and got errors about having 2 projects already authorised. You can’t delete projects and I removed all teh authorisations I could find anywhere but never made any progress.
So I changed my registered app email address, and made a new Tuya account with the new address, and did it clean. Now I have devices. Automations have got the devices but aren;t sure what the actions are, so some fixing to do, but it’s otherwise back.
I was about to delete the entire house in Tuya and go re pair every device if that hadn’t worked.
