You have no sleep data in the Withings App

If you have no sleep data in the Withings App:

1. Make sure that your ScanWatch Light appears in Devices in the Withings App.
   If not, you need to install it.
2. Select Devices in the Withings App and make sure that your ScanWatch Light is Connected. 
   If not, try to turn off Bluetooth on your mobile device and then turn it back on.
3. You'll know that the connection with your ScanWatch Light has been established when you can access the Upcoming alarm selection screen. Your data should then start syncing.

Important note: We have chosen to disable the detection of naps to focus on an improved tracking of your nights. As the sleep function requires at least three hours of sleep in order to track data, sleep periods of less than three hours are not currently tracked.

Part of your night is missing from your sleep data

If the beginning of your night is missing from your sleep data, it may be because you move a lot in your sleep. ScanWatch Light can be quite sensitive to motion until it is certain that you're asleep. This can affect the beginning of your sleep data.

If the end of your night is missing from your sleep data, it may be because you got up in the middle of the night and did more than 150 steps. Walking more than 150 steps after being asleep stops the sleep algorithm. If you go back to sleep after that, your sleep data will still be detected but it'll be considered as a nap.

Your data seems inaccurate

If your data seems inaccurate, it may be that:

• You're also using a Withings Aura to track your sleep. If you use both devices, sleep data coming from the Withings Aura will systematically overwrite any sleep data coming from your ScanWatch Light. Note that if you use a ScanWatch Light as well as a Sleep / Sleep Analyzer, your sleep data may be presented in a different way.
• You're wearing your ScanWatch Light in your pocket, in which case sleep can be falsely detected whenever you stop moving. We strongly suggest that you wear your ScanWatch Light on the wrist.
• You have an unusual sleep pattern due to health or work-related situations.
