Tools & Mi Band and Amazfit#

Using Tools & Mi Band or Tools & Amazfit with Sleep as Android unlocks advanced sleep tracking features, heart rate monitoring, and tactile alarm vibrations on your Xiaomi or Amazfit wearable.

To connect Sleep as Android with your device, we integrate via the third-party Tools companion app series (developed by Tools & Wearables):

Because Xiaomi and Amazfit wearables do not provide an open API for direct integration, Sleep as Android relies on these third-party bridge apps to communicate with your device.

Setup Guide#

Connecting your band takes just a few quick steps across both apps:

Step 1: Configure the Tools App#

Make sure all Do Not Disturb (DND) modes on your wearable are turned off or scheduled properly during sleep, as active DND modes can block alarm vibrations.

Step 2: Configure Sleep as Android#

  1. Open Sleep as Android on your phone.
  2. Go to Settings → Sleep tracking → Wearables → Wearables.
  3. Select your corresponding Tools app (Tools & Mi Band or Tools & Amazfit) from the list.
  4. (Optional) To track heart rate, toggle on Heart rate monitoring in the same menu.

Sensor data is analyzed continuously in real time. Keep Bluetooth turned on on your phone throughout the night.

Setting Up Heart Rate (HR) Monitoring#

To ensure accurate, continuous heart rate readings during sleep tracking, check both your official band app and the Tools app:

  1. Official App Setting (Mi Fitness / Zepp): Ensure your band is set to regular 24-hour HR tracking mode.
    • Avoid using “Sleep Assistant HR” mode in the official app, as it prevents external apps like Tools from accessing HR data.
  2. Tools App Setting:
    • Open the Tools app menu (☰ in the top left).
    • Navigate to Heart Rate and tap the Settings icon (⚙️).
    • Enable Heart Rate Monitor.

Using Wristband Buttons to Snooze or Dismiss Alarms#

You can use the physical button or touch button on your band to control your alarm:

  1. Open the Tools app menu (☰).
  2. Go to Settings → Sleep as Android → Mi Band / Amazfit Button Action.
  3. Select your preferred action:
    • None: Button will not affect the alarm.
    • Snooze: Pressing the button snoozes your phone alarm.
    • Dismiss: Pressing the button turns off the alarm.

Customizing Alarm Vibrations#

You can customize the pattern, length, and frequency of alarm vibrations on your band:

1. Enable Priority Override#

Pull down your phone’s notification bar, locate the Tools app status bar notification, and tap the first icon until you enter Priority Override mode (indicated by an exclamation mark ! icon).

2. Enable Wearable Alarms in Sleep as Android#

Open Sleep as Android and go to Settings → Sleep tracking → Wearables → Alarm and enable wearable vibrations.

3. Customize Patterns in the Tools App#

  1. Open the Tools app menu (☰).
  2. Go to Settings → Sleep as Android → Custom vibration.
  3. Adjust the vibration count, duration, and delay between vibrations.
  4. Tap Test vibration to preview your pattern.

❓ FAQs & Troubleshooting#

How do I set up a silent alarm that vibrates only on my wearable?
  • Reason: Desire for a quiet wake-up call without disturbing others.

  • 👉 Fix:

    1. Choose your sound preference:
      • Silent: In the specific alarm’s settings, go to Sound and select Silent.
      • Vibration first, sound later: Go to Settings ➔ Alarms ➔ Sound delay.
    2. Turn on watch vibrations: Go to Settings ➔ Sleep tracking ➔ Wearables ➔ Alarm and choose From start.

    We recommend using a delayed sound rather than complete silence as a safety net, especially if your backup alarm is also set to silent.

Why does my connection keep dropping or show red gaps on the sleep graph?
  • Reason: Android’s background battery optimizations aggressively closing apps or killing Bluetooth connections.

  • 👉 Fix: Exclude all involved components from background battery optimization on your phone:

    1. Sleep as Android
    2. Your bridge app (Tools & Mi Band or Tools & Amazfit)
    3. Your official band companion app (Mi Fitness, Zepp, or Mi Fit)
    4. Bluetooth system services
