Step by step
Identify the source of the duplication
Open the Home app and locate the duplicated accessory. Tap the device tile, select Accessory Details, and check the 'Bridge' information at the bottom to determine which manufacturer bridge is reporting the device.
Note: Duplicates often occur when a device is connected via both Matter and a proprietary cloud integration.Remove redundant third-party integrations
Open the native app for the device manufacturer. Navigate to Settings and locate Linked Services or Third-Party Integrations to see if multiple bridges are authorized to sync the same hardware.
Note: Deauthorize the older or redundant service to stop the data feed.Delete the redundant device tile
In the Home app, long-press the duplicate device tile. Tap Accessory Settings, scroll to the bottom, and select Remove Accessory to excise the ghost entry from your Home configuration.
Restart the Home Hub
Force a state refresh by power cycling your Home Hub. If using an Apple TV, go to Settings > System > Restart; if using a HomePod, unplug the device for 10 seconds and reconnect.
Note: This forces the Home Hub to rebuild the accessory cache based on current network availability.Verify device status consistency
Test the remaining device tile by toggling it on and off. If the device fails to respond, perform a hard factory reset on the physical hardware and add it back as a fresh accessory to establish a clean configuration.
