It is not possible to leave the light on blue all night without it going out, as the colour options available do not specifically mention blue. However, the nightlight does offer colour changes and can be used with timers, which could be useful for managing how long the light is used.

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.

There is no specific snooze function in the information provided about the product. The available functions include an alarm, light and timer, but no explicit snooze function. If you need more details, I recommend contacting the official product description or the manufacturer.

The time can be switched off through the night as the brightness of the time display can be adjusted. The display can be set so that it is not too bright or even switched off completely to improve the quality of sleep.

No, the Momcozy Sunrise alarm clock does not have a "sunset function". The alarm clock only simulates the sunrise with soft yellow light and soothing melodies to provide a peaceful wake-up experience.

The Momcozy alarm clock only works when it is connected to a power socket and not on batteries. It is an analogue alarm clock as it has no radio functions.
