Apple TV HD 4th generation home hub is not responding
I have an apple tv hd 4th generation running TVOS 14.0 that is my HomeKit hub. I use the home app a lot and have a good number of devices connected to HomeKit, including 4 home kits secure video cameras. Several times a day, I have a notification stating either "A home hub is not responding" or "All home hubs are not responding". Anywhere from 1 to 15 mins later I will get a "A home hub is responding" message. This happens every day, multiple times a day. It is quite annoying.
The Apple TV is plugged in via ethernet to my network. There are no updates to install, and rebooting the Apple TV has no effect.
My assumption is the Apple TV HD is simply not capable of performing the volume of tasks being asked of it by HomeKit, or goes into some kind of sleep mode that HomeKit struggles to wake it from? I don't want to have to replace the Apple TV just to fix this, as its advertised as being able to handle this job, so hoping there's another solution?
