I found out that I can use Apple TV 4K as a hub to control my HomeKit accessories when using 4G or a non-home WiFi network. The light control works perfectly via 4G, but my Hue motion sensor doesn’t seem to be connected via the hub. The sensor also disappears in the Apple Home application as soon as I disconnect from WiFi at home (the lights are still accessible that way). Hur motion sensor automation doesn’t work when switching to 4G either.
Does anyone have an idea how to solve this problem? I would like to turn on my lights on the go, even when I’m not connected to WiFi.
