Home Assistant has deep integration with the Apple Watch. You can display Home Assistant information as complications directly on your watch face or launch actions from the Watch app.

The Apple Watch integration requires watchOS 5. In order to install watchOS 5 you must have an iPhone 5s or later with iOS 12 or later, and an Apple Watch Series 1 through 4. The first-generation Series 0 Apple Watch is not compatible with watchOS 5. You can identify your Apple Watch model here.

Manual Sync Procedure

By default the app will sync your complications every 30 minutes although the first update after creating a complication may take longer. To try and force a manual sync, follow these steps:

  1. In the Home Assistant Companion app, navigate to App Configuration -> Apple Watch and stay on that screen.
  2. Now launch the Home Assistant Apple Watch app.
  3. Press the Back button inside Home Assistant Companion mobile app, bringing you back to the main settings screen.
  4. Press "Done" in the top right to sync and update the complications on your Apple Watch.

Data will update much more frequently if Background Fetch is turned on and if the face containing the complication is left selected.
