Preparations

Mi Band 7 only

  • Modified Zepp App (registration required)
  • You need to connect Mi Band 7 to Modified Zepp App the same way you would with Zepp Life (google auth is not supported)
  • You can use the official Zepp App, but have to create a custom QR code. Follow this guide for the URL of the QR code you have to adapt.

General steps

  • Download the official Zepp App
  • You need to enable Developer Mode in Zepp app
  • Build and install the ha-zepp application yourself using the Zeus CLI
  • Open the application settings and specify the addresses of Home Assistant, Long-lived access token and select the sensors you want to display on Zepp OS device

Home Assistant

  • Long-lived access token (you can generate it on your-ha-instance.local/profile page)
  • "If you are not using the frontend in your setup then you need to add the api integration to your configuration.yaml file."

About the sensor updates to the Home Assitant REST API

Since it is not possible for the general public to access Huami's WEB API, I decided to make a background updater within this app to send the wearable sensor data to Home Assistant. It uses the alarm mechanism, which can open a page even when the device is inactive. When this page is opened, the POST requests are performed towards the HA REST API. However, notifications on the device (e.g. app notifications or the calendar notification) are remained open for a while (if you don't swipe it away), which can block this alarm mechanism from showing the ha-zepp page. If the ha-zepp page is blocked by a notification, you will see that if you swipe it away, the ha-zepp page will appear. If you don't swipe it away, the ZeppOS system eventually will remove all stored pages and notifications to save RAM and be more power efficient. If this ha-zepp page is not openend, ha-zepp is unable to create a new alarm, meaning the background updater will break. Therefore, it's best to DISABLE ALL SORT OF NOTIFICATIONS if you want this feature to work properly.
