I’ve used HomeKit (with AppleTV 4th Gen as home hub) since the beginning, with lots of compatible devices (mostly Lutron), and it has consistently worked really well. I just switched my router from an Apple Time Capsule to Netgear Orbi, and ever since I’ve been having trouble with the AppleTV doing the hub function consistently: Remote Access frequently doesn’t work, and neither do my Home app automations. When I’m at home everything works ok when I control it through the Home app or the device manufacturer’s app (e.g. Lutron app, iDevices, etc). That is to say if I try to control a specific device through either app, it works ok. When I’m away from home the Home app will usually (but not always) claim “No devices responding”, though I can control them through the third party app (e.g. Lutron), and under “Home Hubs” in the Home app it shows “AppleTV: Connected”. My Home app automations are usually broken whether I’m at home or away. The usually don’t run. When I’m home they work ok if I tap “test this automation”, but they don’t run automatically on their own. It seems that the problem is all about the AppleTV not working as the hub now. Everything worked great before I set up the new router. The AppleTV is connected ok (Wi-Fi/data) to the new router for streaming, etc. I have restarted it, signed out/in of iCloud, reconnected to the router, etc. Anyone have any idea what might be wrong, or how I can get the AppleTV to consistently perform the hub function with the new router?
