An iCloud Settings error means the Lyric mobile device is having trouble connecting with Apple® HomeKit™. Try verifying your iCloud settings and your Lyric app permissions.
Update the iOS software to the latest version. The Lyric app is compatible with versions 9.0 or higher. Be sure you are using the latest Lyric app, available in the Apple App Store.
On your iOS smartphone or tablet, go to Settings > iCloud. Ensure you are actively signed in to iCloud, that your iCloud Drive is On, and that iCloud Keychain is On.
If iCloud does not appear or if you are still experiencing issues, turn off your iCloud Keychain. Then turn back on. It may take several minutes for the synchronization to complete. To learn more about iCloud syncing issue, click here.
Verify your lyric app permissions to ensure that Home Data is turned on. If you don't allow the app to access Home Data, you will not be able to finish installing your Lyric thermostat or use the HomeKit integration or Siri with your thermostat. In your mobile device, go to Settings > Lyric. Turn Home Date to On.
