Your Philips Somneo Sleep & Wake-Up Light can function normally without a Wi-Fi connection. This means that simple features like alarm are not affected by a Wi-Fi connection.
However, if you want to use your wake-up light with the Philips SleepMapper App, then it is important that your wake-up light and phone are connected to the same Wi-Fi network. In case, the Wi-Fi connection is lost, some data from that time period may not be visible on your app.
The features of your wake-up light which can be tracked by the Philips SleepMapper App are bedroom tracking, bedroom environment, weekly alarm schedule, powerwake and personalized sunrise.
