If you no longer have the HomeKit accessory you want, or just need to delete a phantom entry in your HomeKit home, it’s easy to do—if you know where to look. Let’s remove the HomeKit device now and walk you through the process.
In our case, we had a problem with our Schlage Sense smart lock and decided to just reset it to factory settings before adding it back to our HomeKit home. Having successfully done this, we realized that we had not deleted the old entry from HomeKit, and now we had two smart locks installed — one worked fine, and the other constantly complained about HomeKit. While you may find yourself in the same situation, you can also simply remove the device entirely because you no longer use it, got rid of it, or for a variety of reasons.
To do this, open the Home app on any iOS device that is owned by a HomeKit administrator (a HomeKit administrator is the person whose iCloud account was used to set up the HomeKit system). Select an entry in the bottom navigation bar for «Rooms».
The device we want to remove is actually right on our home screen in the Featured Accessories category, but it won’t be front and center for everyone, so we’ll drill one layer deeper into the menu. In the Rooms menu, swipe left or right until you find the room where the device is located. If you’ve never assigned a device to a room, it will, like our smart lock, be in the Default Room panel.
Press and hold the entry for the device you want to remove from your HomeKit home. This will open a more detailed entry for the device.
