I've already purchased a U by Moen shower, do I need a new controller to integrate voice automation with Apple HomeKit?
In order to determine if your controller will be compatible with Apple HomeKit, you will need to look at the box the controller came in. If there is a sticker on the box that states, "Works with Apple HomeKit", it will be compatible with Apple HomeKit. If you have already downloaded the U by Moen app onto your smartphone, and provided automatic approval of updates, the app will push the update with Apple HomeKit automatically to your device. You will receive a notification when this feature becomes available.
If your controller arrived in a box that does not have the "Works with HomeKit" sticker, it will not be compatible with HomeKit.
