The Momcozy Sunrise Sound Machine, which includes the product with the manufacturer ID «WN008-GW12BA-A,» does not explicitly require WiFi to function as a basic alarm clock or sound machine. However, some features might be enhanced with WiFi connectivity, such as synchronization with other devices or app control, but this is not specified for this particular model. For models like the Momcozy Smart Baby Sound Machine, WiFi or app control is mentioned, but it seems to be more about remote control and customization rather than a necessity for basic operation.

If you are concerned about specific WiFi requirements for your device, it would be best to consult the user manual or contact Momcozy's customer support for detailed information.
