I faced the same situation.
I hope anyone can help me with this ticket.
I have devices that need to be connected using the Smart Life app with Tuya Hub among Tuya’s products or OEM products.
I also have Tuya Hub for testing, but if I know how Hub detects the device, I think I can connect to HomeAssistant. (I think I can connect to Wi-Fi afterwards if I connect to BT first, and support Wi-Fi)
However, as long as there is a problem with the local key, it will be able to get the local key from the Tuya IoT.
I am facing the same issue … we have Tuya OEM app (white label one) … but cant use HomeAssistant Tuya Integration with it …. I enter the user code, then i get error message when i scan the QR code with my tuya OEM app (which is based on Smart Life) ……
I added the same devices to Tuya official app, and i easily made the integration work and all devices were discovered … but this is not a solution as in this way we have to throw away our tuya OEM app ……
Anyone managed to link tuya OEM app to HomeAssistant Tuya integration ?
