FAQs

Why does a paired device not appear in the device list?

Your own app, your own mini program, Tuya app account, and SaaS apps have completed the network pairing for the device and linked with the specified apps, but the device does not appear in the list. In this case, you can try:

• Method 1: Go to the Devices details page of the cloud project, and switch to your desired data center in the top right corner. For more information about data centers, see Mappings Between OEM App Accounts and Data Centers.
