How to hide or unhide the device?
Why is the voice function on the control panel not working?
After clicking factory reset, why is the version different?
Why is the control panel unable to perform voice control on sub-devices?
When I scan the QR code to add the central control panel in the App, a message "You cannot scan the QR code to add a device deployed in another data center." is displayed. What should I do?
