Our home network comprises Work, Home and IOT Networks with the Home Network including an Apple TV, NAS and various personal computers. We are now installing a number of smart home devices and using the new Thread protocol as the basis which, by default, sees the devices connected to the Apple TV as the Thread Boarder Router. My concern is that these IOT devices are, in effect, will then be part of the trusted Home Network and I’m looking for advice about how to address this concern. The simplest option is to move the Apple TV is into the IOT Network sitting beside some (legacy) Wi-Fi based smart devices and supporting the Thread-enabled smart devices. This model exposes the Apple TV (which is linked to our Apple ID) to the IOT devices although I'm unsure as to how much of an issue this is given that tvOS is kept up-to-date etc. Another option is to use another Thread Boarder Router such as https://www.kirale.com/products/ktbrn1/ or Nanoleaf Elements but I think that this precludes use of Apple HomeKit to manage the environment. Any advice on how to secure such a set-up?
