Hello, friend!
The EG8145V5 does not support set automatic reboot.
If you need to restart the device, you can press the Reset button to reset the device.
Note: Press and hold the Reset button for more than 10 seconds to restore the device to its factory settings. Do not perform this operation if no obvious fault occurs.
Only the HG8145X6/HG8245X6/HN8145X6v supports the function of setting reboot on the WebUI.
Thanks!
