How does it compare with a smartwatch?
The difference is not simply what they track. It’s how you keep tracking.

Smartwatch features and charging routines vary by model.
If you want one device for workouts, notifications and everyday activity, a smartwatch may be the better choice.
But if you want to keep tracking your sleep without wearing a device to bed, wellune-A1 offers a different way.
Set it up once. Then just sleep.
Mount it by your bed and make tracking part of your night.

wellune-A1 uses a 60GHz radar sensor to detect subtle movements and breathing-related signals while you sleep.
It tracks your sleep without recording video or audio.

Do I need to wear anything while I sleep?
No. wellune-A1 is installed near your bed and senses movement and breathing-related signals without being worn on your body.
Do I have to start tracking every night?
You don’t need to start tracking manually each night after setup. Keep the device correctly installed, powered and connected to Wi-Fi. A sleep record is available only if the device successfully collects enough sleep data.
Does wellune-A1 record video or audio?
No. It uses radar sensing rather than a camera or microphone to track your sleep.
Is there a monthly subscription fee?
No. AI Sleep Care Service is included with the current wellune-A1 package, with no monthly subscription fee.
Is wellune-A1 a medical device?
No. wellune-A1 is for wellness and everyday sleep tracking. It does not provide a medical diagnosis or replace a clinical sleep test.
Can two people sleep in the same bed?
Multiple people in the same sensing area may affect measurements. Do not assume one device can distinguish and track two people at once. Contact support about your sleeping arrangement before buying.
Where and how high should I install it?
Mount it on the wall at the head of your bed, aiming the sensor toward your chest. The sensor must be no more than 2m away from you, measured in a straight line. A position 0.5–1m above your head when sleeping is recommended. Keep the sensing path clear of obstructions.
Can I mount it on the wall?
Yes. Register the device in the app before attaching it, because you need the QR code on the back. If double-sided tape cannot hold it securely, use the included fixing screws. Cable holders are included.
What Wi-Fi and power connection do I need?
A 2.4GHz Wi-Fi network and its password are required. The device uses continuous 5V DC power (3W). Its fixed 4m USB Type-A power cable is attached to the device and cannot be detached. A power adapter is included.
Can I turn off the light at night?
Yes. You can turn off the device’s LED indicator in the wellune app. Measurement continues to work with the indicator off.
What if I change my phone?
Contact wellune support for help moving to your new phone. Check with support before resetting the sensor when you switch phones.
What if a sleep record is missing?
Check that the sensor faces your chest, is within 2m, and has a clear sensing path. Confirm that power and network connections are working. The device also needs enough sleep data to generate a report. If the issue continues, contact support.
