No, all the pairing steps are done within the app, you just need to allow the app to access your smartphone’s Bluetooth

You should install the logo on the pad facing up, positioned at the level of your heart.

The device should be covered by a mattress cover to prevent slipping during your sleep.

Yes, the bump in the middle of the pad is the motor, it is used for sleep induction and the alarm. If the pad is covered with a mattress cover, the bump should not be noticeable by the user. If you still feel it, you can lay a blanket over the mattress cover up to 3mm thick, and the sensor should still be able to detect you.

The cover over the pad should not be more than 3mm thick in total.You can use the biosignal test in settings -> device settings -> my device to confirm that the device is picking up your biosignals.

• Solid blue: power on
• Blinking blue: device pairing
• Solid teal: device in normal mode
• Blinking teal: device in low power mode
• Solid green: device has hardware issues
• Blinking green: Wi-Fi is disconnected

1A) Solid green lighting

The device needs to be repaired if critically damaged, but may be functional in most ways (for example, only the humidity sensor may be damaged)

1B) Blinking green lighting

If Wi-Fi is continuously disconnected: the device has a range up to 10M depending on the Wi-Fi router, you may need a Wi-Fi extender to make it work if this is the case

This occurs when the sensor cannot detect the user for many parts of the night. The sensor may have slipped while you slept, or you may have moved around your bed a lot, leading to missing data. Adjusting the sensor and making sure that biosignal can be detected using biosignal test may help with this error.

The sleep induction vibration is very weak and can only be felt when there is no noise around. If you don’t feel it even in complete silence, you may need to increase the strength of the vibration in your settings. The vibration strength should be adjusted such that you feel and hear it, but it does not keep you up.

The alarm increases in strength gradually over time starting at the set alarm time. This means that the user may not feel it at the beginning. If you don’t feel the alarm after 2 minutes, set the alarm vibration strength to maximum first, and gradually reduce the strength so that you’re comfortable with the vibration.

No, if you want to delete your data, you need to delete all of it.

We do not have this yet, but this will be updated in mid-2024.

The device is supposed to reboot every hour when in low-power mode.

If your device keeps resetting itself, it may be that the update wasn’t properly installed. To factory reset the device, please follow the video from 00:03:20.

After factory reset, the device needs to be re-paired to your account.

The device should not be plugged out after you sleep, it sends a trigger to calculate your sleep characteristics 5 minutes after you leave your bed, meaning that if you pull your device out of power during this time, your data will not be calculated.

The device is only able to measure sleep over 3 hours long, and displays the longest sleep in your app. (i.e. naps are not displayed)

This is because our A.I. was trained on polysomnography studies, all of which are over 3 hours long. We could make the A.I. predict sleep less than 3 hours, but the prediction would be very wrong, so in order to maintain reliability, our device currently only displays the longest sleep of the day which is over 3 hours.

1A) I slept over 3 hours and did not get data.

If you did sleep over 3 hours and the data is not displayed, this might be because the device was not able to detect you during your sleep – for example, you rolled out of the range of the device.

The way that the sleep measurement works is in two steps: 1) It estimates when you actively started to sleep and woke up by detecting movement, 2) It estimates sleep characteristics between these two points using A.I. trained from polysomnography studies. If the user is moving around a lot and stops moving, the A.I. might take this time as the starting sleep time.

2A) How do I minimize sleep measurement errors?

To minimize sleep measurement errors, do not hang around in bed for hours before starting to sleep, and try to sleep on top of the sensor the whole night – as if the sensor cannot detect you, it will not be able to predict your sleep correctly.

• Well/Poor Balance:

Your sleep has 5 characteristics, including duration, deep sleep, efficiency, latency (how long it took you to fall asleep), and wake-up state. If any of these are much worse than other ones, we consider this a poorly balanced sleep, and vice versa.

• Efficient/Inefficient:

Sleep efficiency is correlated to how long you were awake after you started sleeping. For example, if you were asleep 100% of the time, your sleep will be very efficient. One caveat is that you might have felt like you were asleep the whole time, but you may have been awake physiologically, or woke up briefly and forgot. This means for these nights, efficiency may be lower than your subjective feel.

• Restorative/Low deep sleep:
  Restorative sleep has a lot of deep sleep, and you usually feel better after restorative sleep. If you have too little deep sleep, “low deep sleep” will be shown.
• Barely asleep:
  Your sleep consists too much of light sleep, and did not go into deep sleep or REM sleep. This can occur due to many factors such as alcohol intake.
• Woken frequently:
  You were woken too many times during your sleep. One caveat is that you might have felt like you were asleep the whole time, but you may have been awake physiologically, or woke up briefly and forgot. Or the device was unable to detect you multiple times throughout the night, and considered these moments as you leaving the bed.
• Low REM:
  You did not have enough REM sleep. REM sleep is the stage when you dream, and not having enough REM may lead to tiredness when you wake up.
• Fast-to-sleep:
  You fell asleep fast after you actively tried to sleep. However, this is a prediction rather than a measurement, and may be different if you hung out in bed for a long time before you actively tried to sleep.
• Slow-to-sleep:
  You had trouble falling asleep after you actively tried to sleep. However, this is a prediction rather than a measurement, and may be different if you hung out in bed for a long time before you actively tried to sleep.
• Sufficient/Insufficient:
  Your sleep duration was sufficient/insufficient.
• Good/Bad wake up:
  The ideal state to wake up is at a light sleep stage. Good wake up indicates that you woke up in the light sleep stage, while bad wake up indicates that you woke up in deep sleep or REM sleep stage. When you wake up in a light sleep stage, you usually have a much better time in the morning without grogginess.
• Missing/No data:
  The device was unable to detect more than 3 hours of sleep from you last night.
• Some debt:
  You did not sleep enough and have incurred sleep debt.
