No Response in HomeKit

Have you experienced a “No Response” sporadically in HomeKit? I think I may have found the reason why it was happening to me so frequently. My HomeKit has 13 devices that serve as Home Hubs. I have several Apple TVs, Home Pod 2s, HomePod Minis and an iPad Pro. I have found that when my HomeKit uses a HomePod Mini as the Home Hub there are 4 - 6 devices that will show as “No Response”. Once I force HomeKit to use a different Home Hub, preferably an Apple TV (latest version), all of the “No Response”s go away. I would like to see some way to assign the function of Home Hub to a specific Apple device, or at least give us a way to turn on and off the ability for each device to be used as the Home Hub.
