  1. Open Settings → Sleep tracking → Wearables → Use wearable.

  2. Choose the correct option from the list.

  3. For HR data enable Settings → Sleep tracking → Wearable → Heart rate monitoring.

Note Sleep tracking collects data the whole night and they are analyzed in real-time. This means the watch must stay connected with BT during sleep tracking.

5. HR monitoring

Check your HR settings in the Mi Fit app.
When the Mi Band is in Sleep Assistant HR mode in Mi Fit, it doesn’t feed the HR data to Mi Band Tools / Sleep as Android. When it is in regular HR tracking mode (24-hour), it works.

Sleep tracking with Wear OS device requires a companion app installed from the Play Store on the watch.

How to get there:

  1. Make sure the watch is connected to the phone.

  2. Go to app list on your watch, select Play Store.

  3. Find Sleep as Android and select Install.

  4. After the companion app is installed, you can enable the connection in Settings → Wearables → Use wearable → Wear OS.

  5. Test the connection in Settings → Wearables → Test sensor - you should see a graph reacting to your movement (a short delay is normal, data are sent in batches).

Note Sleep tracking collects data the night and they are analyzed in real-time. This means the watch must stay connected with BT during sleep tracking.

All currently supported devices can be found at list of compatible devices.

If you’d like us to integrate another device, please submit it as a suggestion to our Suggestion Forum. Also, please check if the device has an API so we can integrate it.

On the Wear OS platform and ONE UI Watch (Galaxy Watch 4 + 5), we use gentle vibrations for an even more natural wake up.
It starts with a single vibration, another in 30s, then again in 20s and so on. After a few minutes, the vibrations become continuous.

If you’re worried that’s not enough, you can set a delayed start of alarm sound on the phone. And there is always the backup alarm.

This can be the result of several things, so please try the following troubleshooting steps:

  1. Make sure you have Sleep as Android Gear Addon installed on your phone and updated to the latest version.

  2. It may happen that the addon can not be started by us if it was force stopped before. In this case, please go to the Play Store app on your phone, open addon page, tap "OPEN".

  3. Disable all battery savers on your phone for all involved apps (Sleep as Android, Sleep as Android Gear Addon, Samsung Accessory Services) - to find out how to do this, please visit

  4. Samsung Accessory Services sometimes misbehaves and prevents 3rd party apps from connecting to the watch. Please uninstall and reinstall it.

  1. Please make sure that you are not accidentally starting the Sleep as Android app from your watch. This would start sleep tracking immediately.

  2. Make sure you are not using automatic start of sleep tracking in Settings → Sleep tracking → Automatic sleep tracking → Start sleep tracking.
