If you see a "Home Hub Required" error message
If you're trying to set up a home accessory and you're seeing this error message, you need a device set up as a home hub.
If you already have a home hub set up
Follow these steps. After each step, try to pair your accessory again.
Turn your home hub device off then on.
Try using a device that's signed in to the Apple ID account that was used to set up the Home app.
If your home hub is an Apple TV that's connected to the internet with an Ethernet cable, connect your Apple TV to Wi-Fi instead. Connect it to the same Wi-Fi network that your iOS device is on.
Check that your Wi-Fi is connected and there is no interference.
Reset the network settings on your iOS device that has the error message.
