Where can I see which Apple TV or HomePod is acting as my Home Hub?
This information lives in Apple's own Home app, not in On Cue Home — here's how to find it:
Open the Home app on your iPhone or iPad
Tap the house icon in the top-left corner (or your home's name) to open Home Settings
Tap Hubs & Bridges
This screen shows your current Active Home Hub, lets you turn Automatic Selection on or off, and shows every Apple TV or HomePod in your home that's eligible to act as a hub. Any Apple TV (4th generation or later) or HomePod on the same home network can serve as a hub — having at least one means your accessories stay controllable and automations keep running even when you're away from home.
