Hi there Antropod215,
It looks like you have some questions about the Home app on your iPad. We can certainly help shed some light on this. It seems that you may have completed the upgrade to the new Home architecture on iPad. You can read more about that at Upgrade to the new Home architecture on iPad - Apple Support, however there have been changes such as:
"Note: A home hub such as Apple TV (4th generation or later) or HomePod is required for features such as remote access, sharing your Home, notifications, automations, HomeKit Secure Video, and Adaptive Lighting. iPad is not supported as a home hub with the new Home architecture. You can continue to use the Home app on iPad to connect and control your smart home accessories."
If you currently own an Apple TV or HomePod, follow the steps here to complete the process across all devices: Upgrade to the new Home architecture - Apple Support
If you have additional questions or concerns, reach out to Apple so they can look into additional options with you at: Get Support
Thanks!
