@davextreme Yep, with homekit. I have the Virtual LAN's set up such that the "main" network can talk to the IoT network (and they can reply) but the IoT network can't talk to the main network (at least not without an established connection originating from the main network). The IoT stuff can also talk to the internet. I actually currently have my AppletTV (which is my Homkit hub) on the main network though I may experiment with putting it on the IoT network (though I'm concerned it won't be able to reach my iMac when I want to watch stuff on Plex or from my DVR). I actually feel like a modern AppleTV is probably secure enough to stay on the main network. And since it can talk to the devices on the IoT network it can still act as a hub just fine.
