Protect accessories with a router in Home on Mac
You can make your smart home more secure by allowing a compatible router to control which services your HomeKit accessories can communicate with in your home Wi-Fi network and on the internet. HomeKit-enabled routers require that you have a HomePod mini, HomePod, Apple TV, or iPad set up as a home hub. See the Home accessories website for a list of compatible routers.
Important: iPad won’t be supported as a home hub on the new Home architecture, which is more reliable and efficient, and which will be available later this year as a separate upgrade in the Home app.
Set up your secure router on your iPhone or iPad. See the Apple Support article Use routers secured with HomeKit.
