Home setup of 2 wifi network

Hello,

I hope my problem has an easy solution.

I have 2 separate wifi networks from 2 different service providers at my home.

1. In first area of my home, 1 wifi network working on TP LINK ARCHER AX11000. I have placed a HomePod mini as a hub.

2. In second area Deco M9 Plus mesh wifi system is working with apple tv 4k as a hub.

in my home app only of the either hub is connected at a time. And the second device says “home hub disconnected”. Home app automatically switches which hub is working. And only devices briged through that hub shows connected in app.

if I take my iphone in a region where the home hub is not working, home app considers the iphone as a home hub and start devices connected on that network.

how can I make homkit work on 2 seperate wifi?
