Eve — Each accessory can only pair with one iPhone/iPad/iPod touch — set up device sharing

HomeKit accessory, including Eve accessories, can only be paired with one master iOS device.

To share your Eve accessories, you can set up other iOS devices using the same Apple ID as the master iOS device, and iCloud will sync the HomeKit setup across the other devices (which can take up to two hours.) After that, Eve will automatically be able to use the master device's setup. To enable iCloud syncing of HomeKit data, you need to enable the iCloud keychain on all devices.
