Hello, please troubleshoot in the following ways:
First, confirm whether the device is shared with you by others. Shared devices cannot be used as execution actions for Automation or scenes for the time being.
If the device is not shared with you by others but the corresponding device or its functions cannot be found, it is because this product does not support adding them to Automation and Tap-to-Run.
If the device can be found but some functions are missing in the function category, it means only the displayed functions support scene linkage.
The options for devices and their functions in scene linkage (Automation/Tap-to-Run) are set by the product manufacturer. If you want to add support for scene linkage (Automation/Tap-to-Run) for more devices or their functions, you can feed back this problem to the product after-sales team for their subsequent improvement. Thank you for your support and understanding.
