Due to a bug introduced in tvOS 15.4, if you have multiple Apple TVs in your home configured as Apple HomeKit hubs, or if you have HomePods together with at least one Apple TV configured as an Apple HomeKit hub, you may experience issues when viewing camera streams on Apple TV and sometimes Apple Watch, for example, grey screens or messages saying 'Disconnected' or 'No Response'.
This issue is not specific to Starling Home Hub, and affects all cameras that connect to HomeKit via a bridge.
To fix this issue:
- If you do not have HomePods, you will need to disable the Apple HomeKit hub function on all except a single Apple TV in your home
- If you have HomePods, you will need to enable a setting on Starling Home Hub to change the way the hub adds cameras to HomeKit
This will not adversely affect your smart home functionality: after following these instructions, you will be able to view your cameras on every Apple TV in your home.
If you do not have HomePods
First, on your iPhone or iPad, go to the Apple Home app. Press the '...' icon top right, Home Settings, Home Hubs & Bridges and take a note of all Apple TVs listed in the HOME HUBS section. In the example below, the Apple TVs are listed as Living Room, Basement Theater and Upstairs Den.
Now choose one of these Apple TVs - it does not matter which - to remain as your Apple HomeKit hub, and disable this function for the others.
In this example, you could choose Living Room to remain as your Apple HomeKit hub. You would therefore disable the Apple HomeKit hub function on the Basement Theater and Upstairs Den Apple TVs by going to each of those two Apple TVs in turn, navigating to Settings, AirPlay and HomeKit and under HOME HUB, change to Disconnected.
Finally, power cycle all the Apple TVs in your home by pulling the power cord out, waiting 5 seconds, and plugging back in.
If you have HomePods
First, on your iPhone or iPad, go to the Starling app, Advanced Settings, then enable Publish cameras as unbridged HomeKit accessories. This will temporarily remove your Nest cameras from HomeKit.
Then, after around a minute (to allow an iCloud sync), go to the Apple Home app on your iPhone or iPad, press ‘+’, Add Accessory, then scan the QR code on the base of the hub. This will re-add one camera. If you have more than one camera, press ‘+’, Add Accessory, then scan the QR code on the base of the hub again to add the second camera, and repeat until all the cameras have been re-added.
