It sounds like you're experiencing an issue with the Home app on your iPhone. Here are some steps you can try to resolve this problem:
1. **Check iCloud**: Make sure you're signed in with the same Apple ID on both your iPhone and other devices where your home setup is visible. The Home app relies on iCloud to sync your home data.
2. **Restart Your iPhone**: Sometimes, a simple restart can resolve issues. Restart your iPhone and check if your home setup appears in the Home app.
3. **Update iOS**: Ensure that your iPhone is running the latest version of iOS. Sometimes, updating to the latest iOS version can resolve compatibility issues.
4. **Reset Home App**: Try resetting the Home app on your iPhone. Go to "Settings" > "Privacy" > "HomeKit" and tap on "Reset Home Configuration." This will remove your home data from the Home app on your iPhone. You can then set it up again.
5. **Check Home Sharing**: If you're using Home Sharing with your Mac and other devices, make sure it's enabled and configured correctly. Check the "Home Sharing" settings on your Mac.
6. **Re-Invite to Home**: If the issue persists, try asking another member of your Home setup (e.g., an iPad) to re-invite your iPhone to the home. This can sometimes trigger a re-sync of your home data.
7. **Contact Apple Support**: If none of the above steps work, it's a good idea to contact Apple Support. They can provide more specific guidance and may be able to troubleshoot the issue further.
Remember that HomeKit and Home app data are tied to your Apple ID and iCloud, so ensuring that all your devices are using the same Apple ID and are properly connected to iCloud is crucial for syncing your home setup across devices.
