Xiaomi-Mi-Band-8-Surfr-Watchface-Notifications
Display the height of the last jump, maximum jump height of our session and number of jumps on your Xiaomi Mi Band 8. Based on the data measured on your android phone by the surfr app. Vibrate the band on every jump.
This tutorial is only working with the Xiaomi MI Band 8. Not with the Xiaomi Mi Band 8 Active or other Smartbands. However it should be possible to use other bands. For the watches supported by https://github.com/m0tral/EasyFace it should be simple. Just ask me in the issues. It is also possible to customize the watch face.
There are some apps and tools involved
- The Mi Band 8 is setup with the official Mi Fitness app to receive the auth key: https://play.google.com/store/apps/details?id=com.xiaomi.wearable&hl=de&gl=US
- The Band uses a special watchface to display the jump data: https://github.com/Chriz76/Xiaomi-Mi-Band-8-Surfr-Watchface-Notifications/blob/main/watch-face.zip
- The watchface is installed via the app "Mi Band 8 Watch Faces" on the Band: https://play.google.com/store/apps/details?id=asn.ark.miband8&hl=de&gl=US&pli=1
- The surfr app runs in wetsuit mode and automatically creates an android broadcast on every jump: https://play.google.com/store/apps/details?id=com.kiter&hl=de&gl=US
- The Automate app intercepts surfr's broadcasts, converts them to a special format, increases the jump count, the max jump height and sends all data to the gadgetbridge app and also tells gadgetbridge to vibrate the band: https://play.google.com/store/apps/details?id=com.llamalab.automate&hl=de&gl=US
- Automate uses the two flows:
- Gadgetbridge is connected to the Mi Band 8 and sends the jump data to the Band and tells it to vibrate: https://freeyourgadget.codeberg.page/fdroid/repo/nodomain.freeyourgadget.gadgetbridge.nightly_nopebble_0.80.0-9ba96231c.apk
- The Band vibrates and displays the jump data
Howto make it work
Warning: This may break your Band. So do it on your own risk.
