Yes, multiple iOS devices can control Apple HomeKit devices. To do this, users need to ensure that all devices are linked to the same Apple ID and connected to the same Wi-Fi network. HomeKit uses iCloud to synchronize settings and device information, allowing anyone with access to the Home app on their iOS devices to control the connected accessories. In addition, users can share control of their HomeKit setup with other family members through the Home app. By inviting others using their Apple IDs, each member can access and manage the devices from their own iOS devices. It is advisable to check the settings within the Home app to manage shared access and control permissions. For specific details on sharing features and options, visiting Apple’s official website may provide additional information and guidance.
