1. After a device is removed, you will receive a device removal message, and conditions and actions related to this device will be deleted from automation or scene settings.
2. If the removed device is the only device in automation settings, the automation settings will change to scene settings.
3. If the removed device is the only action in a scene, the scene will be deleted. (If you are viewing the page of the scene when it is deleted, the scene will disappear only after you reload the scene list.)
